Casting Out Nines has officially moved

A while back I announced that this blog was being folded into the Chronicle of Higher Education Blog Network. I’m pleased to announce that the move has officially taken place. You can check out Casting Out Nines v. 2.0 (or whatever version I’m up to) at

http://chronicle.com/blognetwork/castingoutnines/

I want to give the folks at the Chronicle a lot of kudos for the excellent visual design work they’ve done on the new site. It’s minimalist — which I like — but also has some very nice stylistic touches. I hope the content will match the quality of the look.

This post will be the last one made to this WordPress.com site. All future posts will be made at the new place. All the old content that is here at WordPress.com has been (as far as I know) successfully ported to the new site, with the exception of comments that have been made in the last week. I’ll be keeping this WordPress.com site open for archival purposes because it’s no cost to me. But I will probably close comments on all the posts at some point to make sure nobody’s comments end up getting “lost” on this site.

Just a few notes to close things out here:

• The Chronicle folks are working on having the URL for the WordPress.com site just redirect to the new site, but it turns out there are some issues with that. It’s probably best if you just change the URL in your bookmarks to the new one.
• Likewise, if you’re reading this blog via RSS, you probably need to change your subscription link. The new link is http://chronicle.com/blognetwork/castingoutnines/feed/ for posts and http://chronicle.com/blognetwork/castingoutnines/comments/feed/ for comments.
• There does not appear to be a way to subscribe to CO9’s by email at the new site. There are 33 of you who subscribe this way, and I appreciate that! If I were you, I’d switch to using an RSS reader — they are free and very easy to use.
• Finally, I want to give a big shout out to WordPress.com. I switched from a self-hosted WordPress site to WP.com back in 2007 after a maddening series of bandwidth issues that happened while I was on the road. I thought at the time that I was downgrading, but actually WP.com has been a fantastic service that’s only gotten better over time. Anybody considering a blog would do well to check this platform out to see what they have to offer.

See you on the other side!

Friday Random 10, 8/26/11

Don’t look now, but it’s the return of the Friday Random 10. Ten songs selected at random from my family’s, um, eclectic iTunes library. Notice how I say “my family’s” library, so as to deflect questions about why there are so many kids’ songs or Glee stuff coming up.

1. Candles (Glee cast version); Glee: The Music Presents the Warblers
2. Spiritual; Johnny Cash, Unchained
3. BWV Praeludium et Fuga in A; James Kibbie, Bach Organ Works: Preludes and Fugues
4. Sara; Fleetwood Mac, Greatest Hits
5. It Doesn’t Matter; Alison Krauss & Union Station, So Long So Wrong
6. Celebration; Kool & the Gang, Gold
7. Amazed; Lonestar, Lonely Grill
8. All the Way My Savior Leads Me; Rich Mullins, The World as Best I Remember It, vol. 2
9. Soul Refreshing; Robert Randolph & The Family Band, Unclassified
10. Jealous Hearted Man; Muddy Waters, Hard Again

Let’s focus this week on James Kibbie, a master organist at the University of Michigan. What’s great about Kibbie, aside from his amazing talent, is that he recently made the entire catalogue of his Bach recordings available as free downloads on his website. Go look at that website — this is a lot of music. What a great gift to the world and for all of us who love beautiful music. I think I got about 12 hours’ worth from there myself, including the track listed above, and once I finish all of that, I’ll be back.

I couldn’t find any video of Dr. Kibbie, but here’s a video of Scott Dettra playing Bach on the organ at West Point.

Good enough teaching, and trust

http://www.flickr.com/photos/nitsrejk/

I spent most of Wednesday at the 17th annual Fall Conference on Teaching and Learning, put on by my new employer, Grand Valley State University. It was a full day of good ideas and good people, and I really enjoyed engaging with both. One experience from today  has really stuck with me, and it happened during the opening session as Kathleen Bailey, professor in the Criminal Justice department, was speaking about the changing student demographic we are encountering (not just at GVSU but everywhere in higher ed).

Kathleen comes from a fairly unique position as not only a professor of CJ and assistant director of freshman orientation but also as a former parole officer for teenagers. In her talk, she drew some parallels between parenting, being a parole officer, and working with college students. I was pretty uncomfortable with that three-way comparison at first, but the more she spoke, the more I had to admit the similarities were pretty striking. She spoke about three conditions that troubled teens — and indeed all children — need to have if they are to thrive:

1. Kids need to have a good “holding environment” — that is, they need to be in a place where they have a feeling of safety and attachment, and to some extent basic respect as a human being.
2. Having found a good holding environment, kids then need to have provision of contrasting or contradicting experiences — what Kathleen called “differentiation” — to develop a defined sense of self. For example, a kid who has violent behavioral tendencies needs to be given experiences where he cares about others and acts in appropriate ways, to be shown that he can be kind and gentle and does not have to always follow his tendencies.
3. Finally, kids need to have an abiding presence of someone else — a person who “stays put” with them and gives them a safe place to integrate all the personal changes they experience through differentiation.

This process is all about building the substrate of a relationship with a kid upon which a mature, productive person can be built. The building process has to be carried out by the kid — the kid with violent tendencies has to choose to act differently, and nobody else can to that for him — but the change that takes place cannot happen in the absence of that “abiding presence” that creates the environment.

Probably by now the comparison with parenting and teaching should be clear. These, too, are about transforming the lives of young people through the presence and enabling work of another person. Kathleen referenced the notion of good-enough parenting (espoused by psychoanalyst Donald Winnicott) as a model for this kind of relationship. It’s not about being perfect or doing the right things all the time, but rather about “attuning” to the child who is in your care — that is, to attempt to respond to the needs of the child/kid/student, especially emotional needs. The ideal result is that the child/kid/student has a sense of being understood, cared for, and valued. (That’s paraphrased from the article linked just above.)

We faculty tend to focus on covering our content and drilling students to ensure they are mastering a skill set. These things aren’t unimportant. But for students, particularly new students entering into college or university, there is a strong emotional component that intermediates the learning process. They tend to be unsure of themselves; they are struggling to make social connections in a new place; they struggle with homesickness; they are inexperienced at managing freedom and end up making poor personal choices. On top of all this, if we faculty are doing our jobs, we’re asking them to stick their necks out and work harder than they ever have, and wrestle with ideas that are just beyond their grasp. So of course there is a lot of emotional stress at play. It behooves us to build this substrate of a relationship where students have those three things they need to thrive.

I am certainly not good at this sort of thing. I am an introvert and a geek, and emotional stuff like this is not my forte. But I take away two profound things from Kathleen’s talk. First, my personal preferences are irrelevant. If students are going to learn in my classes, they must have a sense that they have from me the basic respect afforded to all people, especially those embarking on a journey through a university education. Second, I can take comfort that all I have to be is “good enough”. From the article I linked earlier:

As parents, we all naturally fail at times. But if we are committed to parenting as important work, we will be able to correct our mistakes and learn from the experience. Children do not need “perfect” parents. However children do need parents they can trust to reflect on their actions and attempt to bridge misunderstandings when they occur. This working through is an act of attunement and strengthens the bond between parent and child.

It is essential to remember that our failures can in part create the healthy disappointments that children must work through to gain strength. However, these are the inevitable failures that occur, despite our best and determined efforts to be attuned and to provide the most optimal environment we can for our children. Therefore we will not have to concern ourselves with perfection. Thankfully we can narrow our focus to being the best parent we can along this path of family making we have all chosen, and turn our attention towards a deeper understanding of what it means to be attuned to our children.

That ought to be something all parents and teachers keep in mind every day. (Parole officers too, I suppose.

I suppose all this boils down to the concept of trust. Students need to know that they can trust me. I need to invest trust in my students (even though they, as imperfect people and works-in-progress, will break that trust). On a bigger level, my colleagues and I have to have a mutual sense of trust to work together. My Dean needs to trust me, and I him. In fact the whole fabric of higher education is predicated on trust. No one can learn or teach in a college where the network of trust is not iron-clad. If trust is missing from a college, what you have is a dying college.

On the other hand, where trust flourishes, learning and teaching flourish. That is the kind of environment I want for myself and my students, and so that’s where my work begins.

Three things I learned at ScreencastCamp

Last week, I had the chance to attend ScreencastCamp, a weekend event put on by Techsmith, Inc. just down M-6 in Okemos, Michigan. What a great experience! Techsmith develops Camtasia, my go-to software for all screencasting needs, as well as several other great products like Jing and SnagIt. I’ve been a fan of their products for a long time, and it was great to spend time getting to know the people behind them.

ScreencastCamp was an unconference, where there is no set agenda beforehand. Participants just come with an idea of what they want to learn, and then either put on a session or request one. There were about 40 of us participating, mostly from education but with a healthy contingent from the corporate (training) world as well. Amazingly, although this is a relatively small number of participants, all the session slots for Saturday and Sunday filled up almost immediately as people pencilled themselves in to give sessions. It was busy. Some of the sessions were like regular conference talks, while others ended up as discussions among four or five like-minded people sitting around on the sofas in a back area of Techsmith headquarters. The hosts were generous, the food (and the beer!) amazing, and the atmosphere of enthusiasm infectious.

I came away with a lot of great ideas about screencasting, but here are the three that stood out the most.

1. Write careful and complete scripts for your screencasts. Back in my series of “How I Do Screencasting” posts, I wrote that a rough script was the way to go. Now I’m a believer in complete, careful, tightly-written and -edited scripts. What’s so great about a complete script? First of all, I have a tendency to talk fast and speed up as I get going in a screencast. Scripting out what I’m going to say not only helps me to edit my thoughts down to just the essential ideas, it also provides a way to talk at a normal, relaxed pace. Second, having a script printed out in front of me will make it easier to caption my videos, which is something that I want to start doing and indeed may eventually have to do. If I have a script, I can copy and paste the text of my screencast into Camtasia for the captions. It’s a little more complicated than that sounds, but at least I wouldn’t have to transcribe the audio.

Techsmith gave us a copy of the template (MS Word, 66 Kb with a bunch of my own stuff on it) they use for their own screencast scripts. I’ve used this simple form for a series of Maple 15 screencasts I’m working on right now, and it’s really made things go a lot more smoothly than when I was reading from a text file, or making it up as I go.

2. Record your audio first, then your video. This was the most radical idea I heard. I had always recorded the audio and the video simultaneously using Camtasia, but that’s not how Techsmith themselves do it. After writing the script, Techsmith screencasters will read the script and record the audio using Audacity. Then the audio file gets exported into Camtasia as an audio track, and the video part is recorded on top of the audio separately. At first I was very skeptical of this (wouldn’t it be a lot more work?) but after trying it myself, I’m a convert. Recording the audio separately reduces cognitive load — you don’t have to worry about getting both the audio and the video right at the same time — and so both pieces turn out better. Audio is much easier to edit when it’s not attached at the hip to video, I think. And you can focus on the quality of the audio as well. As one Techsmith employee put it, viewers will put up with crappy video as long as the audio is good, but not vice versa.

The way I’ve made this work for me is with the following workflow. First, write a good script using the Techsmith template. Then, read the script into Audacity, putting plenty of “white space” in between each box in the template — this gives viewers a little breathing room while they are watching. Next, go back and edit out any mistakes in the audio, either in Audacity or in Camtasia after the audio has been exported. Then, to record the video, turn off all audio inputs (because you’ve already done the audio), start recording the screen, then start the playback of the audio track and just click along with whatever it is you’re saying from the script. After all, this is what your viewers are going to have to do. Once you’re finished, it’s relatively simple to sync up the audio and video (especially if you keep the whole thing short) by just moving the tracks up and down the Camtasia timeline until it looks like they work. Then trim off the beginning and end of the video to make the video and audio the same length.

3. Get a real microphone. I’ve mentioned before that I’m too cheap to buy a USB microphone when the built-in mic on my Macbook works passably well. But after trying some of the higher-end equipment at Techsmith and hearing what it sounds like on playback, I think I might have to be, well, less cheap. When I recorded my practice screencast in the Techsmith studio, the mic captured the full range of my voice without sounding like I was at the bottom of a well, and no other sound made it into the audio. Part of that is because I was in a studio, as opposed to my office, but part of it is the microphone. It really does make a difference.

I also picked up a ton of little tricks and tips from participants — for example, buy a dog clicker to use when you make a mistake on the audio; the spike it makes in the audio waveform is really clear and it makes it easy to find where you need to edit.

ScreencastCamp was a great experience — amazingly, it was totally free too — and I learned a great deal about how to be a better screencaster. Thanks Techsmith!

Changes coming for Casting Out Nines!

Photo by adam*b, http://www.flickr.com/photos/atbartlett/

My family and I are all settled (well, mostly) here in Michigan, and pretty soon I’ll be in full swing in my new position at Grand Valley State University. I can’t overstate what a delight it’s been, getting situated at GVSU. It is a dynamic and forward-thinking university full of great people and exciting ideas. I haven’t met a single person who isn’t excellent at what they do and generous with their expertise.

I am officially taking CO9s off hiatus, and I intend to pick up the pace on blogging as the semester kicks off. That seems wrong — shouldn’t I blog more when it’s less busy? — but I’ve always seen blogging as both an overflow mechanism (to think more about what I’m doing) and an incubator (to kick off new things by rehearsing them here).

Along with a return to regular posting, I have an announcement that I’ve been waiting a long time to make. Over the next few weeks, Casting Out Nines will be rolled into the blog network of the Chronicle of Higher Education, the leading publication about higher ed in the world. Most higher ed people are already familiar with the Chronicle’s print and online publications. The Chronicle Blog Network will be a new venue of voices on the web, writing about higher education, with a worldwide scope and featuring bloggers from all corners of academia.Currently there are two excellent blogs in the network — Tenured Radical and The Ubiquitous Librarian. Casting Out Nines will be joining them.

Posts from blogs in the network will be promoted to Chronicle readers through the Chronicle’s home page, their e-newsletter, and their social media channels. When you take into account that the Chronicle’s website reaches 1.7 million unique visitors and has 14.3 million page views per month, this means that the posts here will be reaching a much, much larger audience than in the past.

Obviously I am tremendously excited about this. This has been in the works for a long time (almost a year?), and things are ready to take shape now. Over the next few weeks, content from the site will be archived and ported over to a new location hosted by the Chronicle on their servers. It will be a hosted WordPress site, which will allow me to add a considerable number of elements to the site that WordPress.com doesn’t currently allow, like different video formats and MathJax typesetting. And I won’t have to deal with technical difficulties. (Although I am not getting any money for this, I consider having a team of experts handling the technical end of things to be more than enough compensation.)

Eventually, when you type in the usual URL for this site, you will be redirected to the new site on the Chronicle’s servers. This means you won’t need to change any web bookmarks you use to get here. As far as RSS feeds go, you might need to change the address. I’m not certain how this will go. Keep your current RSS feed and if it “goes dark” all of a sudden, check back in on the main site; if it’s been officially moved, there will be an RSS subscription link at the new place you can use to replace the old one.

I should stress that although CO9’s will be officially a Chronicle blog, the Chronicle will NOT be editing my work or telling me what to write about or not write about. Also, none of the blogs in the network will be behind the Chronicle’s paywall. The posts you get and the way in which you get them will be the same as always (hopefully the posts will improve in quality…). But you’ll be among potentially a whole lot more readers and commenters, the whole look/feel of the experience should be improved, and you’ll be able to put my posts into context with others in the network and with the Chronicle itself.

It would be wrong not to say a huge thank-you to all of you. (Bonus points if you can remember the blog when it was called something else… and what that “something else” was.) I hope you stick around for the next iteration.

Taking a break

Image via Wikipedia

It’s been pretty quiet around here at Casting Out Nines lately. This is mainly due to two things. First, I’m spending five days a week home with my oldest two kids — the youngest joins us on Wednesdays — and keeping the kids active and engaged doesn’t leave much time for blogging. Second, as you all know, I’m starting a new position at Grand Valley State University in the fall and our big move to Michigan takes place in two weeks. We’re totally uprooting in this move, and preparing for it consumes a lot of time and emotional energy.

I’ve decided that, in light of all this, that I might as well declare the blog to be on hiatus for a month or so until we’re settled. There are a couple of posts that might go up soon — one of them being the last entry in the How I make screencasts series — but otherwise let’s just call it summer vacation here at CO9’s, and things will resume in “back to school” mode later. (“Back to school” time always seems to happen too soon, but that’s another story.)

I do want to mention, because it’s hard to keep it in, that there are some major changes coming up for Casting Out Nines that I am very excited about. These have been brewing for almost a year now and are just about ready to go into place. I can’t really go into detail — nor do I have an exact timetable — but suffice to say that the experience you get here at CO9’s will be better than ever, and it’s more than just another change in the visual theme.

Anyway, that’s it from me for now — follow me on Twitter if you just can’t live without my content (ahem) but otherwise, get out there and enjoy your summer!

Helping the community with educational technology

Image via Wikipedia

Many people associated with educational technology are driven by a passion for helping students learn using technology in a classroom setting. But I wonder if many ed tech people — either researchers or rank-and-file teachers who teach with technology — ever consider a slightly different role, voiced here by Seymour Papert:

Many education reforms failed because parents did not understand or could not accept what their children were doing. Remember the New Math? This time there will be many who have not had the personal experience necessary to appreciate fully the multiple ways in which digital media can augment intellectual productivity. The people who do can make a major contribution to the success of the new initiative by helping others in their communities understand the potential. And being helpful will do much more than improve the uses of the computers. The computers could be a catalyst for turning our communities into “learning communities.”

So true. So much of education falls to the immediate family, and yet often there are technological innovations in the classroom which fail to be supported at home for the simple reason that parents and other family members don’t understand the technology. Ed tech people can make a real impact by simply turning their talents toward this issue.

Question for you all in the comments: How? It seems that the ways that ed tech people use to communicate their thoughts are exactly the ones off the radar screen of the people who need the  most help — Twitter, blogs, conference talks, YouTube videos, etc. You would need to get on the level with the parent trying to help their kid in a medium that they, the parents, understand. How is that best done? Newsletters? Phone hotlines? Take-home fact and instruction sheets? Give me some ideas here.

How I make screencasts: The whiteboard screencast

In this post, the fifth in a series of posts on how I make screencasts, I’m going to focus on what I call the “whiteboard” screencast. This is a screencast where I am demoing some sort of concept or calculation by writing things down, rather than clicking through a Keynote presentation or typing something on the screen. It’s intended to mimic the live presentation of content on a whiteboard, hence my name for it.

Of course the most well-known examples of “whiteboard” screencasts are the videos at Khan Academy. In the unlikely event you haven’t seen a Khan Academy video before, here’s one:

I do whiteboard screencasts fairly often. I use them sometimes for presenting hand calculations for students to watch and work through before class, and sometimes (probably more frequently) I use them to create additional examples for things I’ve covered in class. This is a really powerful use of screencasts — students often want more examples than there is time for in a class meeting, and whiteboard screencasts give me a way to give students as many examples as they can dream up.

The basic principles of whiteboard screencasts are the same as for other screencasts. You first have to engage in basic planning, which involves defining a tight and coherent scope for your screencast and writing out a script. For whiteboard screencasting, which is more free-form than lecture capture using Keynote or PowerPoint, the scripting process has to be a little more rigorous. Because it’s easy for me to get carried away when talking about something that matters to me, I find it very helpful to work out in advance everything that I am going to do in the screencast, in the order and position on the screen that I intend to do it. I don’t always read words from a script, but in order to make the screencast logical and coherent, I do storyboard what I am going to do and practice with the drawings, erasures, and such. Very little of what I do in a whiteboard screencast is ad-libbed. (If I were better at ad-libbing, that might be different.)

So I will start a whiteboard screencast with something like a mind-map of the topic or topics I intend to address and one, maybe two, examples of that topic. Additional topics go into additional screencasts. I work those examples all the way through to ensure that there are no math or other mistakes and that I don’t get stuck in one of my own calculations. If you think about it, this is just the same kind of planning that goes into a successful whiteboard lecture, so this process is not entirely alien to instructors.

Once the screencast is properly planned, it’s time to put it together. This is where it gets technically somewhat complicated. But a lot of people ask me about the tools I use to make whiteboard screencasts, so hopefully this will be worth it. I use four main tools for doing whiteboard screencasts:

• Keynote; I’ll explain in a minute.
• Camtasia, which we saw in the last post in this series.
• FlySketch, a software app from Flying Meat (they also make the popular personal wiki software VoodooPad). FlySketch puts a transparent overlay on top of any existing objects on your computer screen and allows you to draw freehand, draw geometric shapes, or type text on the overlay. See the link for screenshots and a more detailed description.
• A Wacom pen tablet. I currently a Wacom Graphire tablet purchased with a grant a few years ago. With my upcoming job change, I have to hand that in when I leave, so I plan on picking up a Bamboo Pen & Touch this fall.

With those tools, here is the workflow I follow for making a whiteboard screencast.

First, open up Keynote and make a single, blank white slide. This is going to be the “whiteboard” itself. Of course you could also use a blank MS Word document, or any other blank white window or screen. Keynote is just for convenience’s sake.

Next, open up FlySketch and lay it completely over the blank window so that the controls are showing above the top of the window:

Then, open Camtasia and create a custom region that encompasses the “whiteboard”. When the video rolls, it will record what is happening on the whiteboard:

And finally — start the video, and start writing on the FlySketch overlay using the Wacom tablet. Before you start recording, make sure to select the pen color and size you want. If you need to change color, size, or pen type during the screencast — say, you want to switch from freehand writing to typing, or drawing a straight line for an axis — you can tap on the appropriate FlySketch control and Camtasia won’t record it because it’s off-screen.

Then you simply record what you need, then stop, and process the video as was described in the previous post in this series. This includes editing out any mistakes and splicing together multiple video clips for the same screencast.

Here’s an example of the finished product:

Although Sal Khan has been my inspiration for doing screencasts, I’ve made some conscious decisions here to do things differently than Khan does. First, I prefer the white background to the black; it’s more familiar to learners and seems cleaner. I also tend to use thicker pen “tips” than Khan does; I tend to think his pens look a little spidery. Also, the Wacom tablet pen is pressure-sensitive, and that feature works better if the pen tip is thicker. Finally, from a planning perspective, my whiteboard screencasts are a lot less conversational than Khan’s videos. Khan tends to shoot from the hip in terms of presentation; this is part of what makes his videos so charming, but I think it also tends to make his videos go longer than they need to. I prefer to make things a bit more efficient and focused and take less time. It also cuts down on mistakes.

I think the hardest part of this process, for me, was mastering the art of writing on the Wacom tablet in one place and having the writing appear on the screen. This is harder than it sounds! At first my handwriting was horrible (I think at the time I likened it to somebody with a brain injury) but eventually I got my act together. I suspect people learning to play the drums or the piano have to go through the same process before it sounds any good.

Another challenge is managing the relatively small amount of physical space you are working with. A Keynote slide is just not a very large place, and it’s easy to run out of room when writing. If this happens, it can be dealt with by just starting another slide and creating a new video clip. But it’s better for the learner to see one example per slide if possible, and making sure this happens is part of that all-important planning process. I find it helpful to practice the presentation not on the screen or a piece of paper but on a 3 x 5 inch notecard, which has something much closer the same proportions for writing as the Keynote slide on the screen. But note that it does take practice — if you just sit down and try to bang out a whiteboard screencast, it’s likely not to be as good or as instructional as possible, and it could end up taking more time in terms of edits and re-takes than it would if you just planned and practiced in the first place.

I’d be interested in hearing any alternative approaches for making these kinds of screencasts. I once wrote Sal Khan and asked him what his tools were, but never got a response, so I just reverse-engineered what he was doing. There may be a better way. Let me know!

Next up will be the final installment in this series, touching on what I called a “demo” screencast. It’s probably what I do the most. Stay tuned!

How I make screencasts: Lecture capture, part 2

Now that school’s out, I’m going to pick up where I left off (two months ago!) in my series on how I make screencasts. So far I’ve made three posts in this series. In the first post we talked about what a screencast is, exactly, and why anybody would want to make one. In the second post, we saw how the elements of careful planning make screencasting a successful experience. And in the most recent post, we took a look at using Keynote (or PowerPoint) to create a lecture-capture screencast.

Before I talk about the other kinds of screencasts I make, I’m going to take this post to describe how I use my go-to tool for screencasting: Camtasia for Mac, specifically how I use it to make lecture capture videos when I’m not using Keynote. (Full disclosure: I was on the beta-testing team for Camtasia for Mac and got a free license for the software for my efforts. But I can definitely say that I’d gladly have paid the $99 for the software otherwise — it’s that useful.) There is a Windows version of Camtasia and a server-oriented variant called Camtasia Relay, and they are all very similar, so what I describe in this post can be used if lots of different situations.

Let’s suppose I have a lecture or presentation that I want to turn into a screencast, which basically means I need to record the presentation as it happens on the screen and add a voice-over. I’ve already described how to do this with Keynote or PowerPoint, but what if you’re using Prezi, Beamer, or some other presentation tool? What I need is a tool that will record stuff happening on the screen that’s separate from the presentation tool itself. That’s where Camtasia comes in.

Camtasia is software that records video of anything happening on your screen — all of it, or part of it — along with any audio you choose to add, including voiceovers. You can record multiple segments of video, edit those segments, and put it all together with transitions and effects. The interface is laid out a lot like iMovie, so Mac users will feel right at home using it.

There are a lot — seriously, a lot — of options for working with video in Camtasia, too many to get into here. I’ll just show an example of a simple lecture capture putting Prezi and Camtasia together.

First, bring up the screen that has the Prezi in it. (For Prezis particularly, creating the lecture capture works best if you download the Prezi to your local drive and then run it in a window, rather than trying to run it on the web.)

Now launch Camtasia. When you do, a little floating pane will come up that looks like this:

The dropdown menu on the left lets you specify which part of the screen you’re going to capture. I usually just select “YouTube HD/720p”, which records essentially the entire screen. I can crop out what I don’t need later. And once I put it on YouTube (which is my usual destination for screencasts) it’ll be in glorious 720p HD.

Once you’ve selected your area, just click the Record button and start presenting, just as you would if you were giving the lecture in front of a live audience. Your lecture is being recorded behind the scenes and all you see is your screen. Warning: Presenting for a screencast feels a lot different than doing it for a live audience because, well, the audience isn’t there. There’s no body language or ambience to add to the presentation. So this will feel a little unusual at first. Also, I can’t stress enough that you should probably go from a prepared script the first few times you do this, rather than try to wing it. It’ll keep you on track and prevent lots of mistakes.

When you stop recording, you’re brought into the main editing area of Camtasia:

The bottom part of this screen is called the “timeline”. Right now, the one clip that I have in the timeline is a partial video of the presentation. It appears as a chunk of the timeline outlined in blue. Inside the timeline you can see the audio levels given as waveforms, and there’s a playhead along the top of the timeline showing you where you are in the video as well as the time.

At this point, what I usually do is check the sound levels first. A lot of times the built-in microphone on my Macbook doesn’t record very loudly. I’ll listen to a bit of the recorded video to check if that is the case. If so, I go and apply the Dynamics Processor effect to the clip I made:

You apply the clip just by dragging it from the effects area directly onto the clip in the timeline. In fact this is how all the effects, transitions, and other features of Camtasia are applied to video. The Dynamics Processor brings all audio levels up to a uniformly audible setting.

If I have the time, I will watch the whole video from start to finish to see if I’m happy with it. If there’s something I need to edit out — I goofed the script, or sneezed, or the phone rang, etc. — I can go back and edit that part out just by putting the playhead just before the mistake:

Then selecting “Split selected at playhead” from the Edit menu; this splits the video clip in two, right where the blooper is. Then move the playhead until just after the mistake, and selecting “Trim Start to Playhead”. This will crop out the blooper from the second clip. Then you can just drag the second clip over next to the first one, and with that, the blooper is edited out.

The ability to edit in such an easy way really changed screencasting for me. You will make mistakes when you screencast, no matter how good or experienced you get. But you don’t want to have to throw away an entire screencast because of one goof. If I am screencasting and I make a mistake, I just pause for a moment, and then I start again from the point of error. The pause will show up on the audio as a flat spot, and I can go back and edit the error out. You cannot do this with the voiceover features of Keynote and PowerPoint, and it makes a huge difference.

If this is just a straight lecture capture — so there’s no other video coming in from a different source — at this point I’m done. The only thing left to do is add the “credits page” that I always put at the end of my screencasts that lists my email, YouTube channel, Twitter, and so on. I have this saved as a PDF. To bring it into the timeline, I go to Import Media:

and select it from the file finder. It then appears as a clip:

I just drag it into the timeline at the end of the video:

And then, for effect, add a fade-in transition from the video to the credits, which I do by finding it in the transitions menu:

And dragging and dropping it in the little seam between the video clip and the credits page:

Now I’m ready to publish. Camtasia allows me to publish the resulting video directly to my YouTube channel using the Share menu:

As you can see, there are options for iTunes and Screencast.com as well. Or you can just choose “Export…” which exports the video to a file format of your choice, for uploading wherever you want.

After I start the process, Camtasia converts the video to Quicktime and then uploads it with the title I gave it. A 10-minute video will take several minutes to complete this process on a Macbook Pro. Your mileage will vary according to your system hardware and your internet connection. After it’s done uploading, I still have to go to YouTube and add metadata. But otherwise that’s it!

What’s nice about Camtasia is that the tool is separate from the presentation tool you’re using. So if you already have the presentation content made up, you can turn it into a screencast quite easily. It doesn’t matter whether it’s Prezi, Beamer, a text document you’re scrolling down, or anything else. And the more you do this, the easier it gets to convert existing presentation content into a mobile device-friendly screencast.

In the next post, I’ll talk about what I call “whiteboard” screencasts, where I record stuff that I am writing on the screen. This is a lot like what Salman Khan at Khan Academy does. Hopefully it won’t be another two months before I get to that.
