Screencasting in Ubuntu

I’ve done my first screencast in Ubuntu using gtk-record My Desktop, a tool that records desktop sessions in Linux. I’ve long wanted to do screencasts in Ubuntu ever since I installed Feisty Fawn or the 7.04 release but I haven’t been successful in my initial attempts.

I first tried capturing desktop sessions into movie files using xvidcap but I couldn’t get it to work properly. All the videos I produced using it were jerky, as if the capture rate is just a frame for every two seconds. I spent days playing around with the settings, to no avail.

I was on the verge of accepting the idea that I may have to use Windows XP and Camstudio to produce screencasts to accompany some of my blog articles when I decided to give gtk-recordMyDesktop a try.

I spotted the program during the days I tried looking for ways to do screencasts in Ubuntu but I just filed it away as something to check later because it produces Ogg-encapsulated Theora-Vorbis files and the free video hosts I wanted to use for screencasts, Vimeo and Revver, do not accept .ogg files. I’m lazy and a non-geek and my impression of video conversions in Linux is that the process is rather complicated. (Blogger’s Note: see update below)

After giving up on making xvidcap, which produces mpeg files, work in my laptop, I tried gtk-recordMyDesktop. I gave it a go after finding out that accepts .ogg files.

New screencast on using a TiddlyWiki

I’ve recreated my earlier video guide on using a TiddlyWiki, a single-page wiki you can use for your notes and task lists. Instead of Wink, I used CamStudio to capture screen activities this time.

Wink is an easy to use free software to capture videos of your screen activities and it’s great for creating tutorials. My only problem with it is that it doesn’t offer an option to capture screen activities in video format (i.e. mpeg or avi) so that it can easily be uploaded in video sharing sites like YouTube, Metacafe, and Revver. Wink outputs the screen activities in .swf and .exe formats.

My previous screencasts– one is on how to turn any web template into a WordPress theme–are in .swf format and hosted in the Internet Archive. I’ve had complaints on its playback quality and how it can be slow at times so I decided to try hosting it other video services. These services, however, do not accept .swf files so I spent days trying one application after another to convert the files into .mpg or .avi formats to no avail.
