There's plenty of info available on how to create screencapture videos for the Windows and Mac platforms but, what about Linux? Chris Cherrett has come up with a simple (and free) solution...
I have been working on trying to figure out how to create high quality video tutorials based on screen captures in Linux for about two years now. I have tried vncrec and export to xpm then to png. I have tried istanbul, vncswf, raw X captures via bash script, vmware workstation's avi capture function, and a few I have forgot about I am sure :) After all my research and pain I have finally found the solution that is fast flexible and gives great results. It is not Open Source but it is a free download for Linux. You may have heard of it before. Wink is a utility for creating flash/swf based presentations. While experimenting with capturing my screens with it, I found the answer I was looking for.
1. Using Wink, capture your video and then stop capture.
2. Wink loads the video into it's editor.
3. Instead of rendering the video as an swf file, select File->Export as HTML.
4. Name your html file and select your image output format.
5. Click OK.
You now have a sequence of crystal clear PNGs, or whatever format you selected, ready for editing in the Blender Sequencer!
It is just that easy!
P.S. - Load the images as an image sequence in the Compositor and now you can overlay a sound track. :)
Wink is a Tutorial and Presentation creation software, primarily aimed at creating tutorials on how to use software. Using Wink, you can capture screenshots, add explanations boxes, buttons, titles, etc. and generate a highly effective tutorial for your users.
