NOTE: Project has been renamed to dem2video due to upcoming various codecs support.
I'm looking for developers at the moment. Personally I can spent little time on this project, but there are a lot of features needed to be done. Many people asking about win32 porting. I have no Windows installed on my box, so it's almost impossible to me :) Next, OpenGL support, sound writing support, Quake2 demos support etc. If you can help, feel free to contact me.
Also, take a look on similar project of Anthony Bailey, QuakeCapture . This is a patch for Quake I/II sources which adds a new commands for video exporting. So any Quake port maintainer can easily apply it on own engine. Now it has video support only for Win32, but we're working on cross-platform video out.
