Answer 1

assuming you mean screen cast without sound, then you could take a screen capture at a rate of 30 pictures per seconds then put that in a vector, create a video of that and use a good encoder so you dont waste to much memory

mp4 uses H.264/x264 and works very good but you can use whatever you want...
