this seems to be a too stupid question, I couldn't find any information on it so far.

I try to capture a video by pressing CTRL-ALT-F5 and the same keys again after a while. There is no beep and no message anywhere, so I don't see if anything happened, and I can't find a video anywhere. The manual pages explain in detail how to capture and play the video but none of them says where the video file actually IS.

Anyone?
