Software to record myself sleeping I've been going crazy in my sleep lately, or so it would seem--I wake up with my sheets all over the place, my phone on the other side of the room (normally it's next to my pillow), etc. I'd like to record myself sleeping too see what's going on. Is there any software that would be good for this?

I obviously don't want or need 8 hours of 1080p 60fps footage, just something that would give me an idea of what the hell I'm doing. (I'm thinking snapshots every 3 seconds?) I don't need motion detection; I'd like to capture whether I'm moving or not. I can use my PC webcam; I have a face cover thing so I can sleep with the lights bright enough to record. I also have an internal 1TB HDD that's empty and available for storing the footage.

Any suggestions for good free software that I can use? (Heck, is it possible with VLC?)
