That's my basic plan. Probably some kind of electric eye. The Pi takes a little under two seconds to wind up and actually start recording, but the runs take about three seconds so that should be enough time.

I didn't get a chance to pull the scripts last night but I'm actually curious to see what improvements people might recommend. Really, it's just the command line to ffmpeg that's the key. The rest is just setting a few video4linux2 parameters and playing the resulting file.
