Not exactly. I accidentally left my Qcam running time lapse and went to
bed last night (I move around a bit in my sleep...) and when I awoke, 200
MB had been chewed up by temp files from QuickMovie. I also noticed that
it writes to disk every n seconds, as if writing a frame.
With enough swap space, you could just buffer it all, then write it out
later, couldn't you? Or does anyone know a way to get around the kernel
buffering and do a direct write? Maybe we should ask God^H^H^HLinus...
