You'll want aspect=4/3 to make the picture non-horrendous. Also, with movies and animation, you'll want pullup before your deinterlacer at a minimum. Sooner or later you'll discover setting a bitrate is a bad idea, as a fast scene leaves the video looking horrible for *minutes*. vqscale can work, or perhaps a very large large vratetol=. > Is there anything to be gained by capturing in MJPEG or raw > format then doing a 2-pass MPEG conversion offline ? Plenty. See pullup vs. interlacing (can't always be guessed before-hand), and much higher quality at a given bitrate thanks to 2-pass, and other quality-improving options like mbd=2:trell, etc., etc. which your PC may not be fast enough to do in realtime. -- Ha. I'm the idiot.
