Thanks. And belcampo's suggestion to output a raw .h264 file using MP4Box
gets me halfway there. When I tell mencoder to encode the .h264 file
generated by MP4Box, the picture quality is excellent, but the motion is all
messed up, presumably because I don't know how to tell mencoder what frames
and frame rate to use. If you could shed light on that situation, that would
also be welcome. Thanks again.
