Well, sure you can with minimal options (keyint=0 and no vhq), but
it's pointless since the resulting file will be huge (or else horrible
quality) and you'll have to reencode later anyway. On a system like
that it's best to encode with mjpeg or something simple to begin with
and then transcode to mpeg4 later.
