(being a newbie to encoding), why would you suggest ffmpeg and not x264
to do the encoding.

I recently went through the process of trying to encode some avi files,
that would not play with mplayer or mencoder (it would bomb out), I had
to use transcode with import lav not ffmpeg (just realised i could have
probably done the same with mencoder) export to yuv4mpeg and then
process with x264, process the audio and then merge back together with
MP4Box

Is there any time frame on when mencoder will be able to handle mp4
files directly ?
