[FFmpeg-devel,3/4. -b:v:0 2M sets the bitrate for the first video stream, while -b:a 128k sets the bitrate for all audio streams. mpg Advanced usage: mkvid-ffmpeg.

Options to adjust: vmax_b_frames: 1 or 2 is good, depending on the movie. Normally, a MOV/MP4 file has all the metadata about all packets stored in one location (written at the end of the file, it can be moved to the start for better playback by adding faststart to the movflags, or using the qt-faststart tool). Mpeg4 support is enabled at compile time, as is libfaad2, but it doesn't recognize m4a files. I need the buffer to be much longer (10 secs). Wherever you download ffmpeg from, execute ffmpeg -formats and make sure that the 'E' flag is set for xvid, mpeg2video and h264 under the Codecs list (signaling that encode is available for those algorithms), and 'E' is set for m4v, m2v and h264 under File Formats (signaling writing to these elementary stream types is available as options).

The first text file is the FFMpeg log of the different length files session and the second is one where both are the same length. One more question: in your experience is there any difference between ffmpeg for Windows & ffmpeg for OS X?. ffmpeg's mpeg2video encoder does not do automatic thread detection, so I set this to 4 because I'm working on a 4-core machine; you could omit this option, but if you're outputting to one or more codecs, and you're using -threads 0 with another codec, ffmpeg will try to use the automatic thread detection on the MPEG-2 output, and it.
