    Until recently I had been able to use Quicktime 7 to perform a passthrough encode of MKV to MP4. Meaning there is no need to re-encode audio/video.

    This means you can convert an hour long MKV file via pass through encode to MP4 in about 30 seconds instead of having to use something like Handbrake to do the same thing and having it take 30-35 minutes.

    Quicktime 7 handles it if you have Perian installed.

    It seems like mtn lion is not supporting the last build of Perian so I am looking to see if anyone has a different method for doing this.

    Yes, VLC will do this. You can also use ffmpeg from the command line:

    Code:
    ffmpeg -i input_file.mkv -vcodec copy -acodec copy output_file.mp4
    -vcodec copy and -acodec copy mean to copy the video and audio streams over ("passthrough").
