How to transcode MKV to MP4 (change containers without recoding) and preserve subtitles and chapters

May 10 at 4:12 AM
Here's a great way to use MCEBuddy to transcode MKV files to MP4 files automatically using the power of MCEBuddy to batch process.
  1. Create a Monitor Task with the following settings
    a. Set the Monitor Path to your folder full of MKV (or mixed) files.__
    b. Set the Search Pattern to *.MKV in the Monitor Task.
    c. (Optionally) select the option to Delete Original File in the Expert Settings page if you don't want to keep the original MKV file after transcoding to MP4.
  2. Create a Conversion Task with the following settings
    a. Profile -> MP4 Unprocessed (we will come back to this later)
    b. Destination -> <blank> (leaving it blank will place the transcoded file in the original directory)
    c. Ad remover -> Select None
    d. Uncheck Rename and sort by video information
    e. (Optionally) check Extract subtitles and closed captions if you want to preserve any subtitle tracks
    f. Click on Expert Settings
    g. (Optionally) uncheck Download information if you don't want MCEBuddy to download additional metadata from the internet (speeds it up)
    h. (Optionally) uncheck Add information if you won't want MCEBuddy to add the metadata to the transcoded MP4 file (speeds it up)
    i. (Optionally) check Add subtitles and chapters if you want MCEBuddy to add the subtitle tracks and chapters (either from SRT files or those extracted from the MKV file) to the MP4 file
    j. Check Skip remuxing files (don't forget this)
Coming back to 2.a, open the file profiles.conf in the MCEBuddy installation directory under the Config folder. Look for the profile MP4 Unprocessed. In that profile remove -ss 3 from the ffmpeg-video line, i.e. replace
ffmpeg-video=-ss 3 -vcodec copy -sn
ffmpeg-video=-vcodec copy -sn
If you forget this step, MCEBuddy will skip the first 3 seconds of the file while transcoding it from MKV to MP4.

Save the file profiles.conf, Click Start on the MCEBuddy application and you're Done!!

Enjoy a totally seamless hasslefree automated conversion of your library from MKV to MP4 while Optionally preserving your chapters and subtitles.
