Good day! I'm looking for MKVToolNix equivalent software for .MP4's. I will use it in a video file without subtitles, I'll find it's subtitle and merge it with the video file just like what I did in MKVToolNix. Thanks!

  • I needed the same thing. I couldnt find, and contacted them, and asked to add ability to "bake" the result in "mp4" too, not only in mkv.. – T.Todua Aug 2 '17 at 10:27
  • waiting their answer.. till that, i've found nice topic here - forum.videohelp.com/threads/… – T.Todua Aug 2 '17 at 10:41

Muxing a file simply means to extract individual streams out of existing container files or mix existing streams together into a new container file. For MP4, this can be done with ffmpeg and the -c copy switch. If you don't want to write command line inputs, XMedia Recode is a good, free GUI for ffmpeg. There's a documentation on the website, simply select Direct Stream Copy to avoid reencoding the individual streams.

  • Can you point me to where is Direct Stream Copy? Can't find that function you're mentioning. Thanks! – Julius Alfeche Mar 16 '17 at 4:13
  • @JuliusAlfeche That exact phrase was taken from the website (see link). To copy a stream instead of converting it, load a file in the program, open the respective tab (video/audio) and set the Mode dropdown to Copy – MoritzLost Mar 16 '17 at 12:46

dmMediaConverter is very similar to MKVToolnix.

It is just a ffmpeg gui, so it can save in any format.

enter image description here

To replicate the described MKVToolnix use, select "Convert", then "Add files", selecting both video and subtitles.

Check "Enabled" to keep the stream, uncheck to remove it.

Check "Copy" to keep the stream as it is, uncheck to trasnscode it.
