If you don’t want to write command line inputs, XMedia Recode is a good, free GUI for ffmpeg ( only available for Windows ). For MP4, this can be done with ffmpeg and the -c copy switch. Muxing a file simply means to extract individual streams out of existing container files or mix existing streams together into a new container file. If you want to check the effect, press the Play icon on the media player on the right side of the window to preview it. Then navigate to the location that save the subtitle file on popup dialog and open it. My ultimate wish is to be able to have the subtitles show up in Premiere Pro, since thats where Id like to do any cutting, clarification, etc. Step 2: Add subtitles to MKV simply Head to the media library area, select a video file and click on the Plus icon next to the subtitle option. The subtitles will also display in Quicktime, although theyre tiny and I havent been able to enlarge them to a useful size. Sorry, but such a feature will never be implemented in MKVToolNix GUI itself. According to VLC, the subtitles use the tx3g codec. With “batch muxing” users usually mean doing similar steps with a bunch of files without having to create a job for each individual file.

I’d like the GUI to be able to do XYZ automatically on a bunch of files. What do you mean by batch muxing in MKVToolNix? When it’s finished you have a MKV file with copies of your source video and audio inside. A Status and Progress window will appear and show you what’s being done, as well as any warnings or errors in the muxing process. Once you have all the necessary options set for your streams you can use the Start Muxing button to tell mkvmerge to begin. This would also keep the SRT as an SRT and not transcode it into mov_text.

If you aren’t opposed to MKV containers, then there is no reason you can’t just take the input mp4 and separate subtitle file and mux all the streams into a new MKV file instead.

Ĭan you use MKVToolNix for MP4 subtitles? Make sure you are saving the file in the right place & Start Muxing.Open the MKVToolNix application (it may show up as an “mkvmerge” executable on some operating systems):.split by sizes or extract by specific timecodes).

Since MKVToolnix doesn’t actually recode anything, you’re not “converting” anything. You will see the format and other important information of the subtitle file on the bottom window of the app.
