How to Losslessly merge MP4 and SRT into MKV (MKVToolNix GUI) - YouTube. Download MKVToolNix GUI https://www.videohelp.com/software/MKVToolNix.

  • It suports MPEG-4 ASP (xvid), MPEG-4 AVC (x264), AAC, MP2, MP3, Flac, Vorbis, AC3 audio and various common containers support (MP4, MKV, AVI, M2TS). Top Searches mkvtoolnix.
  • Alternatively, go from MP4+SRT to MKV with mkvtoolnix. 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. This would also keep the SRT as an SRT and not transcode it into movtext.

I streamed a few DJ sets over the last few weeks with a bunch of friends as part of ‘covidcore’, an online get-together while we’re all in isolation. It’s been a while since I’ve played any DJ sets but it was great fun and thankfully I didn’t make too many mistakes.

Anyway, It was my first streaming experience and I found it a breeze to set up thanks to Twitch and OBS. When reviewing my recordings I noticed that my microphone level was pretty low so I decided to bust out the audio track from the video and raise it. Also when uploading my video to Youtube I also got a copyright notice about one the clips in my video which was subsequently being blocked, so I decided to edit that out too.

Here is how you can do it.

Note: I’m on a mac so all of the instructions are for that, but apart from installation the rest should be platform agnostic.

Steps

Mkvtoolnix Convert To Mp4

  • Install mkvtoolnix
  • Extract audio and video tracks from mkv file
  • Optionally convert audio track if editing needed
  • Merge audio and video tracks back in to mkv file

Install mkvtoolnix

mkvtoolnix is a set of command line programs for finding out information and modifying mkv (“Matroska”) files. You can install it with a GUI but I didn’t bother.

That’s it, boom!

Extract audio and video tracks from mkv file

For this step we are going to run this command

In the above command we are using mkvextract, part of mkvtoolnix, to extract the video track which is encoded using the ‘h264’ codec and also the audio track which is encoded using the AAC codec.

In order to find out what your video and audio tracks were encoded with use the following tool

Might be good to reference the docs if you have trouble there.

Optionally convert audio track if editing needed

My audio editor couldn’t open the aac file I created so I converted it to FLAC format using ffmpeg, another command line program that is insanely useful for converting audio formats (amongst other things).

So to convert I ran

Now I can open my flac file and edit the parts I want, like amplifying my microphone in the recording.

Mkvtoolnix Merge Mkv

Merge audio and video tracks back in to mkv file

Convert Mkv To Mp4 Using Mkvtoolnix

Right, now you have completed your editing we can stitch them back together again using the mkvmerge command

Mp4 Toolnix

You can see I just merged the flac formatted audio back in. I just tried it and it worked. I need to read up a bit more on file formats to be honest so if you need more info check the docs.
