Any mkv to mp4 batch remuxer?

[SatStorm]

Hi all,

I have many h264/aac files on mkv and I wish to remux them as mp4 so to playback them on virtualdj (it doesn't support mkv files). No encoding, just re-muxing.

Usually, I use avidemux for that, but I was wondering if there are other simply alternatives out there for this, that also allows batch converting!

Thanks in advance!

Xenon MKV will batch convert MKV to MP4, It simply changes the conatainer to MP4, while converting the audio to 2 channel AAC, the video wont be converted.

I don't think it has AAC passthough so it may convert the audio to AAC, even if it is already.

Have you tried a mp4 multiplexer? Maybe MyMP4BoxGUI, yamb or mp4muxer.

Or ffmpeg:

for %a in ("*.mkv") do ffmpeg -i %a -acodec copy -vcodec copy %a.mp4

Save as video.bat in same folder as the mkv files and run the .bat file.

I was going to suggest the same, but the test script I created threw up an error.

Could not write header for output file #0 (incorrect codec parameters ?)

It might be my FFmpeg version or the MKV files I was using. It might still be worth a try though.

I had success only with mp4muxer so far. Fast, makes the files playable on virtualdj!

Thanks Baldrick and mh2360!
