I demux the Atmos track from 4K UHD Titanic 1997 and I want to remux to my existing Titanic 3D iso , I can successfully put the track on Disc 1 , but for disc 2 how can I cut the 3hours long .ac3 to specific time for Disc 2 ? I tried to use the split and cut function on tsMuxer , but when I put the already cut track to it , when I test it the track is like super super fast forward and unable to use , any help ? Thx
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

First, have you tried latest nightly build of tsMuxer?
Maybe mkvmerge does a better job splitting Atmos. You can try with MKVToolNix GUI. -
You can try clever FFmpeg-GUI.
Load your movie WITH the atmos track, click main, click cut, waint until indexing has finished, set your cut time, click check times and finally click cut.
The cut is done at the nearest keyframe, so it's not frame accurate.

Click source file, then drag and drop the new cutted piece, click main. click extract streams, select the atmos track on the left and click extract.

Tested here successfully with an atmos track movie. -

Yes
A moment, you're on a mac?
clever FFmpeg GUI works on Windows only, sorry. -

So remux first your m2ts.
drag & drop it, click main, click multiplex, check if all streams are checked on the left, set mkv as container and click multiplex.
Control if the mkv is in synch at beginning, mid, end.
If so, repeat the cut with the new mkv. -

Multiplexing is the combination of all streams in a container (mp4, mov, mkv, ts, m2ts...).
The question is related to the videostream only, not to the audiostreams.
Select the container as answer. -
[Attachment 75542 - Click to enlarge] Thx , when I use tsMuxeR to remux the extracted Atmos , it show this kind of error , I think this is why the Atmos track is out of sync when I remux it , but I have seen the cutted mkv video, and it is sync in that video ! So what am I doing it wrong ? Thx -

Clever Ffmpeg-GUI can mux to m2ts.
That's all. The rest must be done by other ways. -
