I muxed 2 files properly, but the audio track was bigger (Atmos) than the original ( DD5.1). Would the Atmos file be off in tracking regardless because it's bigger? It's ahead by a second or two. How do I roll back the audio with MKV?

If "bigger" means the file size is bigger, that doesn't matter. If you mean the running time is longer that could be a problem.

Use the "Delay (in ms):" field to delay an audio track. If the audio track needs to be advanced use a negative delay.

Yes bigger as in the 2 audio tracks Atmos/DD5.1 is bigger in size. The run time is the same. Ok I will try that. I do that before I mux? Does that I mean have to keep "remuxxing" with 1-2-3..etc different settings to get a track right? I tried Project Meterorite (no good). I appreciate your help. Thanks.

You can use a media player that lets you open a different audio track and also lets you advance/delay the audio relative to the video. MPCHC, MPCBE, VLC, all the advanced media players have this.

Yes I use MPC-HC. I tried "VSync". I do not know where to go?

IN options Playback/sync render settings ? That's a bit complicated for me. Mine is greyed out too. If that's the right area?Thanks

+ and - on the keypad

Don't know what +/- refers to? I do know that nothing works inside that window (like I said all grey). I appreciate your help. Too big for me. I am moving on. Thanks

While the video is playing press + (advance audio) or - (delay audio) keys on the numeric keypad of your keyboard.
