I'm glad it worked out for you!
How to demux a video stream from a video file and combine it later with unaltered audio
The principles are the same, but this time you'll have to use MKVToolnix and Handbrake.
(which was linked to in our previous posts)
Since you're familiar with the principles of MKVToolnix and Handbrake as suggested by the 1st helper, i'll be more brief this time around.
Steps to follow:-
Example this time is a mkv video file of an episode from the series Revenge.
1) Demux the video from the audio using MKVToolnix; instead of ticking the audio file, you will now tick just the video file and leave the audio file unticked.
2) This time around you want the output file to have an extension of .mkv, as it's the only container supported by MKVToolnix (as the name suggests)
3) Click start muxing and wait while the video file is output
Next step is to convert the video file format to another one of your choice using Handbrake.
4) Open Handbrake
5) Drag the newly created video file (the one without any audio) into Handbrake
6) Choose your preferred video format from the video tab in Handbrake (you should know better than i do which formats your Free Agent Theatre supports)
7) When you're satisfied with the desired codec and quality settings (make sure the settings/profiles are supported by your respective media device), and destination, click the green start button at the top
8) Wait until it's done. (This will take much longer because you are transcoding video this time, audio takes much faster to process than video)
Finally, It's time to combine the two:-
9) Open MKVToolnix again, drag the newly processed mp4/mkv/m4va file you made in Handbrake into MKVToolnix
10) This next step is important; tick the original audio track(s) you want, and also the video track of the video file you dragged into MKVToolnix, don't forget to untick the original video track.
11) Click start muxing and wait for the output to finish.
That's it! You're all done!
Hope that helps!
