[unity]

Dear eumagga0x2a you are not answering again
(I had to create a separate topic)

I'm really looking forward to your response to other points.
"I'll try to comment on further requests later."
I will repeat from (also just in case)

""""
2) "Do you mean automatically adding multiple external audio tracks for each source video?"

yes, how can this be implemented? through names - language postfix - audio track?

-----------------------
here is an example of a specific technical task - batch conversion -
there are, say, 100 videos
1) batch extraction of audio tracks (video remains without sound)
2) add -to these 100 videos (now without sound - after 1 step)
several audio tracks for each video (in different languages, and the number of added audio tracks should be controlled (in the script?), from two to (how many are possible in ?
"For a list of valid language descriptors, see
github"

how can this be implemented? through names - language postfix - audio track?
-----------------------------------
and tell me if it is possible to create a batch conversion (also 100 video files),
video file - with two audio tracks in different languages, audio track01 (in one language) in, say, the left audio channel (L), and audio track02 (in another language) in, say, the right audio channel (R)?
Thank you!
