I want to create an archive of 720p-1080p video collection. My mother tongue is Turkish, that's why I archive my films as DUAL releases which both contain Turkish and English sound streams. I sometimes download the normal releases and find the proper sound for the film. The problem is, Turkish sound stream sometimes contains 2/0 channels, which I dont prefer because 5.1 sound is far better than 2.0
I read that those 2/0 streams can be converted to 3/2/1 by
demuxing original 5.1 audio stream into 1-by-1 channels
encoding the stereo dubbed sound to mono channel wav
replacing the mono sound with center channel of 5.1
re-ripping the new channels to 5.1
I need your help on how to do this. I tried using besweet but it was the most complicated program ever I have used.
