Ive got 2 copies of a certain movie.
the other one is from Japan, the other one is from US.
both are 23.976 fps
The Japanese copy has a better video quality and I want to mux the US audio to it.
The problem is it doesn't sync starting from maybe 1/3, and more noticeable nearly at the end of the movie.
Upon investigating I noticed that the Japanese video comes with more frames (150 frames).
I looked further into it on where it came from (hopefully I can find it as a clump of consecutive frames),
but the unexpected part is... the extra frames are scattered all through out the whole movie,
specifically 1 extra frames every 800-1200 frames.
its pain in the ass to search for those frames and remove them one by one (so the audio will sync).
So i came up thinking an audio stretch as last resort so it will accommodate the 150 frames on the japanese video.
can i do that on ffmpeg? if yes, can someone help me with the command line?
Anyway, my audio is already on wav form.
thanks and have a nice day...
