Other than that, frames perfectly match (if we ignore the fact resolution is different).

Both video streams are at 25 FPS but B contains a duplicate frame every 24 frames (it's probably the result of a 24 to 25 FPS conversion). I would like to transfer subtitles from A to B. another mkv file (let's call it B) with video and audio also synchronized but without subtitles.īoth files are the showing same content but with different video/audio quality (B is much better than A).a mkv file (let's call it A) with video, audio and subtitles correctly synchronized.
