Let's say you have two sources from the same content.
One is in SD quality and the other in HD.
SD video has an audio track that I need to insert into the HD one.
However if I pause the same moment/frame from a scene in both I discover:
- The SD video frame is located at:
02:00:520
- The HD one is located at:
02:01:502
So what I do is simple: if I am to move tracks from SD to HD I need to inform MKVToolnix to introduce a positive delay of 1000 ms or 1 second.
This in the end makes tracks from #1 in sync with #2, because that's the difference between them.
The problem with this idea is doing this to many videos and using a player like MPC-HC to pause the exact frame/scene in both sources.
How can I open MKV files and others like MP4, AVI, etc. and pause them at the exact same frame/second? Minor differences don't matter, as long as they are at the same spot, so I know how much delay is there.
