I have been facing a problem while merging two or more cut files from sources of exactly same codec. The problem is the result video has a black screen when the first clip ends. I have tried redoing multiple times and seems it's always the one video clip causing the issue.
I use keyframes to initially clip these files from sources that I later try to merge. Any idea why this happens and any workarounds?
If you have advice for any other tools for lossless mkv merging after cutting from their sources, I'm all ears! Thanks!
