Hi all, I have some video files (video only, no audio) that were recorded using ffmpeg to capture a computer screen. Unfortunately, it seems that the frame rate is somehow inconsistent. When I stretch it (almost four minutes overall!) to synchronize over the 38 minutes of the audio file which was captured simultaneously, but on a different machine, the middle part goes way out of sync, drifting ahead and behind at different points. We're not talking a few frames here either, but tens of seconds.
So, I suppose I have two questions, the more important is whether there might be a way to have ffmpeg recreate a fixed frame rate, building in the necessary duplicate frames, or dropping frames, based on the *timestamps* on frames? I will say that I tried simply transcoding from the x264/mp4 original file to a prores_ks/mov file, but the inconsistency was not fixed. The secondary question is what might cause this (it's an x11grab input through libx264, and was using about 2.5 of the 4 cores the machine has.) and how might I know that it's failing while the recording is taking place?
