I have been trying to fix a frame rate problem I got. I had an mp4 at the wrong rate for my t.v. It was at 30fps and my tv wants 25fps it seems. I got it changed with ffmpeg but the audio is out of sync. There's suggestions for how to get it back but they seem to be suggestions for changing a fixed discrepancy in time. I think this problem is not linear like that but the thing goes increasingly out of sync as the video plays. So I've just thought to start from the beginning and query the community again maybe.
I don't know that's going to help at all but that's what I'm doing here. the beginning was a matroska mkv file.and here's what ffprobe says about it: Input #0, matroska,webm, from 'ACPOTBEGIN.MKV': Metadata: ENCODER : Lavf58.29.100 Duration: 00:25:43.27, start: 0.000000, bitrate: 931 kb/s Stream #0:0(eng): Video: vp9 (Profile 0), yuv420p(tv, bt709), 1280x720, SAR 1:1 DAR 16:9, 30 fps, 30 tbr, 1k tbn, 1k tbc (default) Metadata: DURATION : 00:25:43.156000000 Stream #0:1(eng): Audio: aac (LC), 44100 Hz, stereo, fltp (default) Metadata: HANDLER_NAME : SoundHandler ENCODER : Lavc58.54.100 aac DURATION : 00:25:43.267000000 Any ideas how to get from there to a good file at 25fps? :) ------------------------------------- Remember Brandolini's Law and look around. _______________________________________________ ffmpeg-user mailing list email@example.com https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
