Thinking about it a little bit more, having the -an or removing the -an filter can change the computed duration of the file depending on audio track durations and any start_pts for the tracks. I think ffmpeg prioritized the audio track duration over the video track. I think I saw something recently? So I take my previous advice back and suggest using the audio codec consistently between the first and second pass commands. Also using -fps_mode cfr is the recommended way for newer ffmpeg versions. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
