--- Comment #8 from Jean-Baptiste Mardelle <j...@kdenlive.org> --- Detection of VFR clips happens in MLT. Your clips doesn't pass a check comparing FFmpeg's average and real frame rates on the video stream : av_cmp_q(stream->avg_frame_rate, stream->r_frame_rate); https://github.com/mltframework/mlt/blob/master/src/modules/avformat/producer_avformat.c#L1398 If you think this is incorrect, it means that there is a problem within this check or in FFmpeg. However there are several reports of GoPro producing VFR clips, and you can see Dan's answer (the MLT maintainer)on this topic: https://forum.shotcut.org/t/constant-frame-rate-video-incorrectly-determined-to-be-variable-frame-rate-in-20-11-29/25112/3 -- You are receiving this mail because: You are watching all bug changes.
