Hi! I have a 240FPS video made by GoPro and I'm looking for a way to gradually change a video framerate. If I want to simply slow down a video I can use:
ffmpeg -i raw.mp4 -filter_complex "[v:0]setpts=8*PTS" -r 30 out.mp4 and it works fine. But when I'm trying to use a "variable" framerate like this: ffmpeg -i raw.mp4 -filter_complex "[v:0]setpts='lerp(2,8,T/5)*PTS'" -r 30 out.mp4 (5 is a video duration in seconds) the resulting video stutters a lot. Is there are a correct way to smoothly change the framerate using some curve/function? Thanks. _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
