I don't see my recent mails to the list posted here so I will try from my browser (I am new to this mail list format).I have been trying to convert a telecined clip (29.97 fps) to a progressive one (23.976 fps).The clip I am using for test purpose is here: https://dl.dropboxusercontent.com/u/71351606/TermSample2.mp4 <https://dl.dropboxusercontent.com/u/71351606/TermSample2.mp4> The sample contains a x.264 video stream and an AAC 2-channel audio stream. I first tried to use -vf pullup, fps=24000/1001: The log is here <https://dl.dropboxusercontent.com/u/71351606/pullup_fps.log> The result was a 23.976 fps clip, showing up as 'progressive' with MediaInfo, but with 2 progressive frames, followed by 2 frames each blending 2 fields (combing). I also tried -vf pullup -r 24000/1001 as some users mentioned that this worked for them:Here is the log: here <https://dl.dropboxusercontent.com/u/71351606/pullup_rate.log> The result was the same: 2 progressive frames followed by 2 blended ones. I then tried -vf fieldmatch,decimate: The log is here <https://dl.dropboxusercontent.com/u/71351606/fieldmatch_decimate.log> Different result here: most of the time, we have 3 progressive + 1 blended frame, but on occasion 2 progressive + 2 blended.I do hope someone knows how to make IVCT work under ffmpeg.Thanks.
I think your problem is that your media is not actually 29.97 fps. ffprobe reports 28.97 fps, multiplying that by 4/5 gives 23.76 Try just -vf pullup,fps=23.176 no fps argument. Worked here. -Nick
