(But this is unrelated to pulllup / pulldown.) > 6) -vf pullup,dejudder,fps=fps=24000/1001:round=zero There is now (it was there before, but nobody realized afaict): -vf dejudder,fps=30000/1001,fieldmatch,decimate > You have to use your eyes. There is of course the idet filter that allows to detect the non-mixed cases. Carl Eugen PS: A bug in decimate affecting the first five frames of the output stream was reported and should be fixed soon. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
