I have a vfr mp4 video from a private security cam with a very specific pts pattern. The duration of the frames is 80-80-40-80-80-40-80-80-40-... ms.
I would like to hand this video to others as a demonstration of vfr video, but have to blur it in order to preserve privacy. I tried something like ffmpeg -i in.mp4 -vf boxblur=10:1 -vsync 2 -copyts blur.mp4 which results in cfr video whith 15 fps. ffmpeg -i in.mp4 -vf boxblur=10:1 -r 25 -vsync 2 -copyts blur.mp4 or ffmpeg -i in.mp4 -vf boxblur=10:1 -r 25 -vsync 0 -copyts blur.mp4 generates vfr and kind of keeps the pts, but inserts additional frames. What goes wrong over here?
