Hi,
so 18.3 % of the frames were dropped and duplicated at same time.
Does that mean, that 8063 frames of the input were dropped and then same
(or other) 8064 frames were duplicated to the output?
Probably variable frame rate input.
When I use "-fps-mode passthroug", then I get messages of frames with the
same timestamp, so ffmpeg seems to drop them in normal mode and then fills
in duplicates.
Am I right?
So maybe it would be better to correct the timestamps than dropping the
frames?
Could use vfrdet video filter on original input to find minimum, average
and maximum delay between frames.
So I get this:

What do the numbers mean, are this nano seconds ? (the ffmpeg docs don't
outline this)
