[FFmpeg-user] Inverse Telecine with fieldmatch filter

[L. Lee]

I stopped getting responses to the following thread, but I would like to
try again.

http://ffmpeg.org/pipermail/ffmpeg-user/2013-April/014661.html

I'm using the latest git version and the problems I was having with funny
pixelation seem to have disappeared since I last experimented, but now I
need help with cropping.


Please consider this short .mpg clip:
https://dl.dropboxusercontent.com/u/42718751/Blockyclip_mpg.zip

Why does neither of the following commands result in removing black bars
for current playback?

ffplay -i Blockyclip_mpg.mpg -vf "cropdetect=24:16:0"

ffplay -i Blockyclip_mpg.mpg -vf "cropdetect=24:16:1000"
