Hi everyone,
I'm working to detelecine a video, attached here (12 MB, first 32 seconds
truncated):
https://www.mediafire.com/file/x4ly6moqb8ayfyy/detelecine_input.mkv/file
I wasn't sure what was the right command to get the result I wanted so I
looped over all possible combos like so:
for i in 0
The video is telecined, not interlaced.

I recently used the detelecine command in this thread:
https://ffmpeg.org/pipermail/ffmpeg-user/2025-May/059249.html
I got strange results with the `fieldmatch+decimate` combo, where decimate
wasn't removing the correct frame.
I also got strange results with the `pullup` filter.
This may just be
ayfyy/detelecine_input.mkv/file

And one quick note, my external video player (IINA and VLC) seems to not
like it if I don't include "-pix_fmt yuv420p" Otherwise I get strange
screen tearing issues.

I tried running your exact command and got the same result. Dropped frame
173 and a later duplicated frame.
I've attached 15 frames here of the results.

I've attached 5 frames each of the original input, usin
Thanks for your feedback, I tried your command but added a frame counter:
ffmpeg -i detelecine_input.mkv -vf
"fieldmatch=order=tff:combmatch=none,decimate,drawtext=fontfile=Arial.ttf:
text='%{frame_num}': start_number=0: x=(w-tw)/2: y=h-(2*lh):
fontcolor=black: fontsize=20: box=1: boxcolor=white:
lect='not(eq(n,1002)+eq(n,2003)+eq(n,3004)+eq(n,4005))
Since I noticed that the original file had a duplicated frame every 1000 or
so frames. The sample file does not reach 1000 frames and I didn't mention
it earlier for simplicity.

I put it there since it was in Huspnet's original command. I don't think it
matters, same problem occurs if I omit it or use -r 24000/1001 instead.

73.
In case you missed it, my test file was in the first message of the chain.
And using the detelecine filter got me the right result (with wrong params?)

Whoops, looks like I got cut off, the above command still has same issue of
duplicated frames 174+175 and skipped 173
