[FFmpeg-user] telecine pattern 5555 - Judder-free, 60 FPS telecine (?)

[Mark Filipak]

Hi Carl Eugen,

Given a 24/1.001 FPS source, how can I get -vf "telecine=pattern=5555,bwdif=mode=send_frame" to 
produce 60/1.001 FPS instead of 75/1.001 FPS? That is the issue.

Well, that's the hazard of having to find examples from the Internet when ffmpeg docs don't have 
them. I don't like spending all night hunting for solutions, but what choice do I have?

...Because of PGCs (program chains), right? I know how to handle them.

Above, you wrote that the deinterlace option is deprecated. I won't be using it. bwdif seems to work.

It appears you haven't been reading this thread. I'm telecining to 60 FPS using 5-5-5-5 pulldown in 
order to defeat judder. It's working. Simply converting 24 FPS to 60 FPS doesn't defeat judder.

The source is p24.

It's my understanding that fieldmatch is for detelecining prior to decimation. Kindly correct me if 
that's wrong. I am not detelecining.

I'll keep that in mind, but I think the problem is that telecine=pattern=5555 is producing 75/1.001 
FPS instead of 60/1.001 FPS. Why it is doing that is my issue.

The source is not telecined. The source is p24. I'm doing the telecining.
