hello,
i have a BD (concert) which I copied to my HD with makeMKV.
Now I'd like to deinterlace it using for example avisynth.
The BD box cover says the video is 23.98 fps and the frame pattern is 4+2 (4 progressive followed by 2 interlaced).
What kind of command should I use to get it deinterlaced?
Thanks (if needed I will attach small sample)
edit:
ops, I think there is nothing to deinterlace and what I need is some kind of pull-down removal
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Yes, a sample. 23.976fps is, almost by definition, progressive.
10 seconds of steady movement will be plenty. Sounds like a crap PAL to NTSC conversion. -
No. It's PAL to NTSC (and actually a pretty decent conversion). Try this:
TFM
TDecimate(Mode=0,Cycle=6,CycleR=1)
After TFM alone there is one dupe frame in every 6, not in every 5 as would be true with standard telecine. Making it 23.976fps results in one missing frame every second. -
Thanks manono.
I looked at it quickly - I thought it had a slight jerk, hence the qualification in my post.
Hopefully, the OP will come back for the fresh info.
I noticed that gives a frame rate of 24.975. Where's the original 25 fps? -
Don't know. Apparently it's from a 29.97fps Blu-Ray. It could easily have been slowed to 24.975fps before 'telecining' it for NTSC. Or maybe it really is supposed to be 25fps, but I'm not going to count thousands of frames looking for that one missing frame in every thousand. If you (or adom) think it should be 25fps then you might try:
TFM()
TDecimate(Mode=2,MaxNDL=4,M2PA=True,Rate=25)
but that opens the possibility of decimation errors where there's not much that can go wrong trying to pull out a dupe frame every six frames.

I think the first solution is fine, I really don't care if it's 24.975 or 25.
Just finished converting and muxing with audio - all plays fine, no av sync issues.
Thanks -
