Best deinterlace/detelecine method for this clip
#1
Hi all, I acquired this footage from the ELP DVD release "Beyond the Beginning." It is the source of the clip that King Crimson posted to their official YouTube channel, which has major problems. This version still has issues, and I was wondering if anyone could advise me in which way is the best to deinterlace/detelecine this footage in Hybrid.

It was originally shot on 8mm film, then converted to PAL video. I'm assuming it was originally 16p, then transferred to 25i, with further editing done. Any help is appreciated. Thank you.

Got no solution, but maybe a few ideas, that might be helpful.

The blends are a paint, since they do not seem to follow a pattern.
My first suggestion would be:
1. deinterlace with QTGMC(faster) in Bob mode
2. Denoise, remove scratches, etc.
3. try different target frame rates with sRestore (23.976, 18, 16) which were usually used
4. if you got luck and found a frame rate that removed most of the blends you could use some frame interpolation to get back to 23.976 fps

Another idea would be to use 'ReplaceSingle' to replace some of the blended frames through interpolated frames from the neighboring frames.

Depending on your system, you could some ml based filters for denoising and frame rate interpolation.
Sadly, CodeFormer will not work on such content.
Maybe I'll find some time to play a bit around with the clip next week. (won't have any access to a pc, with enough power for testing the next few days)

Thanks for your feedback, I will attempt your suggestions. Where exactly is "sRestore" located within the program's interface?

sRestore is located under 'Filtering->Vapoursynth->Frame->Reduction'.
For fun I used:
QTGMC
ddColor (needs torch-Addon)
BasicVSR++ (needs torch-Addon)
SpotLess
sRestore (18fps)
and let it run this night. Mainly to see how DDColor performs.

As a side note: adding ReduceFlicker (strength=3 + aggressive) helps with the luma flickering.
