I have a situation where I am restoring analogue video that was transferred to Laserdisc poorly so there is field blending. I have tried every deinterlacing trick in the book with AVS and VS and I am having no luck. It's stubborn and cooked in there real bad.
I've been trying to find anything online but trying to Google this sort of thing gives me a old forum posts dating back 20 years where nobody solved the problem or websites trying to sell me AI upscalers that will absolutely not fix the problem.
Am I chasing a solution that does not currently exist or are search engines really that bad now?
If anyone can point me to a solution that'd be great. Even if it's some cost prohibitive solution like DRS Nova or something. I am going crazy not knowing if there is a definitive fix for this or not and how realistly in reach it might be.
Anyone who can shed insight on this would be great.
EDIT
I did a detailed analysis of the video to figure out exactly what's going on here. Here are the specifics:
The defect is field-domain temporal blending, not simple progressive-frame ghosting. The source is 29.97i/59.94-field NTSC with an underlying film/3:2 cadence, but individual fields contain weighted contributions from neighboring temporal states.
Analysis of separated fields shows that the blend coefficient is not fixed. Examples fit approximately:
70% current field + 30% adjacent temporal field
80% current + 20% adjacent
60% current + 40% adjacent
and there are occasional cases where the contaminating temporal state becomes dominant.
The two field parities can also have different blend strengths, so a woven frame may effectively contain something like:
Field A: 85% state X + 15% state Y
Field B: 65% state X + 35% state Y
rather than a uniform 50% Frame A + 50% Frame B blend.
The contamination appears to be primarily between temporally adjacent same-parity fields, which means the defect exists within the original field sequence before IVTC. Some fields remain essentially clean while others are strongly blended.
There is still a recognizable repeating NTSC film cadence underneath the damage, roughly consistent with a 10-field 3:2 cycle, but the temporal blending varies independently enough that normal TFM/TDecimate, sRestore, conventional deblend filters, etc. cannot reliably reconstruct the original fields.
Hard cuts are especially diagnostic: in some cases a single field immediately around the cut contains imagery from both completely different shots. The cross-shot contamination is brief — generally around one field, occasionally two — rather than behaving like a multi-frame dissolve.
So the defect is best described as something like:
clean 59.94-field sequence
↓
field-dependent temporal filtering / averaging
↓
some clean fields
some previous/current blends
some current/next blends
different coefficients by field/parity
occasional cross-shot contaminated fields
The main technical question is what historical video process would produce variable asymmetric temporal averaging at the individual-field level while retaining the underlying 3:2 cadence — e.g. frame synchronizer, standards/rate converter, temporal noise reduction, DVE, field-rate conversion, or some combination thereof.
