Odd chroma ghosting with SDI capture setup? Possible causes and fix?

[aramkolt]

Hello all, I've noticed that on some of my U-Matic captures seem to have what I'd describe as "chroma ghosting" where either the chroma lags behind the luma or there's some sort of frame blending occurring which can be seen at sharp scene transitions or during rapid movements. It's unclear to me if this is something inherent with edited U-Matic footage maybe? I only seem to see it on commercially produced tapes that were probably originally shot on film.

I've attached a very short clip where you can see the man's hand has multiple ghosts as it moves across her back. I am pretty confident that the tape itself was telecined as some frames do not have interlacing and it was pretty clearly originally shot on film.

Thing is, when I do IVTC, those ghosts are still there.

The sharp scene transition here might just be a "crossfade" so that might not really tell us much about the rest of the ghosting.

This happens to be from Roseanne Cash's Blue Moon and Heartache - There's a different capture of it here starting at 1:14 and the ghosting seems to be there as well, so I presume it somehow got into the master recording: https://www.youtube.com/watch?v=i07roS2Aio0&list=RDi07roS2Aio0&t=74s

Here's the IVTC'd capture I got, but you can still see it is pretty distracting and can't be "unseen":

Is it something that can be improved?

That mov is encoded progressively not interlaced, you might want to share a sample that preserves the original fields/format.
Handling what you attached, you can try Cdeblend.
Attaches a sample where I used TIVTC+Cdeblend.

Since the video is 4:2:2 chroma subsampled it shouldn't matter that it's encoded progressive rather than interlaced (each line has it's own chroma). The chroma blurring must have happened before it was encoded.
