Super thick interlacing lines
Anyone ever seen this before? I’ve got this old footage, it appears to conform to the WWSSS interlacing, but the lines are SUPER thick, not like the usual very fine interlacing lines. I’m unable to do anything to get rid of this. Anyone ever seen anything like this?

is the footage interlaced? Meaning, is it reporting that it’s 1080i? Or is it progressive with that interlacing built in? I’ve come across that TOO DAMN MUCH in my work on archival docs.
OR…are you trying to use interlaced footage in a progressive sequence? IN which case, you need to de-interlace it.

This footage is progressive but was likely (incorrectly) captured from an interlaced source.
When I attempt to deinterlace this, the scanlines are tiny compared to these huge scanlines.Just noticed my original post didn’t correctly link the image, trying again here:

If it’s progressive, that means that it was incorrectly captured. If you captured, then recapture as interlaced. If you licensed it, or obtained it via third party, ask them to re-capture or re-encode it properly.

Unfortunately this is the only copy available. Still wondering how the interlacing lines are so huge.

If interlaced footage is ingested into a progressive Raster without de interlacing and scaled the field differences clump up giving fat lines. At that stage it’s impossible to de interlace.

The organization I currently work for has a large amount of archival footage in its system that was captured improperly and has this issue. Hopefully, they still have the tapes in a vault somewhere, as I’ve been informed that the cost of recapture is too great to undertake at this time.
Usually you can minimize the problem in Premiere by right clicking on the clip in the sequence and selecting Field Options/Flicker Removal. This results in a slightly softer image, but a lot more usable.
