odd vertical like line noise in video do not think it is from interlacing

[mazinz]

I am working on restoring an old project someone made and the main issue was that from whatever they used to encode, produces these transparent but visible vertical like lines in the picture. It was from a custom made dvd. Here is a direct 9 second rip from that disc where you can see what I am referring to

The dvd is a 16x9 ntsc format, but according to gspot it has a 3:2 pulldown flag applied and is interlaced

Does anyone know if it is possible to even fix this artifact? I cannot go back to source material so I have to work with this final product

no interlacing it's progressive. and interlacing artifacts wouldn't be vertical. just a piss poor encoding job all round.

Aside from the poor encoding, there was some kind of noise problem before the video was encoded. It's going to be difficult to fix. You really need to get the video before the MPEG encoding. Here's a quick treatment with Mpeg2Source, deblocking, deringing, and McTemporalDenoise in AviSynth.

Thank you both for the replies. This was a fan project someone made back in 2008 and I could not approve it for where they wanted it to go due to these tech issues. However the person ended up never fixed anything and disappeared. This project crossed my mind the other day and I wanted to see if it was even salvageable. I know the original creator put quite a bit of work into it but the encoding was like sh*t

The filter chain you mentioned Jagabo worked well, curiously (and after) I also put the mpeg source into an older version of tmpg (tmpg 2.56) and pretty much blasted the noise filters on it and then lowered the contrast by -3 so it restored the lights in the building. It came close to the avi synth sample in the end (but of course synth having the edge over it)

This film project is a little over 2 hours, so it begs the question do I want to spend quite a number of hours or days letting the pc re-encode this thing.

I do appreciate the help because those vertical lines were driving me nuts
