Thanks, previously I'd been trying a huge combination of filters to try and get the results I wanted, till I found a single VirtualDub noise filter that does most of the work. I'm using a Canopus ADVC-100 capturing from a Pioneer CLD-D515, I'd like a better LD player but couldn't justify spending a lot more on something I won't use that much.
I undid the 3:2 pulldown before making the jaggy example stills (they're only cropped) so it's not the interlacing that's at fault but whoever mastered the LDs, the 2.35:1 letterbox Blade Runner LD doesn't suffer from the same jagged/broken horizontal lines as the definitive LDs.
Does anyone have some unedited captures of the PAL SW LDs? specifically where there are some almost-horizontal lines
"Each one has the deathstar THX intro"
"Which intro is this???"
It's when the disc starts, appears to be CGI generated, a sequence where the x-wings fly down to the death star to blow it up by firing into the exhaust port, but when they pull away you see it's the THX logo not the deathstar they blow up.
