Slowly working on Star Trek #DS9 and #Voyager with AI upscaling - I'm a fully professional amateur 😀
Stay a while and listen!

Playing around with my friends Dot crawl Mask again.
The rough logic of the mask is it rotates the image and uses three (technically six) comb detectors to roughly find dot crawl, and it uses an alternative 1x AI processed clip to gen a chroma edge mask to limit the detection to chroma edges.

Just some upscaled #DS9 screenshots from the @ds9redefined.bsky.social Project.
I'm just getting back into the swing of things after summer and holidays. Lots to do in the limited spare time i get!
Hope everyone is well 🖖

The Colors, Duke, the Colors!
There’s more aspects than you’d think when it comes to how an image looks. We still plug away with research and trial and error, and I’ve decided 3 things: It is probably impossib…

It is fun going over old forum posts - here is April 2006 (a new rig arrives) Blast from the past..... Opty 170 CPU :)
PS - that motherboard from DFI was defective, the one before that was legendary!

Just to follow up - looks to be a Rec 709 conversion from NTSC (470m) but they did NOT do a gamma or whitepoint adjustment. If you do a correction with that understanding you get mighty close to Laserdisc colours, at least with a little sat boost.
These shots show its now much closer! 👍

Interesting looking at #StarTrekVoyager Season 4 DVDs
Its a season with a really bad magenta swing. Something deffo went pear shaped in the DVD authoring of that season as the Laserdiscs are not affected.
Anyone know anyone in the know from that time? Could be a setting was out, mishandling BT 601

Got to love prep work 😀
lossless mp4s from Laserdisc
So begins a lot of pre-prep. Getting each episode into a "ready to go" master state is the next step, so if I want to (in the future) air drop the latest tech on them
Its a lot of iterative work at the moment, you need it all rdy 2 go @ Ep1

Hot off the press sneak peak look at the work JonnyPoe (a fwend) has been cooking up.
We figured the colourspace and gamma conversion to 470m previously but something was still bugging us on wayward colours. Thats fixed now - he'll be documenting it soon - works on nearly all DVDs/LDs all look 👍

Found some childhood drawings by me looking through some old folders/books a while back - thought I would share here - quite pleased with my meshing of Chaos together!! #Warhammer40K #W40K
I did love my combat cards! Still got them all as well, plus a good few White Dwarf magazines.

It can be better to look at edge masking so dreamed up badness can get masked out or handled better. And with multiple AI layers the hope is to reduce issues as much as possible, we cannot go back to a super HQ source that the studios could, its their trump card.

Take this still from #StarTrekVoyager for instance - Paris can come out ok but the Captain behind is mid/far distance in the frame and with not much to work pixel wise some AI models can get a bit...... wild if you let them (see here also) (2/3)

Why is this important (Depth mapping and masking) well remember this is old SD land video in modern terms its tiny 640x480 essentially, with less than 4% the pixel count of 4K the AI upscaler does not have much to work with, and they can be a bit dumb and treat all parts of the image the same (1/3)

Ain't Depth mapping fun!
Some testing with Video Depth Anything here on "Q-less" S1
#DS9 - the aim is to layer various masks and AI upscales to almost emulate photoshops layers but with video 😄

It looks like the following image here
