I work on old cool shows/cartoons in my spare time aiming to bring them into HD land. I also sometimes stream games n'stuff over on twitch!

First test, trying to follow USC's ETC teams EXR pipeline. "When applying color transforms, source 8-bit footage fell apart immediately with crushed highlights and limited push/pull capability. The processed 16-bit version maintained integrity under aggressive grading"
Very basic, No Bells #DS9

Some shots from my S1 "The Nagus" LaserDisc-sourced, IVTC’d film master (Rec.709 / BT.1886), lossless #DS9
So that means NO AI Upscaling here or anything other than proper colour correction described in my previous posts at this stage.
Size wise this its cropped 740x480 and still 3:2 DAR @ 23.976

Fun sorting out folders and actually putting scripts and code etc in the right places. It was previously anywhere I liked, will probably re-discover important stuff I've already solved no doubt!
See here, I found my very first Depth Mapping tests done on #DS9
Its from Season 2 - 'ShadowPlay' 😎

More #DS9 Redefined colour correction work ....
due to all the work put into figuring out why the show (and other 90s shows look pretty pants) Here is a good read over at the other place lol....

On my R&D testing to do list, looking at emulating the USC Video AI pipeline of going 8bit - 16bit HDR EXR files, I think I will have their tone mapping colour issue fixed. Then colour channel splitting work mentioned in a corridor crew video recently so R,G and B separately into the AI upscale!

More shots from the Davinci render of Seans work - its not had any of the colour correction work yet (this is #StarTrekVoyager Season 7) so there is that. Still early days on this render pipeline in fusion too. Its very much a starter for ten!

Looking over some excellent work done by my friend sean, aiming to get his fusion node tree to exe more efficiently in Davinci Resolve as it works but its slow atm. Its replicating his stellar AVISynth design on masking etc. I have a few ideas to test, here are some pre-grain injection shot of #VOY

So #DS9 via @ds9redefined.bsky.social is cooking through Season 2, take a look 👀😎✨🆒

Spending an age sorting the folder structure so it manageable all 14 seasons of DS9 & VOY
Ended up with this where each ep folder will house everything about it. Bare in mind this folder does not have my FFV1 archival LD copies yet or my working files, scripts etc
Thank god for big NASes 😉💾

"Sir we've had a 98% restoration of the Krenim empire" .... I feel his pain with a nearly solid AI model upscaling run ruined by the odd weird face and eyes @ mid range.

For those Nerds interested in the stacking of laserdiscs - since its analog data we can improve it with stacking copies (similar to astrophotography techniques)
Here you can see it rejected 31 frames, also see some frames it got rid of and how it monitors via MSE (Mean Square Error)

Probably posted this before but I do like that Laserdisc raw images smoke the god awful DVDs early seasons.

Team found something interesting. "Babel" and "Captive Pursuit" look like they had a different transfer process to DVD. They've got dot crawl like this ... (check images)
Our guess has been that for the DVD transfers they used a composite to component conversion that only had a 2D filter. [Cont]

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 🖖

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!

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
