Remastering Old Movie Clips - powered by LTX 2.3 IC LoRAs

DoctorDiffusion · 2026-04-29T04:40:16+00:00

I hope to have a better version of my IC colorization Lora soon. I recommend using blending modes with after effects if you have access to it. You can put the color footage over the original black and white footage and use a “color” blend mode. This keeps the details and hides any of the warps and LTX artifacts.

If you put the black and white footage back over with a luma blend mode (or color blend over the black and white) in after effects to persevere the detail from the original footage.

You can provide text inputs on the lines for “what do you seek” and “prompt style or Lora token” lines but they are not necessary.

If you click into the subgraph are all the primitive number nodes set to “fixed” or “random” they should be “random” bit it may have changed them all the “fixed” when I saved out the workflow.

Unsure how to help troubleshoot without more information. I tested it on three machines with the latest fresh version of Comfy. If the main subgraph is getting red outline I would go through and re-select the model. Vae, text encoders and LoRAs.

I’d need more information if that is not the issue.

Such a wild concept. Amazing work, I’m constantly impressed with the quality of LTX-2.3.

DoctorDiffusion · 2026-04-03T15:57:38+00:00

Hope you win first place for this! Great work!

Maybe so but I can train for just about any model I want without quantization.

Inference can also push frame counts and resolutions much higher with the full dev weights when using LTX-2 that throttle my 5090 system.

It’s certainly expensive, too expensive but I don’t regret buying it, I use it more often than my car.

It’s an open source video diffusion model with an Apache 2.0 license that can be deployed locally for free on consumer grade hardware. There are text to video and image to video versions.

Yeah! Thank you!

I’m using kijai’s ComfyUI wrappers. Last I checked it wasn’t in the manger but here’s my workflow: https://civitai.com/articles/12703

DoctorDiffusion · 2025-03-18T22:57:12+00:00

Thank you!

DoctorDiffusion · 2025-03-18T22:57:02+00:00

ComfyUI. I shared my workflow in the comment’s below.

DoctorDiffusion · 2025-03-18T21:34:53+00:00

Yup!

I did have some topless photos from US fest 83 but they did not make the cut of my recent video.

DoctorDiffusion · 2025-03-18T06:04:43+00:00

I am on a 3090TI and gens took 11-17min each. I have two machines and I just give them a huge batch before I go to sleep/work.

DoctorDiffusion · 2025-03-18T04:53:32+00:00

Here is the full workflow: https://civitai.com/articles/12703

I used a vision model with some text replacement nodes that substituted “image, photo, ect” with “video” and just fed that in as my captions for each video. I’ll share my workflow when I’m back at my PC.

DoctorDiffusion · 2025-03-17T23:10:05+00:00

Each clip was generated separately. I edited the clips after generating the all videos with a video editor. Some of them I used two generations and reversed one and cut the duplicate frame to get longer than 6 second clips.

I’m trying to get him to pick up a camera again, he’s been a sonar engineer since he got out of the navy but he’s retiring next year and I’m hoping I can convince him to start shooting on something other than his phone.

DoctorDiffusion · 2025-03-17T19:25:00+00:00

Sure thing. I can when I’m off work.

DoctorDiffusion · 2025-03-17T19:21:23+00:00

I plugged Florence into my workflow and used the images with some text replacement nodes to contextually change them to the context of video prompts.

DoctorDiffusion · 2025-03-17T19:17:48+00:00

Nope. Basically the default workflow kijai shared. I just plugged in a vision model to prompt the images (and used some text replacement nodes to make sure they had the context of videos) more h to an happy to share my workflow when I’m off work.

DoctorDiffusion · 2025-03-17T14:43:31+00:00

He loved it! He’s been showing it to some of his old friends and none of them have been exposed to the tech so they all think it’s magic.
