LTX-2.3-22b-IC-LoRA-Colorization
Would you be able to work your magic to create a workflow for the new Lightricks IC LORA Colorization please?
Ideally with the ability to do long videos, using a gemma to describe the scene for the lora, and a toggle for a reference image?
It would be awesome if the new upscale lora could also be toggled too?
I've seen other workflows but they generally only work for shorter videos but i'm working on some longer restoration projects.
https://huggingface.co/Lightricks/LTX-2.3-22b-IC-LoRA-Colorization
This is a Colorization IC-LoRA trained on top of LTX-2.3-22B, which restores natural color to grayscale, monochrome, or desaturated video while keeping subject identity, framing, and geometry untouched β only the color information changes.
Long videos are always a challenge. But by luck someone made a looping sampler, that might make this all much easier https://github.com/ckinpdx/ComfyUI-LTXAVTools
Will give it a try soon ; -)
(alternatively a manual loop, been meaning to try that with the newer ID-Lora etc, so might as well make it a bit generic so it also works with other loras)
nice! I need to change an outfit on someone in a long video (5 minutes), what workflow would you recommend?
this one? LTX-2.3_-_V2V_Video-Edit_remove_add_replace_restyle_EditAnything-Lora.json
Do you think that looping sampler could make long videos possible for it?
Yes the add remove replace workflow should be able to change the dress.
But 5 minutes video will probably crash comfy.
The looping sampler addresses that, so in theory it should make it possible. Will try it out asap
Thank you!
