LTX-2.5 Enhancer Studio GUI v1.1.0

[skv89]

I released a new user-friendly version of the LTX-2.5 Enhancer Studio GUI for CQDSN's new version of his LORA video enhancer. This will make it easy for those that are not familiar with ComfyUI or do not want to tweak the workflow in ComfyUI.

The quality is definitely better than the 1st one. Good job CQDSN!

I found that upscaling is the way to go. So if you have a 1080p video, downscale first to 540p and then upscale it back to 1080p (1088 to be precise). The downscaling option is part of this GUI.

From my very brief testing, I find the quality as good or better than SEEDVR2 even though results are not as sharp as SEEDVR2. The images are more stable and smooth similar to SLM, the skin is smoother with less skin defects. It handles fast motion scenes better with less ghosting so I think this LTX 2.5 CQ has potential to be the preferred enhancer over SEEDVR2 for certain videos. Starlight Precise (SLP) though still seems overall better than LTX 2.5 CQ in most cases, but LTX 2.5 CQ preserves the original look better so I see it as a potential alternative to choose from. Also SLP descended from SEEDVR2 so it shares the same issues as SEEDVR2.

However LTX 2.5 CQ's speed is really slow. It processes at 0.68fps on my RTX 6000 Pro for 1080p outputs. SEEDVR2 can process at 1.5fps and Starlight Precise process at 1.03fps with Topaz default and 2.0fps using my SLP Tuning app. I wish LTX 2.5 CQ was faster than SLP, in which case it is a real viable alternative. I haven't had time to really try different settings to see if I can speed it up but I hope CQDSN can see if there's anything that can be done to increase speed. But regardless, I'm happy there are progress made outside of the SEEDVR2 based enhancers.

For anyone interested, I spent the last two weeks trying to squeeze performance out of this and I was able to get about 2x of the stock workflow. Basically increasing from 1.457 fps to 4.441 fps outputting to 1280x720p. It is about the same speed or just a bit slower than an optimally tuned SEEDVR2. There are pros and cons between both enhancer but at least there is another easily accessible alternative to SEEDVR2 and SLP

I'm very interested in SeedVR and SLP alternatives, thank you!
