Fix blurry, smudgy, muddy video gens with this tiled V2V upsampler. Previously unusable garbage-bin gens can be polished into high quality production shots in minutes. LTX 2.3 notoriously produces smudgy motion, and high FPS / quality keyframes only mitigate the issue so much. Watch the video below for examples and a full walkthrough!

I've been meaning to mess with something like this. One of my concerns was length and seams across clips and lip sync. Wan has great coherence within it's own work space, it seems like you'd get something like moles and other skin details suddenly shifting as you transition across the 5 second clips.
@foxydits Very cool, thanks for sharing and I love your stuff. I've been optimizing with this wf a bit and it seems to not need LightX2V LoRA if increasing to 8 steps, and this also seems (at least so far) to reduce unwanted artifacts like complexion issues. Have you tried without it?
Also, does your experience suggest it's better to interpolate before or after this? Same question for like a SeedVR2 type upscale, better before or after the V2V low denoise pass? Thanks again.
I did try without turbo LoRA a long time ago, but got bad results. Never tried it again.
This is definitely better done before any interpolation/upscaling.
Interpolation because blend frames are usually blurrier and harder to reconstruct, and upscaling because it's just slower if you do this afterwards. The only time you'd do this after upscaling is if your upscaler creates low quality artifacts that this wf can fix... which, thinking about it now, is pretty common.
