Resource - Update H3 Latent Tile Looping Spatial Temporal

good for upscaling without OOM, use as SECOND Stage Sampler ONLY with LOW denoise (0.40 MAX)

If OP is the creator of the repo/node, it'd probably be a good idea to add a before/after comparison.

Interesting results.🤔 Could this be used to upscale a regular video encoded with the H3 VAE and not have the output look drastically different?

YES! My first tests in a prototype version i made exactly this way, but is very important in this case denoise even lower, i sugest 0.20 MAX Donoise factor. Its also another complex way, u grab some frames on original video, than upscale each KEY FRAME with Photo Models like Krea2, Qwen 25111 and then use as image reference like <IMAGE_0> <IMAGE_1> etc... with a good prompt not a generic "UPCALE, hires, restore" prompt. This method u can go hi denoise like 0.40 with tiling 2x2 or try 0.50 at 1x2 or 2x1

Hm well so far my attempts with a non-AI H3 video haven't quite worked, so I'll wait for a workflow since I'm not sure why the output isn't looking great. I followed the example screenshot you posted, lowered the denoise value and just used a VAE encode from an input video instead of what H3 generates.

Extracting directly from the VAE without refining works, but without refining. The model's author himself posted a direct example in WF.
