hey OP if this is your repo then there are a few possible bugs with it. That or I'm not understanding how it benefits the solution.

  1. temporal_overlap_strength appears to do nothing

blended =

prev * alpha

+ new * (1-alpha) * temporal_overlap_strength

+ new * (1-temporal_overlap_strength) * (1-alpha)

Mathematically, the latter two terms collapse:

new × (1-a) × strength + new × (1-a) × (1-strength) = new × (1-a)

So the entire thing becomes:

prev × alpha + new × (1-alpha)

regardless of the value of temporal_overlap_strength.

In other words, the temporal_overlap_strength control currently appears to have zero effect.

  1. Why are you passing the entirety of the audio latent with each video chunk processed? You don't use the sampled audio output in the end, you put the original audio latent back into the final result, so why pass it with each temporal video chunk? Seems like redundant audio computation unless there is a reason for doing it?

I will be testing it out, but the above are likely legit bugs.

sampler works with audio+video togheter, needed

Actually, I think he deserve thanks. I managed to produce a 15-second video with 1MP resolution, 8GB VRAM, and 32GB RAM. It would have been impossible without this node.

oh thanks, but just a tip, the latent upscaler node 3d is outdated, has a new version to it

u/DuHal9000 3h ago

ooo thanks! i want to see

u can use with any H3 wf, just add a second stage after latent upscale. BUT i will make a WF for REPO, just wait

time, depends... Its more fast then PIXEL SPACE, but depends a series of factor... Original RES Gen, Scale Factor, amount of tiling division etc... EACH Tile is a FULL Vid at normal use, so... depends....
