Does what name suggests.
Allows setting up any combination of frames - be it start and end, single frame in the middle, start->33%->66%->end.
Native and KJ's Wrapper solutions, but Native doesn't work for some reason.
Wflow consists of three parts:
Keyframes setup
Native VACE
Wan Wrapper VACE
You can set up frames any way you want, but keep masks consistent with keyframes - their locations in batch should match. Basically, you should 'protect' keyframes from VACE with empty masks and allowing them to be used for reference. As example .zip contains image grid that is split in four images that are used as keyframes; gaps between them filled with empty frames. This is the only relevant part of wflow, the rest can be found in examples.
Native VACE and Wan Wrapper VACE functionally same, just different implementations - use one of those. Provide prompt and hit run. CausVid and AccVideo loras are used to speed up generation at some cost of quality, both provided in KJ's hugging repo.
Native currently isn't working (or rather start-to-end frames are working, not the rest).
WanWrapper has separate VACE module (grab it from KJ's repo), meaning it can be used with various finetunes such as Phantom and MoviiGen, which makes it preferable and superior option.
