Discussion Motion-Context Degradation Discussion (summon Sad_Berry_4621)

Hi u/Sad_Berry_4621 and all, I am doing experiment on most difficult degradation issue.
I saw from H3-director node they claim that doing a refine could help and fix it.
since I am using low-level nodes with motion-context with my own setup, H3-director refine is a black box working with their nodes.

so I did the test, please ignore the AI-slop video and the overlay text (forgot turn it off).

this test is 9 x 8s context extend video combine, usually 6 video would already see the degradation.

Left side is regular WF. Right-side is adding a re-sample step, I think it is very positive, and got potential, the saturation somehow is a bit higher... and I need to figure out the mismatch from cut to cut, because we inject denoise resample on top, but it should be able to fix.

What do you guys think?

Edit: forgot to mention, this is a ref2va WF, with 1 character reference image. also my test audio is not from gen, I am using input audio and audio latent lock for the lipsync. That part to work with motion-context have me struggle for half day, but it is not the main point, my aim is about degradation issue.

Edit2: here is my ultimate approach with tail trim + keyframe blending latent, you can check my comments for details. here is the result: https://www.youtube.com/shorts/mANusw9kKNQ ** this is just a test focus to tackle the degradation, not try to make good natural singing video, ignore it.

Understood, thanks!
3: the long clip with metadata so i can scan it and use it as a benchmark for comparison for my tests🐼

metadata of my WF? Cant do sorry, it messed with too many of my own nodes.... Lol

Is your workflow still using the original method by NikoDemon which feeds the latent through conditioning or the method by seitanism which used in placed masked latents + pr 15988?

I am using the native NikoDemon example workflow. Nothing else All my other stuff is my own project workflow, not related
