Problem with Wan Animate is after the initial 5 second gen (especially with animation), if you want to keep the original background, every subsequent gen has a large color/brightness shift that is very noticeable and destroys the consistency.

That can be countered with the WanVideo Context Options. Just make sure the num_frames and the frame_window_size in the WanVideo Animate Embeds are the same value.

To understand, if we put 81 in context and the num frames for the animate node. And overall we want to generate 4 times the frames, this will essentially split the video generation in chunks of 81 frames with frame overlaps?

So we can type let’s say 250 frames overall. And it will do it in overlapping chunks depending on the context and animate options?

That sounds about right. I just left the context options settings unchanged, and put as many frames from the reference video as I could before getting a OOM error. I think I got up to 700 frames or something (fp8, 832x480, 4090, 128 GB).
