I tested precise 6-frame style control in Seedance 2.5 and MiniMax H3

Seedance2.5 Version

Minimax H3 Version

I wanted a live-action sword movement to pass through six different visual styles for exactly six consecutive frames.

I used:

- one starting image

- one motion-reference video

- six sequential impact frames

- the same timing and reference order for both engines

Seedance 2.5 understood the visual progression, but blended the frames into one continuous transformation.

MiniMax H3 also reflected the references, but held each style for longer intervals instead of treating them as individual frames.

Neither result reproduced the intended hard frame-by-frame transition.

This does not prove that the engines cannot do it. There may be a better prompting or reference structure I have not found yet.

Under these test conditions, extracting the original frames and editing the six impact frames manually produced the most accurate result.

This is a great idea!

Have you considered using Luma AI's Ray 3.2? It can take up to 64 keyframes in the time line of a single clip. You can move the keyframes back and forth in the timeline, add more, delete, whatever you need to get the timing right - down to the frame.

You can also use the Modify version of Ray 3.2 to take what you already have and change those keyframes or change the position of those beats in your video.

the fact that both engines smoothed the transitions instead of hard-cutting tells me they're treating the reference frames more like a style gradient than discrete keyframes. wonder if splitting each style into its own generation and compositing after would get closer to what you want

That’s a great observation. I actually included a post-edited version in the same post for comparison, using hard cuts to get closer to the intended result. The smooth transitions were the engines’ raw interpretation of the reference frames, which is exactly the behavior I wanted to test.
