I Made MiniMax H3 Follow a Blender Camera (3 Tests)

Описание: Can MiniMax H3 follow a real Blender camera movement?

I used GPT-6 Astra to build 3D camera animations in Blender, then fed those animations into MiniMax H3 through ComfyUI to see how much control I could get over AI-generated video.

Instead of asking AI to invent complex camera movements, I gave it a camera blueprint to follow.

I tested three approaches:

🚗 *TEST 1 — BUILD THE CAMERA*
GPT-6 Astra creates an animated Blender previs for a Ferrari F40 shot, including camera orbits, speed ramps, a wheel dive, an interior pass, and a hero angle. MiniMax H3 uses the Blender render as its motion reference.

🧴 *TEST 2 — MORE REFERENCES = WORSE*
I tried controlling a perfume commercial using four separate image references. The result got worse. I restructured the inputs into two complete scenes and simplified the camera movement.

🐰 *TEST 3 — NO BLENDER, NO ASTRA*
What if the camera movement already exists? I used a movie scene as the motion reference, with new character and environment images to change its appearance.

*THE RULE:*
If the movement already exists, reference it.
If it doesn't, build it.

The results aren't frame-for-frame identical, but the experiment shows how 3D previs and existing motion references can help direct AI video.
