Astra ran the Blender VFX from a loose brief

vogel's division of labor is the post. He gave general direction and storylines. GPT-6 Astra controlled Blender: renders, rotoscoping, tracking. The short was not "prompted at a video model." It was supervised inside a VFX scene, and he links a full breakdown.

That is a different skill from generating a clip. Roto and tracking are the unglamorous proof that something was actually composited. A breakdown you can follow is how the claim stays honest — which node, which pass, which part the human did not touch.

Loose direction is the impressive input. The output is a shot that had to survive contact with a tracker.
