Executive Summary
Gen-3 Alpha continues to operate as the studio's most reliable cinema-grade text-to-video system. Rendering passes remain clean at 24 and 30 fps, temporal jitter is finally controlled, and the diffusion stack honors both dialogue and action prompts without hallucinating set pieces.
Motion Stress Tests
Repeated orbits, dolly-ins, and parallax flyovers across ten 12-second sequences kept horizon drift to < 1°. Even in high-contrast environments the model retained subject scale, which means less roto cleanup in post.
Shot-by-Shot Diagnostics
- Interior Steadicam – zero mid-shot flare, metadata indicates consistent exposure ramping.
- Exterior Drone – tree lines preserved, micro-judder only in frame 281; fix with optical flow recode.
- Close-Up Dialogue – lip sync holds, eyelid ticks resolved compared to Gen-2.
Prompt Engineering Notes
- Keep camera calls at the end of the prompt:
medium close-up of... | Camera: handheld | Lens: 35mm anamorphic. - Embedding color palettes (
palette: kodachrome-1974) yields more stable key lighting than specifying LUTs. - Negative prompt
compression artifactscontinues to shave 4% banding from sky gradients.
