Recreating quiet TNG acting with MiniMax H3: why I had to regenerate a whole film at 1MP

A Reddit user describes making a 4-minute quiet Star Trek: TNG-style short (Picard reflecting on The Inner Light) using MiniMax H3 in ComfyUI, focusing on subtle facial acting rather than action. Workflow: generate starting frames, render each shot individually with heavy discards, edit in Premiere Pro.
Key lessons:
- Resolution consistency matters: mixing 1MP and 2MP shots caused frame dimensions and black-border widths to drift subtly between cuts even at the same 4:3 ratio; after OOM issues on a 4090, the author regenerated the entire film at uniform 1MP.
- Aspect ratio ≠ frame geometry: ratio is the image shape, resolution is the pixel geometry — both should be fixed from the start.
- Quiet acting is harder: restrained performances meant tiny errors (a smile too wide, a pause half a second too long) made shots unusable; treat H3 like directing an actor through takes.
- Reaction shots do heavy lifting: generating silent coverage and carrying dialogue across cuts both feels more traditionally edited and hides inconsistencies in faces, lighting, and posture.
