Films that sit still: we checked the check first
Nothing moving was our biggest film failure, 43 frames. We sampled every scene five times before touching a film. All 43 move, then rest. The check was wrong, not the films.

Two scenes the old check called still. Both move. Then they hold a beat so you can read them.
The problem
After the judge fix, the top failure was a scene where nothing moves. 43 frames out of 277. A film that sits still is a slide, so we were ready to rewrite the film prompt.
First we looked at how the check decides. It compared two frames, 0.6 seconds apart, in the middle of a scene. A scene that moves, then rests, looks identical at those two moments.
What we did
We sampled every scene of the same 50 films at 20, 35, 50, 65 and 80% of its length, plus the old two moments. The new rule: a scene is still only when nothing changes across all of them.
Then we looked at all 43. Every one is a hold beat. Not one is a scene that never moves. So there is no never-moved frame to show you. We looked.
We scored the films twice with the new rule. 277 of 277 verdicts agree.
What changed
Only the check. No film prompt change, no kit change, the app plugin untouched. There were no real still scenes left to fix.
The numbers
- Same 50 films, same vision verdicts, old rule then new.
- Still frames: 43, then 0.
- Frames passing: 52.3%, then 61.4%.
- Films with 80% or more passing: 22%, then 36%.
- Plain 36 and off-subject 36 did not change. Cramped stayed at 19.
Next are plain and off-subject drawings, 36 frames each.
