Preview the visual path before video generation
Frame Preflight creates approval stills for the beginning, middle, and end of a shot when the selected model route supports that planning flow. It helps catch wrong composition, reference drift, action jumps, and impossible timing before a proxy or master run.
One shot, sampled through time
Approval frames should behave like moments from the same continuous take. A first frame is treated as the starting visual truth, while character, location, product, and style references stay in their own lanes instead of becoming accidental end frames.
Use feedback before spending more
If the frames do not match the script, the feedback should describe what is good and what is wrong, then help prepare the next take. The aim is to fix the route or prompt before more expensive video work begins.
