Plan around the least documented step
Changing one shot is the step with the fewest help pages on the map. Luma explains regenerating one keyframe while approved frames stay; Runway explains editing existing footage with prompts; Storyboarder.ai explains its Iterate button. From 4 source pages, read 2026-09-25; no maker pays to be listed.
For a tool without such a page, assume a bad shot means generating the clip again, and budget time for it.
Shorter clips make that cheaper: less is lost when one has to be redone.
SceneMixer's guide on the step covers regenerating one segment while earlier versions are kept.
| Tool | Page | What it covers |
|---|---|---|
| Luma | Luma Scenes Complete Guide | Regenerating or replacing one keyframe while approved frames stay as they are |
| Runway | Creating with Edit Studio | Changing existing footage with prompts, from swapping a character to transforming a shot |
| Storyboarder.ai | Mastering the Iterate Feature in Storyboarder.ai | The Iterate button for refining or transforming one shot |
| SceneMixer | Fixing One Shot Without Redoing Everything | Editing one segment's storyboard and regenerating that segment alone |
