1How the two differ
HeyGen generates several takes of a shot and keeps the best, directing scene by scene without a timeline. Scenes AI animates each clip from an approved still and charges per generation; its pages do not describe redoing a clip.

3How a segment-based editor handles what splits HeyGen and Scenes AI
| Point | SceneMixer | Source |
|---|---|---|
| How an episode is built | An episode holds segments, and a segment holds every take generated of it | SceneMixer, what is inside a project |
| Whether a single shot can be redone | One segment is edited and regenerated without redoing the episode | SceneMixer, fixing one shot without redoing everything |
| Whether a finished cut can be partly replaced | After a segment changes, the episode is composited again; the earlier file stays until the new one replaces it | SceneMixer, compositing and sharing an episode |
Inclusion rule. Points on which the two editors differ and SceneMixer's guides describe its own handling. Order. The order points take on every editor page.
