| Camera point | SceneMixer | Source |
|---|---|---|
| Shot sizes and angles in the docs | Each numbered shot in a segment carries a framing change, written by the storyboard step | SceneMixer, AI storyboard generator page |
| A negative prompt | Negative wording is advised against: the guide says to describe what is there, because a named absence tends to be drawn | SceneMixer, say what is there guide |
