Read the story at three levels
A scene groups a part of the story around its setting or action. A cut is a unit you work with in the sequence. Shots describe the framing and camera direction inside that cut.
Start with the scene when the story needs to change. Open the cut when you want to change what happens in one part of the sequence. Review its shots when the action is right but the camera direction needs work.
Keep references with their elements
Characters, outfits, locations, and objects carry information that can be reused across the project. Attach a reference to the element it describes, rather than assuming every uploaded image is used everywhere.
Source materials are the documents, images, and other references you brought into the project. Assets are media you can select and use. A file appearing in either list does not mean it has already been applied to the timeline.
Separate the plan from the selected result
A cut can have several generated takes. The selected take is the one used in the edit; an older result can remain in history without appearing in the sequence.
Editing a description, changing a style, or replacing a reference does not rewrite a completed video. Review the new generation settings, generate when needed, and select the result you want to use.
