Long videos and chapters

A long video is built in small, safe steps, not one big spec.

Start from an outline#

Create a scene video with an outline: a title, chapters and, for each scene, its lines or a brief and a duration. You get a valid skeleton: a title card, a card per chapter, content scenes and an outro.

Edit one scene at a time#

Add, update, remove, move and duplicate scenes, or copy scenes from another video. Each edit is atomic, validates the whole spec and names the scene when something is wrong. Every scene has a stable id, so edits do not drift when you move scenes.

Chapters#

A scene with a chapter name starts a chapter that runs to the next one. In the editor you see the chapters, and the chapter list exports as YouTube chapter lines with their start times.

Limits#

A scene video can have up to 300 scenes and 30 minutes. A single scene is at most 60 seconds.

Rendering a long video#

One render pass covers up to four minutes. Use split to make one video per chapter (same look, titled "<title> - 1." and so on), render each, and join them afterwards in the tool you like.

A good routine#

1. Outline with chapters of two to four minutes.
2. Write a chapter, check lint, preview.
3. Move on to the next chapter.
4. Split, render, join.
