# Long videos and chapters > How to build a video of five minutes or more in Video: start from an outline, edit scene by scene, mark chapters, export chapter lines and split into videos you can render. Source: https://video.geenius.io/docs/long-videos/ 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 " - 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.
