Auto-proceed and looped playback

You can configure Demo Time to advance scenes automatically after a delay, and optionally loop back to the beginning of the act when it reaches the end.

Scene auto-proceed

Set autoAdvanceAfter on a scene to move to the next scene after the configured delay (in seconds).

JSON

demo.json

{
  "$schema": "https://demotime.show/demo-time.schema.json",
  "version": 3,
  "scenes": [
    {
      "title": "Intro slide",
      "autoAdvanceAfter": 5,
      "moves": [
        {
          "action": "openSlide",
          "path": ".demo/slides/slide-1.md"
        }
      ]
    }
  ]
}

YAML

version: 3
scenes:
  - title: Intro slide
    autoAdvanceAfter: 5
    moves:
      - action: openSlide
        path: .demo/slides/slide-1.md

Act-level loop

Set loop: true at the root of the act file to restart from the first scene when the act reaches the end.

{
  "$schema": "https://demotime.show/demo-time.schema.json",

Status bar automation indicator

When auto-proceed is active, Demo Time shows an automation indicator in the status bar.

• It reflects whether automation is running or paused.
• It shows loop status when act looping is enabled.
• It shows a countdown while waiting to advance.
• You can pause and resume auto-proceed directly from the indicator.
