Setting Parameters

To make any element dynamic:

• Select the element on the canvas
• Open the Styles tab in the right sidebar
• Switch to the API sub-tab (next to Design and Animate)
• Toggle Parameterize on
• Set a unique Parameter ID

The API tab also shows usage examples for that element. A green dot appears on the API tab when the selected element has parameterization enabled.

• Trim Start - Set the start time using {parameterId}.trimStart
• Trim End - Set the end time using {parameterId}.trimEnd
• Muted - Control audio with {parameterId}.muted

  "bgVideo.trimStart": 5,
  "bgVideo.trimEnd": 15,
  "bgVideo.muted": false,
  "bgVideo.loop": true
