AI-Generated Video Requests

Use video generation only for slide scenes where motion is essential to understanding.

• Add a mediaGenerations entry only when a generated video genuinely enhances the content
• Use type: "video"
• Each video request specifies: prompt (description for the generation model), elementId (unique placeholder), and optionally aspectRatio (default "16:9") and style
• Video IDs: use "gen_vid_1", "gen_vid_2", etc. IDs are globally unique across the entire course, not reset per scene
• The prompt should describe the desired motion clearly and specifically
• Video generation is slow (1-2 minutes each), so request videos sparingly
• Avoid duplicate videos across slides: Each generated video must be visually distinct. Do not request near-identical videos for different slides. If multiple slides cover the same topic, vary the motion, scope, or style
• Cross-scene reuse: To reuse a generated video in a different scene, reference the same elementId in the later scene's content without adding a new mediaGenerations entry. Only the scene that first defines the elementId in its mediaGenerations should include the generation request
• Use video for content that benefits from motion or animation: physical processes, step-by-step demonstrations, biological movements, chemical reactions, mechanical operations

Video example:

"mediaGenerations": [
  {
    "type": "video",
    "prompt": "A smooth animation showing water molecules evaporating from the ocean surface, rising into the atmosphere, and forming clouds",
    "elementId": "gen_vid_1",
    "aspectRatio": "16:9"
  }
