Preview Motion Graphics Demo
preview_motion_graphics_demoPreview how existing project items assemble into a motion-graphics demo before applying changes; requires exact confirmation token and never creates assets, imports files, or edits Premiere.
Instructions
Preview a contained motion-graphics demo assembly from existing project items. It never creates demo assets, imports files, creates a sequence, or changes Premiere; apply requires an exact confirmation token.

}
}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| sequence_id | Yes | Exact ID of an existing empty destination sequence. It must be active at apply time. | |
| asset_item_ids | Yes | Exact existing project-item node IDs in playback order; external media paths are deliberately not imported by this workflow. | |
| transition_name | No | Transition name; defaults to Cross Dissolve. Use none to disable transitions. | |
| audio_track_index | No | Empty destination audio track index, default 0. | |
| video_track_index | No | Empty destination video track index, default 0. | |
| expected_cep_target | No | Optional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard. | |
| clip_duration_seconds | No | Planned spacing between asset starts; defaults to 5 seconds for a motion demo and 4 seconds for spots. | |
| expected_project_path | No | Optional absolute saved-project path. Every generated CEP command refuses before its body when the active project differs or is unsaved. UXP commands refuse this CEP-only guard; local-only tools do not inspect Premiere. Omit to keep existing behavior. | |
| transition_duration_seconds | No | Transition duration, default 0.75 seconds for demos and 0.5 seconds for spots. |
Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| ok | Yes | Whether the tool completed successfully. | |
| data | No | Tool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it. | |
| tool | Yes | The registered MCP tool name. | |
| error | No | Failure detail when ok is false. | |
| receipt | No | Versioned common mutation receipt; success never implies rendered verification. | |
| idempotency | No | Present when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again. |
