Export Sequence Review Frames
export_sequence_review_framesExport 2-24 evenly spaced, verified frames from an active sequence range in one round trip so you can visually review edits before a full video export.
Instructions
Export 2-24 evenly spaced, file-verified frames from an active-sequence range in one bridge round trip for visual review. If Media Encoder still capture cannot restore sequence In/Out, remaining frames are not attempted and the call fails. Still capture does not verify temporal animation, playback, audio, or editorial quality; PNG frames keep the sequence's transparency (straight alpha), so composite them over black before comparing with a video export.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| output_dir | Yes | Existing directory where review_001.png through review_NNN.png will be written | |
| end_seconds | No | Optional positive range end in seconds (default: sequence end) | |
| frame_count | No | Number of evenly spaced frames to export (default: 6; minimum: 2; maximum: 24) | |
| start_seconds | No | Optional non-negative range start in seconds (default: sequence start) | |
| idempotency_key | No | Optional client-chosen key (1-128 chars of A-Z a-z 0-9 . _ : -) for this intended edit. Pass a fresh key per edit and reuse it only when retrying that same edit, for example after a client-side timeout. A repeat with the same tool, key and arguments is not run again: while the first call is running it fails with IDEMPOTENCY_IN_PROGRESS (poll get_last_operations); after it finished it returns the original outcome marked replayed. A definite failure with nothing applied (receipt outcome not_applied) may be retried with the same key. Reusing a key with different arguments fails with IDEMPOTENCY_KEY_REUSED. Scoped to this MCP session (the stdio server process, or the HTTP server process when Streamable HTTP is stateless per request) and held in memory only (200 keys, 1 hour); it does not survive a restart or reconnect. Read-only invocations are never deduplicated. | |
| 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. | |
| 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. |
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. |
