# Premiere Captions

Use supplied timed text as the source of truth. The current server does not provide trustworthy speech transcription by itself.

## Required server profile

Start or restart the MCP server with `MCP_TOOL_PROFILE=captions`. The default `standard` profile also contains this workflow, but `captions` is the smaller dedicated surface.

## Workflow

1. Verify the host and target sequence with `premiere_ping`, `premiere_get_project`, and `premiere_get_timeline`.
2. Obtain a valid SRT file with segment timestamps. If only audio exists, request or generate a timestamped transcript with a separate transcription system; this server does not claim to transcribe speech.
3. Fix line wrapping in the SRT before import: keep at most two lines, avoid single-word orphan lines, and reject overlaps or non-positive durations.
4. Resolve the active sequence index with `premiere_get_sequence_list`, duplicate it with `premiere_duplicate_sequence`, identify exactly one new copy and its ID, and activate that copy with `premiere_set_active_sequence`. Require `verified: true` with that ID, then re-read the sequence list and stop unless `activeSequenceID` matches. Leave the source untouched as the recovery boundary. A timeline snapshot or saved sequence version is audit data only, not a whole-sequence restore point.
5. Call `premiere_add_subtitles_from_srt` on the duplicate. Require `verified: true` and an exact caption-count match.
6. Call `premiere_get_captions` and compare every readable segment's text, start, and end against the source. Stop on a mismatch.
7. Run `premiere_validate_closed_captions` for structural QA. Reconfirm the duplicate's active ID, export sidecar captions with `premiere_export_captions` using that ID as `sequence_id`, then verify through the filesystem that the sidecar exists, is non-empty, and parses to the expected segment count. If filesystem verification is unavailable, report the export as unverified.

## Guardrails

- Preserve source language, names, numbers, and punctuation; flag uncertain words instead of inventing them.
- Request a visual title-safe review; the CEP caption API cannot verify styling or on-screen placement.
- CEP caption styling, speech alignment, and in-Premiere segment splitting are explicitly unsupported because they cannot be mutated and read back safely. Style manually or use a verified MOGRT-based burned-in workflow.
- Structural validation is not FCC certification. Report caption count, overlaps, warnings, and errors; do not infer transcription accuracy, timeline coverage, reading speed, or placement.
