clipwright-bgm
MCP tool to write BGM placement annotations to an OTIO timeline. Records BGM volume, fade, and ducking instructions as metadata on A2 Audio track clips, which clipwright-render realizes as a mix.
Overview
- Input: Timeline OTIO file, BGM audio file, output path, optional parameters (volume, fade, ducking)
- Process: OTIO manipulation only (no ffmpeg/external OSS). Adds BGM clip to A2 Audio track and writes clipwright metadata
- Output: New OTIO file with BGM annotations (input timeline immutable, M5)
