## Description

Plan and build a finished beat-synced montage where cut placement serves the content, not just the metronome. Use for 卡点混剪, 卡点剪辑, 踩点视频, beat-sync montage, rhythm edit, 节奏剪辑, 音乐驱动剪辑, or when the user wants cuts that land on the beat.

# Beat Sync Montage

Use this workflow when the edit should be driven by music. The failure mode to
avoid is a metronome edit: every cut technically lands on a beat, and the result
still feels mechanical, tiring, or unrelated to what is on screen.

This workflow decides **what** to cut and **why**. It does not re-explain the
music tools, when you reach an execution step, follow `music-intelligence` for
`analyze_music`, `music_edit_plan`, and `sync_cuts_to_music`. Load it there.

This is a OpenChatCut-native workflow. Use the current project, source assets,
asset-frame inspection, AV/script context, and OpenChatCut editing tools.

## When to switch workflows

- Beat-synced photos on a locked, empty track → `music-intelligence` handles this directly with `music_image_plan`. This workflow is for video montage.
- One long source cut to speech rhythm → `long-video-to-shorts`.
- Many clips packaged as highlights without music driving the cut → `multi-clips-to-reels`.
- N distinct beat-synced variants from one pool → `batch-montage-variants`, using this workflow for each cut.
