# How to Isolate Film Dialogue with Copilot

Copilot isolates film dialogue within your IDE, enabling a streamlined post-production pipeline. Chain dialogue isolation with transcription for automated subtitling, and batch-process scene files for large projects without leaving your development environment.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Isolate dialogue from this film audio file"
3. Copilot processes the audio and returns the dialogue track
4. Ask: "Process the remaining scene files in this directory"
5. Download all isolated dialogue tracks

## Example Prompt

```
Extract the dialogue from this video file for automated subtitling processing.
```

## Tips

- Chain with audio-transcriber to go from film audio to subtitles in two steps
- Batch-process scene-by-scene for large projects
- Isolated dialogue makes automated transcription significantly more accurate
