# How to Add Captions and Subtitles with Copilot

Copilot adds captions to videos directly in your development environment, which is valuable for developer content where technical terms need accurate transcription. Copilot can differentiate code terminology from regular speech and generate caption files in multiple formats -- SRT, VTT, ASS -- alongside the captioned video.

## Setup

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

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Transcribe and caption this tutorial video"
3. Copilot generates the transcription via ToolRouter
4. Burn in the captions: "Add subtitles with monospace font for the coding sections"
5. Save the captioned video to your project

## Example Prompt

```
Transcribe my coding tutorial video and add captions. Use a monospace font for code-related dialogue and a regular font for explanations. Bottom-center positioning.
```

## Tips

- Copilot can differentiate code terminology from regular speech in transcriptions
- Generate VTT files alongside the captioned video for HTML5 video players
- Caption your conference talk recordings for more accessible documentation
