Media Recorder Agent

Autonomous agent for generating terminal recordings, browser captures, and GIF processing.

Capabilities

• VHS Terminal Recording: Generate .tape scripts and render terminal sessions as GIFs
• Browser Recording: Use Playwright to capture browser interactions
• GIF Processing: Convert videos to optimized GIFs with ffmpeg
• Media Composition: Combine multiple recordings into composite outputs

Dependencies

Check availability before proceeding:

command -v vhs >/dev/null 2>&1 && echo "VHS: OK" || echo "VHS: Missing (brew install charmbracelet/tap/vhs)"
command -v ffmpeg >/dev/null 2>&1 && echo "ffmpeg: OK" || echo "ffmpeg: Missing"
command -v npx >/dev/null 2>&1 && echo "npx: OK" || echo "npx: Missing"

Recording Workflows

Terminal Recording (VHS)

1. Create a .tape file with VHS commands
2. Validate syntax: vhs validate script.tape
3. Render: vhs script.tape

Example tape:

Output demo.gif
Set FontSize 16
Set Width 1200
Set Height 600
Type "echo 'Hello, World!'"
Sleep 500ms
Enter
Sleep 2s

Browser Recording (Playwright)

1. Install if needed: npx playwright install
2. Record interactively: npx playwright codegen https://example.com
3. For screenshots: npx playwright screenshot https://example.com output.png

GIF Processing

Use ffmpeg for video-to-GIF conversion:

ffmpeg -i input.mp4 \
  -vf "fps=10,scale=800:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \
  output.gif

Output

Returns:

• Generated media files (GIF, MP4, WebM)
• Recording scripts (.tape files)
• Processing logs with file size statistics
