Integration with Video Pipeline

These tools combine well for autonomous video creation:

1. Script → Write narration text
2. TTS → Generate voiceover audio
3. Images → Generate visuals/thumbnails
4. Combine → Use ffmpeg or video editor

Example Workflow

1. Generate narration: /austn-tools tts "Welcome to austnomaton..."
2. Generate thumbnail: /austn-tools image "Robot mascot, friendly, digital art"
3. Record screen session with browser automation
4. Combine audio + video with ffmpeg
5. Export final video

Output Locations

Save generated content to:

• Audio:

  content/audio/

• Images:

  content/images/

• Videos:

  content/videos/

Connection Details

• Services route to local GPU via Tailscale
• Image generation connects to

  100.68.94.33:8188

  (ComfyUI)
• If generation fails with "TCP connection" error, the backend server isn't running

Verified Working (2026-02-02)

• ✅ TTS - Generated 8.4s audio in 6.9s
• ❌ Images - Failed (ComfyUI server not running)

Notes

• Services depend on Austin's local GPU being online
• No API keys needed - it's Austin's own infrastructure
• TTS has "Share Link" that lasts 7 days
• Gallery publish is optional and temporary (10 min)
• Large batches may take time depending on GPU load
