Integration with Video Pipeline
These tools combine well for autonomous video creation:
- Script → Write narration text
- TTS → Generate voiceover audio
- Images → Generate visuals/thumbnails
- 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
