Happy Horse Video Edit

We’ve added Happy Horse Video Edit so you can transform existing clips with simple text instructions.

Why This Matters

• Faster iteration: Start from an existing video and apply targeted edits instead of regenerating from scratch.
• Better style control: Add up to 5 reference images to steer look and identity.
• Audio flexibility: Keep original audio or let the model regenerate it automatically.

What’s New

• New edit model: happy-horse-video-edit
• Input support for:
  • Source video URL
  • Prompt-based edit instructions
  • Up to 5 reference images
  • Audio mode (origin or auto)
• Duration compatibility:
  • Input videos from 3-60 seconds
  • Output is capped to the first 15 seconds for longer inputs

Pricing

• 1080p: $0.364 / second (includes platform markup)
• 720p: supported by API (internal default currently uses 1080p for best output quality)
