Happy Horse - Video Edit

Try Happy Horse - Video Edit in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: happyhorse-1.0-video-edit HappyHorse 1.0 video edit performs local or global edits to a source video from natural-language instructions, optionally guided by up to 5 reference images, and can keep or regenerate the audio track. Output is 720P or 1080P, preserves the source aspect ratio, and matches the input duration capped at the first 15 seconds.

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.
