Workflow

Using HappyHorse 1.0

  1. Choose a supported generation mode in Playground.
  2. Add the required prompt and source or reference assets.
  3. Select output settings from the controls shown for that mode.
  4. Generate, then inspect the returned asset before reusing the settings through the API.

Practical guidance

  • Describe the subject, action or composition, environment, and visual direction in a clear order.
  • For image animation, describe the intended motion and camera behavior instead of repeating what is already visible.
  • Give each reference a clear role in the prompt, using the names inserted by the Playground.

Modes available on MachGen

  • Text to video - prompt alone; aspect_ratio sets the frame.
  • Image to video - one still as the first frame; output adopts the image aspect.
  • Reference to video - use one or more images as appearance references while the prompt drives motion and scene direction.

Input limits

  • Prompts up to 2,500 characters.
  • Images: JPG, PNG, BMP, or WEBP; each side at least 300 px; aspect between 1:2.5 and 2.5:1; up to 10 MB each.
  • Duration is an integer from 3 to 15 seconds; default 5.
Best results

How to get better HappyHorse 1.0 results

  • Choose the route based on the strongest source of control: text for exploration, an image for composition, or references for identity.
  • Describe one primary action and make the intended camera behavior explicit.
  • Use clean reference images with consistent subject details and minimal background clutter.
  • The current MachGen integration returns silent video, so plan sound as a separate production step.
