How does Happy Horse AI work?
Enter a text prompt (up to 2000 characters) or upload a reference image. Choose between text-to-video, image-to-video, or first-and-last-frame modes. Select resolution (480P or 1080p), duration (up to 4 seconds), and aspect ratio (16:9 by default). The model processes the input and returns a video with optional synchronized audio. Each generation consumes credits from your account.
