HappyHorse 1.0 FAQ
Use HappyHorse 1.0 when the input material may change from run to run. It can start from text, one image, several reference images, or one existing video, so it is useful when you are still deciding whether the concept is best driven by a prompt, a still, or source footage.
On Rivya, HappyHorse 1.0 supports text-to-video with no media, image-to-video with one image, reference-to-video with 2 to 9 images, and video editing with one video plus up to 5 images. Those limits are enforced by the workspace, not just described on the page.
The first decision is the media mix: no media, one image, several images, or one video. After that, choose 720p or 1080p, set a 3 to 15 second output duration, and only use aspect ratio or audio handling where that workflow actually supports it.
HappyHorse 1.0 starts at 28 credits for 720p and 48 credits for 1080p. It is easiest to justify when you need to test a real motion direction or video edit, not just create a batch of low-value clips.
Avoid mixing too many intentions in one run. A single image works as a direct image-to-video start, several images work as references, and an uploaded video becomes the main source. If you attach a video, keep image references to 5 or fewer.
Start with the media type that best represents the idea: no media for a prompt-only clip, one image for a still-led motion test, several images for reference control, or one existing video for editing.
You can set resolution, duration, and the reference media mix. Aspect ratio is available for text-to-video and multi-image reference runs, while audio handling applies to video editing.
HappyHorse accepts up to 9 images when no video is attached. If you attach a video, use only one video and no more than 5 images. The source video must be a short clip in the supported duration range.
The page is public, but creating the actual video requires sign in. Current public pricing starts at 28 credits for 720p and 48 credits for 1080p, so choose the media mix and resolution before spending credits.
Stay here while you are testing the first clip direction or edit setup. Move into the full Studio when you need saved takes, repeated variations, or a longer production thread around the same source material.
