## [Alibaba: HappyHorse 1.0](https://ailoot.ai/models/en/alibaba-happyhorse-1-0/)

Alibaba HappyHorse 1.0 creates short videos with sound from text, a first image or up to nine reference images. Its generation modes produce 3–15-second MP4 at 24 fps in 720p or 1080p. A separately named 1.0 video-edit profile revises supplied footage with optional visual references and its own limits.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Alibaba HappyHorse 1.0 is a video-creation edition with named text-to-video, first-frame image-to-video and reference-to-video profiles. The maker describes physically convincing motion, semantic understanding and audio-visual synchronization as its creative focus. Its reference profile can use up to nine images to guide subjects and scenes. The useful artifact is a short clip with sound: a new scene, an animation from a prepared opening still or a reference-guided character or product shot.

For a text scene, define the subject, setting, action and camera, with the intended sound. For a tabletop scene, show a small model sailboat moving through a shallow water tray while the camera follows it at table height. The review can then check the boat’s form, the scale of the scene, water movement and the relationship between motion and sound. A focused action is easier to assess than a dense sequence whose essential moment is not clearly stated.

For first-frame generation, use a still whose subject and composition already fit the desired opening. Describe the motion that follows and the camera’s path. The maker’s exact 1.0 image profile accepts text and image input, while its generation matrix identifies this as first-frame image-to-video. Prepare the crop and visible product or character details before the shot is generated. Check whether those details remain recognizable through movement rather than judging only the opening frame.

Reference-to-video combines the people, products, style or setting shown in visual sources into a newly described scene. The exact 1.0 reference model page documents up to nine images. Assign their roles in the brief and describe how the subject should act within the scene. A product showcase can distinguish the item reference from the surrounding location or visual style. The maker’s stability emphasis is a goal for review: compare the subject, markings and placement with the actual references throughout the clip.

The 1.0 family also has a separately named video-edit profile for style changes and local or broader revisions of existing footage. That profile takes exactly one source video and zero to five reference images, rather than the nine-image reference-generation arrangement. State what should change and what should remain, such as changing a garment while retaining the person, movement and background. The editing result needs comparison with the complete source clip, not only a frame that shows the intended replacement.

The exact 1.0 edit guide accepts MP4 or MOV source footage, recommends H.264, and permits source duration from three to sixty seconds. It lists a 100 MB maximum, a shorter side of at least 360 pixels, a longer side no greater than 4,096 pixels, proportions between 1:2.5 and 2.5:1, and input frame rate from eight to sixty fps. Output edits are limited to three to fifteen seconds: sources of fifteen seconds or less retain their duration, while longer sources use only the first fifteen seconds. Trim the intended passage before preparing the edit when an important action occurs later in the source.

The edit profile’s optional reference images have their own twenty-MB limit and JPEG/JPG, PNG or WEBP format requirements, with both dimensions at least 300 pixels and the same documented proportion range. The guide also distinguishes automatic audio treatment from keeping the original audio. Prepare the reference that identifies the intended change and choose how the source sound should relate to it. These are specific 1.0 editing-profile controls, separate from the new-scene generation modes.

For the 1.0 generation modes, the maker’s exact matrix lists 720p or 1080p, three to fifteen seconds, MP4 at 24 fps and audio. The edit profile also outputs 720p or 1080p within its fifteen-second limit. The documented task flow returns a processing identifier first and the completed video location after success; result locations are valid for twenty-four hours. Retain the actual clip, prompt and references when preparing a production edit, and inspect the returned framing, duration and sound together.

HappyHorse 1.1 adds a 480p generation option and named improvements in visual detail, motion and cross-clip consistency. Those later generation claims are not a fixed-revision guarantee for the 1.0 profile. The useful 1.0 preparation follows the selected mode and its actual source materials. Review identity, contact, object geometry, text and sound, then make the next correction concrete. For an edited clip, also check that important original details outside the requested change remain suitable for the intended scene.

Errors and next steps

| Response | Condition | Next step |
| --- | --- | --- |
| Response404 · `not_found_error` | ConditionVideo access is unavailable, or this video ID was not found. | Next stepCheck video access. For an existing video, use its original public ID and the same API key. |
| Response401 · `authentication_error` | ConditionThe API key does not match the authenticated account. | Next stepCheck your API key and account access before submitting. |
| Response400 · `invalid_request_error` | ConditionThe request could not be read, or the download index is invalid. | Next stepCorrect the request body. For a download, choose an output index returned by the original task. |
| Response422 · `price_unavailable` | ConditionThe selected video configuration cannot be priced. | Next stepChoose a supported video configuration and complete its required options before submitting a corrected request. |
| Response422 · `invalid_request_error` | ConditionA video input or original continuation task is invalid. | Next stepUse valid HTTPS inputs. For continuation, use your completed original public video ID with the same API key. |
| Response402 · `billing_error` | ConditionThe available balance or limits do not allow a reservation. | Next stepCheck your available balance and limits before sending a new request. |
| Response503 · `server_error` | ConditionVideo verification, storage or service access is temporarily unavailable. | Next stepWait for service availability. If you already have a video ID, check that original task instead of creating another generation. |
| Response503 · `result_pending_check` | ConditionThe original video result and charge need checking. | Next stepKeep the returned video ID and check that task. Do not send a replacement generation request while it is being checked. |
| Response503 · `owned_result_unavailable` | ConditionThe existing video download is temporarily unavailable. | Next stepCheck the same video task later and download its existing output. A new generation creates a separate operation. |
| Response409 · `video_not_ready` | ConditionThe video content has not been published. | Next stepCheck the original task status. Download after it reports completed; if it reports failed, follow its charge-check notice. |
