From Storyboard to Frame: HappyHorse 1.1 Image-to-Video Proof of Concept

Using the storyboard concept of "from text to image" as a thread, this demonstrates the minimal usable input for the happyhorse-1.1 image-to-video path: one first-frame image + one English motion description + duration and resolution. The author pipeline only accepts image_urls (exactly 1), an optional prompt, duration (3–15 seconds, default 5), and resolution (720p/1080p, default 1080p), so all visual information in this work is carried by the first-frame image generated by the pipeline, while the remaining fields control camera motion and output specifications. In terms of composition, the first-frame image selects a medium shot with narrative potential: the frame contains a clear subject, visible environmental layers, and directional lighting, making it easy for the model to maintain subject consistency and spatial relationships in subsequent frames; the prompt describes only motion, camera, and pacing, without restating the image content, avoiding conflict with the first frame. This structure is suitable for storyboard previsualization for short dramas and multi-shot narratives, motion-effect validation for e-commerce product showcase clips, and rapid concept test shoots in CG workflows. This model family also covers text-to-video, image-to-video, and reference-image-to-video; this entry follows the image-to-video branch, with a maximum single-segment duration of 15 seconds and up to 1080p. Long content needs to be generated in segments and then stitched together.
