HappyHorse 1.0 I2V on Alibaba animates a still image into native 1080p video with physics-accurate motion and identity-stable subjects.
PixVerse C1 turns text, images, paired frames, and references into film-oriented video. It supports clips up to 15 seconds, four resolution tiers through 1080p, and optional native audio, giving creative teams a single route from rough motion tests to polished short-form output.
The broader PixVerse C1 family covers text-to-video, image-to-video, first-to-last-frame transitions, and reference fusion. PixVerse C1 is designed for filmmakers, designers, agencies, and product teams that need controllable visual development without maintaining video-generation infrastructure.

PixVerse C1 supports text-to-video, image-to-video, transitions, and reference-guided generation. The current form uses an image and prompt, while related modes expose the other workflows. Outputs can run from 1 to 15 seconds at 360p, 540p, 720p, or 1080p.
PixVerse C1 fits filmmakers, technical artists, designers, agencies, and product teams creating shot concepts, campaign assets, product motion, or social video. It is especially useful when prompt-level direction and repeatable parameters matter.
Give PixVerse C1 separate instructions for subject action and camera movement, then add framing, lighting, atmosphere, and pacing. Keep the requested action realistic for the selected 1-15 second duration.
PixVerse C1 includes a generate_audio_switch option that is off by default. Turning it on requests native audio and changes the per-second rate.
PixVerse C1 exposes 360p, 540p, 720p, and 1080p, with an integer duration from 1 through 15 seconds. Available aspect-ratio control depends on the task form.
PixVerse C1 includes a seed parameter for controlled iteration. The same seed and inputs can improve repeatability, although generated-video systems may still show some variation.
Yes. Teams can test PixVerse C1 in the RunComfy model UI and then send the same exposed parameters through the HTTP API. This supports moving a validated request into an application or automation workflow.
PixVerse C1 is billed per generated second. Without audio: 360p $0.029/s, 540p $0.039/s, 720p $0.049/s, and 1080p $0.094/s. With audio: 360p $0.039/s, 540p $0.049/s, 720p $0.064/s, and 1080p $0.119/s. Your total depends on duration.
