Where it shines
The 1.1 release doubled down on the two hardest problems in generative video: physics and motion coherence. Water, hair, cloth and smoke behave believably; camera instructions like 'slow dolly-in' or 'aerial orbit' translate into real cinematography; and quality holds to the last frame instead of melting midway.
Stylistically it covers photorealism, cinematic looks, anime and illustration. Like all current video models it's weakest at rendering long readable text — design your scenes around imagery, not typography.
Prompting HappyHorse 1.1 t2v
Follow the Subject + Action + Setting + Lighting + Camera + Style skeleton. Concrete nouns and one clear action per clip outperform sprawling multi-event prompts. Every public video on txtovid ships with its full prompt, so the community feed doubles as a living prompt library.
