1080p Cinema-Quality Output
HappyHorse 1.0 generates true 1080p output (also 720p) across five aspect ratios — 16:9 widescreen, 9:16 vertical, 1:1 square, 4:3, and 3:4. One model covers cinema, mobile, and feed-native formats without round-tripping through upscalers.

Joint Audio + Video in One Pass
Most AI video tools generate silent clips and rely on separate models for dubbing, lip-sync, and sound effects. HappyHorse 1.0 takes a different approach: a single unified Transformer denoises video and audio tokens in the same forward pass. Dialogue, ambient sound, and Foley effects emerge already aligned to the visual content — footsteps land on the right frames, ambient noise responds to camera cuts, mouth shapes match the audio.
