Joint Video + Audio Synthesis
Stop syncing by hand. Dialogue, ambient sound, and foley are all generated together, perfectly in phase.
Happy Horse 1.0's core architecture treats video and audio as one unified sequence. This means no more stitching audio tracks or fighting with cross-attention modules. Dialogue, ambient sounds, and foley effects are generated simultaneously in a single pass.
