What makes it different
All-in-one audio generation combining dialogue, music, ambience and effects in a single mixed track
Scene-first workflow directing complete audio narratives rather than separate speech generation
Powered by ByteDance's Seed Audio 1.0 model for professional-quality audio generation
Multimodal input supporting text prompts combined with images or multiple audio references
Voice cloning capability using authorized audio references to guide vocal character and delivery
Focuses on motion design B-roll instead of stock footage or AI video clips
Motion design graphics created from descriptions rather than filmed or pulled from libraries
Eliminates the slowest part of video production: finding matching B-roll
Best for videos where words and numbers matter more than scenery
