What is Mirelo SFX v1 (Add Sound Effects)?
Mirelo SFX V2V is Mirelo's automatic sound effects generation model for video. The model analyzes visual content frame by frame and generates matching sound effects, ambient audio, and environmental sounds synchronized to the action on screen, producing contextually appropriate audio at an extremely low per-second cost. With per-second billing at $0.007 per second, a full 30-second video costs just $0.21 for complete SFX generation.
