Video-to-Audio models analyze video footage and generate matching sound effects, ambient audio, and foley sounds. In Automat Studio, these models power the SFX (Sound Effects) workflow, automatically creating soundscapes that sync to on-screen action.
These models are used in the SFX tab of Shot Studio to automatically generate sound effects that match the visual action in your shots.
