The Workflow

7 steps · click a step number to mark it done

Open Finevoice and have it ready before you start

Upload a silent video file to FineVoice’s “Video to SFX” section

Enter a descriptive prompt that explains what is happening in the video and the sounds you want (e.g., "people running on a beach, waves crashing, distant seagulls")

Add an optional negative description to exclude unwanted elements such as music, echo, or background noise

Click the “Generate” button and let the AI analyze the footage and create matching sound effects

Play the preview to confirm that the audio timing and realism meet your expectations

If needed, open the three‑dot menu, choose “Regenerate” or “Edit” to refine the sound effects

Download the final video with embedded sound effects (or download only the audio) for use in your project
