Add sound effects

Sound design is the least-visible reason a video feels finished. It’s also tedious to place by hand — which makes it a perfect handoff.

What you need

• A composition that’s visually there but sounds empty (or just has music).
• A connected agent.

What to say

Do a sound-design pass — whoosh the scene transitions, click when the cursor taps, and a riser into the reveal at 0:18.

Or lighter:

This feels flat. Add subtle sound effects where things move.

What happens

The agent reads the composition’s timing — every transition, entrance, and punch-in has a known time — and places effects against those exact moments: sourced or synthesised audio clips, trimmed and leveled, landing frame-on with the motion they belong to. Then it balances the mix: effects sit under the voice, music ducks beneath both, and fades match the transitions they ride.

Make it yours

Each effect is an ordinary audio layer on the timeline — nudge one, lower one, delete one. Move an animation later and ask the agent to “re-sync the sound pass” — the effects follow the new timing.
