Does my original video audio stay?

Yes. Source audio holds at full volume. SFX sum on top.

Can I preview sounds before assigning?

Yes. The play button next to each sound in the picker plays through your speakers without touching the marker.

Is there a marker limit?

Three on the free plan, unlimited with Pro.

What do the LUFS numbers mean?

Integrated LUFS is the loudness your mix averages to. YouTube and Spotify normalize around −14, Apple Music to −16, broadcast to −23. True Peak should stay at or under −1 dBTP.

Sound design editor

Sound Design Editor scores a video in your browser. Auto-places markers on beats, flashes and cuts; renders the clip's audio as a waveform you can drag markers on; accepts custom uploads; checks the final mix against broadcast loudness targets. The bundled pack covers shutters, whooshes, impacts, risers, sub drops and UI clicks.

Tips

Add a Shutter click on every cut, instant rhythm.
Pair a Sub drop with a black-cut marker in Deep Shell for a bigger hit.
The Master slider pulls the whole SFX bed down under dialogue.
If integrated loudness is above −14 LUFS, streaming platforms will turn it down. Bring it in range before export.
