How does the auto-placement work?

It listens for audio peaks and beats, watches for white flashes and hard cuts, then drops markers at the strongest moments. High-likelihood picks get a second-pass refinement from an on-platform vision model.

Can I change the sounds after generation?

Yes. Every marker is editable, swap the sound, change the category, drag to retime, delete, or add new ones.

Does it need an audio track on the video?

No. If the video has no audio, it uses white-flash and cut detection only. With audio, the placement gets significantly better.

How many markers will it add?

About 10 to 15 per minute by default, enough to cover the obvious hits without crowding the timeline.

Auto SFX

Auto SFX places sound effects on a video automatically. It runs four signal passes, audio onsets, beat detection, white-flash frames, hard cuts, scores each candidate moment, keeps about 10 to 15 markers per minute, and hands over an editable timeline. Top-scored picks get a second-pass refinement from an on-platform vision model. Loudness metrics follow ITU-R BS.1770-4.

Tips

Regenerate with a different density if the first pass feels crowded or thin.
Auto markers are tagged, manual markers you add afterwards survive a regenerate.
Watch the SFX-vs-program chip: if the SFX bed is more than 6 LU above the dialogue, pull the master down.
For streaming, aim for −14 LUFS integrated and ≤ −1 dBTP true peak.
