Mostly free; Isolate Voice 3 credits

A clean mix makes generated footage feel finished. Most of it is free and takes a few minutes.

Organise the tracks

Use Add audio track to keep Music, Sound effects and Voiceover on separate tracks. In the Mixing Console (toolbar, or Alt+M) give each track a role: Voice (dialogue), Music, SFX.

Duck the music under dialogue

On the music track, turn on Duck in the Mixing Console (or right-click the track header → Duck under dialogue) and choose how far to drop it. The music now dips whenever someone speaks.

Shape each clip

Select a clip → Inspector → Audio: Volume, Pan, Fade In / Fade Out, Crossfade from previous clip, plus Noise reduction, Equalizer and Compressor. Short fades on every cut stop clicks.

Clean up voices

Isolate Voice (3 credits) strips background noise and music from speech. Fix dialogue corrects wrong words (see "Dialogue that lands").

Hit a loudness target

Loudness Normalization has presets for where the film is going:

PresetTarget
Streaming−14 LUFS
Podcast−16 LUFS
Broadcast−23 LUFS
Cinema−24 LUFS

Choose one and Normalize All Clips. The Broadcast figure is the EBU R 128 standard. Note that the Mixing Console's MASTER fader only changes how loud the preview plays, not the export.
