Questions about Audio Tracks & Voiceover

Can I add music and voiceover to screen recordings?

Yes. Mix background music and voiceovers, adjust levels, and sync clips with the video timeline.

Does audio stay aligned after timeline cuts?

Audio clips are managed with the timeline so you can keep voiceover and music synchronized as scenes change.

How do I clean spoken audio before mixing?

Remove filler language from scripts with the free Filler Word Remover, then record or align voiceover in the editor.

Can I inspect duration before mixing tracks?

Check source duration with the Video File Inspector so music beds and voiceovers fit the final cut length.
