If your team does not have a separate audio editor, this matters. Voices, room tone and effects are generated alongside the picture, so lips, footsteps and impacts are meant to land without a trip to another tool. That helps with a talking-head explainer, a voiced product demo, or a social cut that would otherwise go out silent. If you already have a voice track, upload it as an audio reference and let it set the rhythm.
