How to stop the stock clips' own sound getting into your mix
Tell Vizard Agent to mute the source clips unless their sound is doing something. Downloaded and stock footage carries whatever was recorded on the day, like traffic, a room or a stranger talking, and it arrives under your narration by default. It checks what each clip actually holds, mutes the ones adding nothing, and measures whatever survives against the voice.
What do you type into Vizard Agent?
Give Vizard Agent the default, then ask for the exceptions. "Mute the stock footage sounds" is already a complete instruction, and asking which clips are worth un-muting turns a blanket rule into a decision about each one. Say what the mix is for, too: usually that the voice leads.
Prompt
What does Vizard Agent actually do?
Nobody chooses the ambience in a stock clip. It comes with the file, and several clips each bring their own room. The muting itself is just a rendering decision; the useful work happens before it, in finding out what's actually on each audio track. In the session behind this article it:
- Measured each clip of a narrated video built from mixed sources and checked whether it had audio at all.
- Checked the footage for spoken content it would be a shame to lose, before applying any blanket mute.
- Listened to what the native audio actually was, since a clip can carry a full track of nothing but air conditioning, then muted the clips whose sound added nothing and kept any whose sound carried the moment.
- Measured the narration's loudness and the music separately, and set the duck level by comparing an active narration window against the music.
- Rendered with the source clips muted and checked the waveform for gaps or an abrupt ending.
When does this not work well?
Muting by default is the wrong rule when the footage itself is the point, and Vizard Agent will say so. Documentary material, reaction clips and anything where the recorded sound is evidence all want their native audio kept, so there the default should be reversed. Action footage often needs its impact sound too.
Common questions
Will it mute everything? Only what adds nothing. Vizard Agent checks each clip first.
What if someone speaks in a clip? Vizard Agent looks for that before muting, and keeps it.
Will the video sound too dry? It can. Ask Vizard Agent to add one deliberate bed instead.
