How to make a video where every sound matches something on screen
Tell Vizard Agent there is to be no music at all and that every sound must correspond to something visible. It builds the effects scene by scene, reviews the frames again for actions it has not covered, adds those, and checks the finished waveform for the silences a missing effect leaves behind.
What do you type into Vizard Agent?
Say it three ways in the same sentence. "No music" gets interpreted generously by Vizard Agent and everyone else, since a soft pad under a scene doesn't feel like music, so the version of this instruction that actually holds is the one that closes every door at once. If you want room tone, say so.
Prompt
What does Vizard Agent actually do?
A music bed hides everything underneath it. Take it away and a missing effect isn't covered, it's a hole. The first pass covers the obvious actions and leaves the small ones silent, so Vizard Agent reviews the frames a second time looking for movements with no sound attached yet. In the session behind this article it:
- Checked the available tools and their costs, read the template guidance, and built the scenes of an animated short and their sound in parallel.
- Checked each scene's duration and format, extracted frames and reviewed them scene by scene at higher time resolution.
- Built the missing effects found that way, such as a brake and a wheel click, then reviewed the detailed frames again for anything still uncovered.
- Normalised every scene's format and resolution, added title graphics, joined the scenes and aligned every sound effect and Foley layer to the picture.
- Measured the integrated loudness, combined picture and sound, and checked a visual QC grid and an audio waveform for gaps before delivery.
When does this not work well?
Some videos genuinely need a music bed, and taking it away makes them thinner, not purer. Anything carried by mood rather than visible action fights this rule, and Vizard Agent will say so rather than deliver something hollow. Long static shots, talking-head footage, very fast cutting and muted autoplay are all poor fits too.
Common questions
Does "no music" include ambience? Your call. Tell Vizard Agent whether room tone counts as music.
How does it find missing sounds? Vizard Agent reviews the frames again looking for actions with no effect attached.
Can it do this for filmed footage? Yes. Vizard Agent adds effects to what is visible in your own shots.
