How to catch b-roll that shows something similar but not the thing you named
Ask Vizard Agent to verify what each clip actually contains rather than trusting the search that found it. Stock libraries match the shape of a request, such as food being sliced or a person typing, so a near neighbour of your subject comes back looking right. When repeated searches keep missing, the escalation is to generate the specific shot instead.
What do you type into Vizard Agent?
Name what would make a clip wrong, not just what would make it right. Saying which near neighbour you don't want is more useful than another adjective, because that is exactly what the library is going to offer. Name the subject as specifically as you would to someone who knows the field: the dish, the species, the model.
Prompt
What does Vizard Agent actually do?
Stock titles and tags describe a clip generously. A clip called "chef slicing meat" is exactly as true of the wrong meat as the right one, so Vizard Agent looks at the frames instead of the titles, and generates the shot when the library keeps missing. In the session behind this article it:
- Worked on a ten-second opener that needed one very specific dish, and researched the subject first so it knew what it was looking for.
- Searched stock and downloaded the candidates. The first search returned a perfectly plausible clip, and the user spotted that it was the wrong thing.
- Looked at frames from each candidate rather than reading the titles, compared what was shown with what was asked for, and searched again with a narrower term when it didn't match.
- Generated the shot when the library kept missing, since two failed searches are usually a sign the library doesn't hold it.
- Re-assembled the opener with the correct footage and reviewed the finished frames to confirm the fix landed.
When does this not work well?
Some shots don't exist and can't be convincingly generated. A rare object, a specific real place, or a real person doing a particular thing are all cases where the honest answer is to change the line rather than keep hunting for the picture. In a fast cut a near miss may genuinely not matter, and very specialist fields need someone who knows to check.
Common questions
How many searches before generating? Usually two. Vizard Agent will suggest the switch rather than looping.
Does the clip title help? Barely. Vizard Agent treats titles as a hint, not evidence.
Is a near miss ever fine? Yes, in a fast cut. Tell Vizard Agent when you are happy to accept one.
