How to change the label on a product in a video you already have
Tell Vizard Agent what the label says now and what it should say. It finds every shot the product appears in, maps the coordinates on the jar, tracks the label as it moves, flattens it to measure exactly how much space the old text occupied, and repaints the new name with shading that matches the curve.
What do you type into Vizard Agent?
Say both names and ask about every appearance. The failure usually isn't the hero shot. It's the two seconds in the background of a wide shot where the old name is small but still legible if somebody pauses. If you have the real artwork for the new label, send it: Vizard Agent can match a typeface from footage, but the design file is better.
Prompt
What does Vizard Agent actually do?
A label isn't text on a screen. It's text printed on a curved surface, lit from one side and moving through the shot, so swapping it convincingly is a tracking problem before it's a typography one. In the session behind this article it:
- Scanned the product clips for the shots the jar appeared in, read the labels as they were, and checked label visibility across both halves of the video.
- Mapped the coordinates on the jar and the label, tracked the label and swapped the text, then ran a hardened tracker across both product shots.
- Rectified the label, flattening the curve, to measure the old text's true extent, so the new name would fill the same space once curved again.
- Repainted the label with matched shading and checked it in the finished video, in context.
- Went looking for the old name elsewhere, found it small but legible in the tail shot, patched it, and verified the label held up in motion, not just on stills.
When does this not work well?
Repainting a label only works when there's enough label to repaint. Where the text is too small in frame, too motion-blurred or too briefly visible for Vizard Agent to resolve, the honest options are to hide that shot or re-film the product. Reflective surfaces and hands crossing the label make it harder, and ingredients or warnings are not a design choice.
Common questions
Why flatten the label first? Because a curve makes the old text look narrower than it is, and text sized against the curved image comes back the wrong width.
What about the small background shots? Vizard Agent checks them and tells you which cannot be fixed.
Is hiding a shot an option? Yes, and sometimes the right one. Vizard Agent will suggest it.
