ItemlumeProduct videos / QUESTION GUIDE
Why does the number of products change during an AI multipack video?
Count the units in the opening, during movement and after occlusion. A generated multipack may merge two items or introduce another as the camera moves. If the video explains supplied quantity, every visible transition must preserve that count; an accurate opening frame alone is insufficient.
Define the counted set
Record the actual pack quantity and distinguish merchandise units from props or empty display packaging. Choose a starting image in which the count is inspectable. Overlapping identical items can make it hard to tell whether one has disappeared or is merely hidden.
For an illustrative three-jar bundle, give the review a simple positional map: left, center and right. The map is for human inspection, not an Itemlume object-tracking capability. Use the actual supplied variants as the source of truth.
Review count at transitions
| Moment | Check | Failure example |
|---|---|---|
| Opening | All supplied units identified | Extra jar already present |
| Camera move | Distinct units remain connected | Two jars merge |
| Occlusion | Hidden unit has a plausible path | New unit appears from nowhere |
| Ending | Pack count still correct | One jar permanently missing |
A temporary overlap is not automatically a defect. Follow the unit’s position before and after the overlap. If the relationship cannot be understood, simplify the action.
Keep the bundle motion restrained
In Product videos, plan one movement around an approved bundle first frame. Avoid asking every identical object to spin, jump and exchange positions in a short shot. A subtle camera move can preserve the pack explanation better than choreography. Read the proposed storyboard before confirming generation.
After generation, inspect the whole clip, not just sampled attractive frames. Itemlume does not provide an automatic object-count guarantee. Use actual bundle footage when a precise inventory demonstration cannot be reviewed confidently.
Check the final quantity message
Read captions and nearby purchase text with the clip. A decorative scene containing extra jars can contradict a two-pack listing even if its animation is smooth. Remove unsupported extras or choose a shot with an unmistakable supplied set. Do not fix a disappearing unit by changing the quantity claim.
Use bundle planning for the source image and occlusion review for hidden moments. Preserve the count map and review result with the released video.
