How the product takes the car's place
Before the render, the maker looks at your photo. If it is a vehicle, the vehicle does the stunt. If it is anything else, the maker names it in a few words, such as “crispy chicken sandwich in a black bowl of fries”, and renders that object as the hero of every shot on Seedance 2.0 Mini, using empty frames of the same ramp set.
If the check is unsure, it treats the photo as a vehicle. A clean product shot avoids that.
