How it works
Compose, approve, then animate
Step one composes your product into the scene as a still image. This is the cheap step, and it is where things go wrong if they are going to, so it is also where you get to look.
Step two animates only the stills you approved. That order is the whole design: the expensive part never runs on a frame you did not want.
The camera moves and the product holds still, which is what keeps a logo or a label from warping. It is also how real product films are shot.
How Chitrio does this: Every scene shows you the still first. Approve the ones that look right and skip the rest.
