Every film has a few things that keep coming back and have to stay consistent: the lead's face, the street the story happens on, that pair of running shoes. Mixed in among the dozens of images in the Image column, they take a while to dig out every time you want to compare against one. Tag them as Key elements in DOTV's storyboard and they all gather into the small block at the top of the side column, there whenever you need to check — character consistency in an AI video comes down to being able to line every shot up against these few images fast. This section covers what to tag, how to tag, and how to use the block.
