Overview
Reach for this family when a clip has to match material that already exists — a character you generated earlier, a room you have established, a look you would rather not have reinterpreted. Its variants differ in how much of that material they will take: nothing at all, a still, or a whole set handed over at once. It is the natural step after an image model, since the frames you kept become the input instead of a description of one.

Variants in this family
The question is how much of the shot already exists. With nothing to hand over, the text variant works from your description alone. Attach a picture and you are asking the model to continue something you have already made rather than invent an equivalent. Give it a set and the pictures act as a brief for the cast and the setting, while the action stays yours to write.
