Transform

Transform keeps motion separate from content. Instead of moving Text+, a logo or a Background inside the source node, you can place Transform after it and keep position, scale and rotation in one predictable place.

This separation becomes important in larger compositions. A Text+ can remain responsible for typography, while Transform handles animation and Merge handles compositing.

Transform can also move an already assembled mini-composition. Place it before Merge to move one element; place it after a group of Merge nodes to move the whole assembled block.

A separate Transform is a convenient place for whole-image motion, not a rule forbidding animation inside Text+. Letter-by-letter animation and typography belong to the text controls; a lower-third assembled on transparency can move as one image after its local Merge.

Changing Size is not the same as choosing a delivery resolution. Read the actual source dimensions, check frame borders and keep a separate canvas for the required output size. A Viewer zoom also does not resize the processed frame.
