So I’ve been coloring some shots, and I was wondering if it is at all possible to optimize more than one frame at a time. It must be somewhere, however I’ve not been able to find it!
Optimize is done on the selection. Simply select multiple frames and do the optimize command. Remember that the select tool’s Tool Properties setting has options for permanent selection (area selection that remains active over multiple frames of the same element) and for “apply to multiple drawings” which can be used together.
