Improved Captions Editing
Please improve captions editing by allowing us to copy/paste, selecting and moving multiple captions at once, easily create caption clips that can be inserted in the middle of a scene, etc. The caption features in Premiere are extremely limited and it's very time consuming to get captions the way I want them, especially if I need to make an edit in the middle of my timeline and now have to move potentially move hundreds of captions one-by-one.
We have completely redesigned the captioning workflow in Premiere Pro version 15.0. You will see this feature as well as many other dramatic workflow improvements. Please update to the latest version.
