I have a project that was initially developed for ipad retina, that I'm now reworking as a standard 16:9 screen project. I've pasted the retina sized project into a 16:9 project, and the clips are a bit too large. I want to scale them down uniformly by about 30%, but the challenge is that they're not all scaled to the same percentage. When I nest them and try to rescale the nest, it clips off everything beyond the initially visible screen area. Is there a way I can resize a group of clips in another way?
Click in a bin and make a new adjustment layer. Paste it on top level of a new sequence that contains all of your other sequences (not nested).
Apply video effect/distort/transform. The scaling it will affect everything.
