I know this question is old but I’m having the same problem as the original poster. The ripple trim tool works perfectly to add 20 frames to the end of every clip but when I try to add to the beginning of every clip, it deselects all the clips and just adds to the one I’ve actually selected. Any solution? It would be great if it were possible in the same way you can add to the beginning of multiple clips when they are on different tracks.
