I am doing frame by frame animation and origonally had my frames set to 1 image for every 4 frames but I want to change it to 1 image for every 8 frames. I know that I can expand it by highlighting a layer and dragging it until the X2 banner comes up, however if I do this to mulitiple layers at once it messes up the the synchronization of the layers since not all the layers start at the same time. Does anyone know how to double the lenght of all the layers at ocne without messing up the synchronization? Thanks!!
