Well I wanna make a begining animation for my studio that makes the videos. I'm trying to test it right now but I can't seem to make it long enough to make the animation. Is there any way to extend the composition or just make the plain time line longer?
Composition Settings - Ctrl k - Change Duration.
I usually make it much long enough, and then shrink it later. Once you get a length you want, set the work area (b sets Beginning work area point, n sets eNd WA point), then Composition/Trim Comp to Work Area.
