I'm creating multiple short animation videos as an online tutorial for a website. I have 20 created over the past couple weeks. I just reopened some of the beginning ones and it's not showing me the project. It still shows me all the layers in place and all the keyframes in place, but looks like I'm starting a new project in the composition window. Half of my files are like this and half aren't. I really don't know what happened. I'm new to the program, so it could be a simple button push to fix the problem, but I don't know what it is!
No worries! You can't see what's inside the composition because the window you have opened is the layer window. To view the preview for the composition, double click the "Arrows in View" in your project panel. This should fix the issue
