I'm working on creating a basic slideshow so I have pictures animating in and out. There are around 300 pictures and now that i've completed the animation i've started to place masks on them one by one to feather the edges. As I was working my way through the pictures something odd has happened. I can no longer see the layer on the timeline. The layer name is there it appears in the composition window, and you can see the key frames. but i can't see the clip length or move it. Any idea's?
I'm currently running Adobe After Effects CS6 220.127.116.11 on an iMac running OS X 10.9.5
I've attached a screen shot of the layer above that's visible and the ones below that have disappeared.
