I m trying to fade in and out a few different photos. Example,
layer 1 has photo 1 frames 1- 30 with keyframes on 15 and 30. alpha 0% on frames 1 and 30
layer 2 has photo 2 frames 31-60. with keyframes on 30 and 45. alpha 0%. on frames 30 and 60 etc. etc.
but everytime I start at frame 30 in layer 2 it fills in frames 1 -30 UGH!!! For some reason I can pick up where I left off in layer 2 on frame 31 w/o it starting in frame 1. what am I doing wrong here? all i do is click in frame 31 and add the next symbol/photo but everytime it grays out frames 1-30 and puts a black solid dot in frame 1. UGH!!
You need to put a keyframe at the frame you want contents to start.
So, in your example, layer 2 would be blank, and you would add a keyframe at frame 30, then add the contents in at frame 30.
Frame 1 is a keyframe by default. The filled dot represents a keyframe with contents. All "greyed out" frames are a continuation of a keyframe (a keyframe being displayed for many frames)
