Ok, I have watched videos, read the help but cannot seem to get to stage one of learning Roto Brush. I started a project, imported one video in one comp and that is all there is in the project. highlite the comp window, click on the roto brush and go over to the video to work. All the video's show the cursor changing to let you know the roto brush is activated and ready to go but mine is just the cursor and if I click to draw it thinks I want the video and just grabs it and moves it around. What on earth am I doing wrong here? After Effects CC, all up to date.
Ok, just found a new cloud update and rebooted....suddenly its working.
