after effects not importing all selected images
I'm making a stop-motion animation in After Effects. On a new Macbook air. I am attempting to import 500+ images, png files, they are numbered in order with appropriate zeros. I select all 567 images and import. Then make a composition and load them into the composition and sequence layers. I see only 480 or so have imported. I start over and sometimes i get all 567, sometimes I get another random number. But it's not consistent. There is never any error message and I don't know anything is wrong until I see the animation is choppy and realize it's skipped importing some images. Any ideas why After Effects is skipping random files when importing? Thanks!
