first, i really not good at use English, so please understand me.
i'm working at roto brush tool in AE.
i'm making animation, so use scanned jpg files. and these files just reduce size in Photoshop.
when i use roto brush, the message(error code) about
'After Effects error: Checkout ID must be non-negative(78::7)'.
how can i solve this problem? please help me.
i'm using MAC OS 10.8.5 and AE CS6.
Don't use the Rotobrush for those. Use Photoshop's tools to cut them out. Photoshop has an edge finder and matte refinement tools that are similar to the Roto Brush, but are made more for working with still images.
i'm really thank you for your advice!
now, i can make my animation for graduation!
