    thanks to all for your help. when i do auto trace it crates only one mask so i can’t move expresion from mask to mask even though i’ll check that cos sounds intersting. moving back to photoshop is something crazy i think, they r image sequences, about 600 images in total, i got it from someone and they were badly cut, there is quite a lot flickering. i’ve tried precomposing but it doesn’t work either, it creates a mask when i do auto trace but can’t modifie the mask. anyway i think i’ll have to go for the traditional method, rotoscoping.

    thank you very much guys.
