i dont' unerdstand how to use layer masks in premiere, like, in some tutorilas, they say mask this out, and put a mask on this inorder to see through that, blablabla. can someone explain to me how to use masks in premiere? also, can u tell me how to use it in after effects? thnx alot!!!

Pages 256 to 261 of your Premiere Pro manual cover this more than adequately I thought.

Which parts, specifically, did you not understand?

As for After Effects. I would get the hang of the simple way of doing things in Premiere first. Explaining how to mask in After Effects would take more leisure time than I have this month.

Edit: a couple of typos to make the post look more 'English'!"
