I am learning how to use the puppet tool and when I try to start animating my subject by holding down controle and clicking on the puppet pins I get this message: "After Effects error: could not allocate sound memory." It is very frustrating and I don't know how to fix it! Can anybody help me please?
We'll have an easier time helping you if you tell us details of your software and computer, including exact version numbers of After Effects and operating system, amount of RAM installed, and type(s) of source footage.
Turn off the sound on your layer(s) while motion sketching by toggling the layers audio switch (speaker symbol). Beyond that more info is required about your hardware and what settings you use in AE.
