Having just nabbed Flash CS3, I've (finally) been able to learn how to write flash vids. Now, knowing I't the noob here, I know I won't be able to make anything terribly great for a while. Though, having used GIMP 2.2 for a long while (and realizing that animated .gifs don't work as well for vids) I know some things on drawing. It's just going to take a bit of work to learn the program and which methods to use when creating the files.
IMO, I think I'll go fbf with onion skinning rather than tweening. And the hardest chanlenge I think I'll come across in all this is finding the time to write :P Other than that, it will learning how to write flash to the degree that people expect.
Keep it REaL,
