@00:10Flash was decent enough before broadcast went HD, then Adobe bought Macromedia and suddenly Flash started to develop herpes. I'm a solid ToonBOOM whore now. I should be.. I helped MAKE the damn thing.. ^_~
@00:10I don't use flash... well i did once in school about a few months back and i found it so complicated to use that i vowed i'll never use it again 8I (i don't do any animations really anyways unless i'm bored i do very crappy ones 8I)
Large files, typically, especially if there are a lot of layers and bitmaps. If you can at all help it, it's better to store scenes in separate files and edit the video together after. If all scenes MUST be in one file, I suggest having each cut be its own "graphic" symbol.
