I know a lot of people use flash for cartoons and things like that but what about sprite animation? I'm looking for software that will do that kind of animation very smoothly and since I already have a subscription due to After Effects and Premiere, it wouldn't hurt to see if Flash would work too.
Flash is great at character animation, or animating anything really. You don't normally need to use sprite sheets, a Flash animation is a timeline of the individual poses. But, other tools do need sprite sheets, and Flash Pro is a good tool for creating those. Also, when you're doing HTML5 Canvas projects, Flash Pro can be told to use sprite sheets.
