I've recently become a fan of Adventure Time (I know, I'm a bit late to the party) and as an aspiring animator I'm curious if anyone knows what animation software and/or process is used on the show. Now I realize, the software itself has little to no true affect on the quality of the show, as some of the best animation pieces have been made with nothing more than a pencil, some paper and a cheap camera, but I still would like to know for personal reasons.
The show looks super smooth, but not in an Adobe Flash sort of way. It definitely has a more traditional animation feel to it. I've also seen it mentioned in several documentaries and interviews that Cartoon Network works with Wacom Cintiqs which makes me think that a lot of the show is done digitally, but all of the storyboards and things I've seen on forum posts and the Adventure Time Wiki show hand-drawn storyboards. This makes me think that the show is at least initially drawn on paper (especially with Rough Draft Studios Korea working on it) and perhaps cleaned up and colored digitally. If that's the case, then I'd assume they are using Toon Boom Harmony or some variation of it as it is one of the most popular software packages in the animation industry, but I couldn't find any proof of this online via Google searches and such.
If anyone has any idea of these things, I'd love to know =). The show is so beautiful and inspiring and I'd love to have more inside information on how it's made ^_^. Thanks for your responses in advance!
PS: I tried to ask Pendleton Ward on Twitter but haven't had any luck yet...he's a busy guy after all.
