Hey man, INCEDENTALLY, I just found out a way of making movies run at a way smoother framerate.
Let's say you've got alot of big movieclips: Paste them into a new document, export them as individual .PNG images (because PNG supports transparency) and then import those images back into your movie. If you find the image in the Library, Right-Click on it and go to Properties. From here you can drastically decrease the filesize and make it alot easier for Flash to load.
See, Flash works in vectors, so every frame it has to work out a load of crazy co-ordinates (As you might allready know) and then, in your case, apply filters to them. If you use an imported image though, it's loaded on frame one, and that's it. I JUST started doing this though, so don't hold me to it. I suggest you try it on that background though, assuming it's not animated.
HOPE I KELPED.

Looks nice :) I liked Future alot. Great movie.
But what you could do is instead of using Filters, you can use the filter, take a screenshot then replace the original vector art with filters with the new screenshot :D That way it'll look the same, AND it won't lag :D Although it'll look a little 'pixely' but I think its worth it.. Specially if there's going to be a LOT of filters

That's a good idea, in theory, but there's two problems:
1. If I did that, I wouldn't be able to animate any of the backgrounds, so I could only do it to static objects, which there are very few of in this cartoon.
2. The file size would probably get ridiculously huge, a typical JPEG image being about 78 KB's or so. Multiply that by a huge amount of backgrounds and objects with filters, and you're getting a big cartoon.
Thanks for commenting though, I hope you'll check out the cartoon when it's done!
