Didn't the first person to run a marathon die afterwards?

Here's a short cycle that I made to test a potential workflow using Flash for an upcoming project. All of the animation was done (slowly) on paper, then scanned and imported into Flash. Cleanup, ink & paint were all handled in Flash.

It's been a while since I last animated with the old paper and lightbox method, and the going was pretty rough. I kept looking around for some magic 'cmd+z' keys to whisk my mistakes away. And you never have to deal with greasy erasers on a wacom. I guess I'm just not old-school in this regard.

Based on the way that the video breaks up when exporting from Flash, I don't think it's the way to go. I've exported this video a number of times and the glitches always appear at some point.

*Update - the blank background of the original video bothered me enough to make me revisit this video and give it some groovy speedlines.
