Choppy / Blurry tweens

[FromChris]

Any tween, in preview or export (quicktime or others) comes out super choppy/blurry... I assume I have some random setting incorrect somewhere?

It's not letting me attach the .fla, to this message, so here's a dropbox link instead.

you're moving an object more than 2000 pixels in less than 3 seconds > 20 pixels per 1/24 second.  that's not going to appear to be smooth to anyone's eye when using a sharply defined object.

ie, use a blur filter or move at a rate that does not appear pixelated.

p.s. this is not a "performance" problem.  if it were, it can help, to use whole number pixel postions whole number object dimensions and especially enabling the objects cacheAsBitmap property.
