jagged edges around shape

[sparrow01]

Hi,
I am animating a box and have used swift's preset box shape and have wrapped a texture on each side. When I animate it edges of the box look jagged when at an angle. Is there some sort of anti-aliasing function to smooth out the edges? I have exported using .png, .avi, .swf and it makes no difference. I have the quality and anti-alias set to max in preview.

Here is a screenshot of my animation:

.PNG will give you the best quality. If that is still unacceptable then probably the only thing you can do would be to clean up each image in Photoshop.
