You can control resolution, pixel shape, frames per second, and interlacing when you're preparing to render your animation. Individual animated frames look as good as stills, although the highest qualities do make for long renders. You can also enable motion blurring, although I'm not sure if its quality is up to broadcast standards. I would think that like any other 3D package, the quality of the final output would depend on how Vue interacts with your codecs and hardware, and I haven't done a lot of trial and error in that department. If you have to compress heavily because of memory limitations or other hardware constraints, any package's output will degrade.
