Working with Full HD Videos (1080p)

[AcquavivaFS]

heey, i just got a new camcorder, its pretty damn sick, films up to 1080p Full HD, well, the problem i found was that the 1080p takes up a HUGE ammount of space and takes 4ever to render, soi filmed in 720p at 60 frames ps and it looked awesome when playing it back on my HD tv and pc, but when i rendered the video in sony vegas movie studio HD 10 it got all messed up, like the edges of me and the ball get this kind of stripes effect when i move, and it looks pretty bad, so, whats the best way to work with/render/save HD videos??

here is the vid i mentioned (its A CAMERA TEST! not a FS vid so dont start hating.... )

make sure you render your videos at progressiv scan, and not interlaced, and set the bitrate to about 10

2:51 second camera 'test'. 
I would've gone with 10seconds tops.
