My opinion about Vegas Movie Studio 11 and Vegas Pro 12 is that they are not very stable. In order to get the final render without hanging or glitch problems in 3D you have to be cautious. My experience is that I should not work with external disks and GPU acceleration should be switched off. Moreover, the footage should not be in separate (left and right) files, but, preferably, in left-right configuration. Moreover Sony Vegas does not like xvid avi files (glitches and other problems are more frequent when using such files). I still have not found video codec which would run fluidly in Sony Vegas (non-pro and pro) for files in left-right configuration.
On the other hand, Edius (6.5) runs smoothly.
However, Edius auto-3D-align option (rectify) is not accurate and cannot be compared with Vegas auto alignment option which is very accurate.
Moreover, after aligning the files, Edius output is not as sharp as Sony's one. Go figure.
The results of auto aligning are attached below (see left-bottom part of the picture produced by Edius).
The relatively bad auto-align of Edius and slightly more blur video is a no-go for me, so I am still using Vegas (both versions). If only Vegas is more stable and fluid... :-(
