The easy answer is, since one viewable image is carried on one set of scan
lines, and another viewable image is carried on the other set, and, since
the two sets composite into a standard 2-D flattie, you wouldn't be any more
likely to get flicker than you'd normally expect to find on the trailing
edge of some moving object. 

The real world answer is, in the early days of my video SL3D, I was getting
some flicker. It would be noticeable where I had allot of contrast, like
with lens flare. I think I corrected those problems by improving the sync.
Kind a like you may see with titles on the "big screen", where the shutter
and pull-down are a little off and you get smear. But, I've also been
running at 120 Hz for quite awhile now.

I think Paul Talbot has a good idea for this question.

previously)... 

Some on this list have done allot with anaglyph SL3D. Paul Kline sent me
some of his jpeg's awhile back. I believe I have his permission to show
them. I can only demo video.
