Andrew,
I'm just going in here because I see your post has been hanging for a while.
Why don't you try the 2D production, .MOV and .MPEG4 and see what
happens. These are QT, and given some people having had severe problems
in PD9 with these formats, your post caught my eye.
When it comes to the real 3D editing and production, I will not be one who
goes in to that for at least 5 years from now (as I would have to spend a lot
of money buying all kinds of stuff and wondering what I would gain) -
but from what I have read so far, I understand that 60fps is the way to go.
I have never even tried to produce these formats you want in 60fps.
I havn't seen the dxdiag of your computer. If somebody else has, they might
tell you more- both regarding the formats, and if your computer has the power.
Just something.
