issues with Twixtor -
 

hi guys
I downloaded the demo, and started using it...
I have to say I am a bit confused....

it's sooooo processor intensive! I use Vegas pro 10 and shoot 25p with a Canon 5D mk2.
now...I now 25p it's not a good starting point, but regardless of that, if I try to put quality "good" or "best" it seems to take an absolutely eternity to render...
I also have issues to preview, even at the quarter setting
my computer is fairly powerful
ntel® Core™ i7-720QM Processor with 2.8GHz
8GB DDR3 SDRAM ( 2x4GB)

I have tried working with lower quality videos, or outputting to DVD quality, and it kind of works, but if I want to output to AVC 1080 it seems to take like hours

other question: when I use Twixtor and decide to slow down to, say, 30%, I then need to stretch the original length of the clip or I loose 2/3 of it (in this case): how do I know exactly how much to stretch the clip to, for this to be precise?
