Wow...I have a 9min sequence of 720p P2 clips..click the sequence from the bin, then File->Send to Speedgrade...takes nearly 15-20minutes!!! LOL! SERIOUSLY! And WHY did you (Adobe) send AUDIO to a color grading application???? Why introduce the overhead??? I don't need to hear anything while i'm grading!! Colorist typically don't!! I'm assuming that .DPX transformation is simply too expensive a process...and your tutorial videos showing this to be some speedy process is complete bull. My system specs:
Win 7 64bit
16GB mem
3TB drive (dedicated to editing, NOT operating system drive)
AMD Phenom x6 1100T
