I'm working in a 1080 24p Aspect HD time line within CS3 (with latest update) with windows XP pro sp2. The project is about 5 minutes in length with about 300 clips and transitions, all of which have at least 3 layers of color correcting effects. I have rendered the time line. Which was a feat in itself, and am now attempting to export the entire sequence to a cineform avi. I am only getting 50% on my CPU usage, which is also what i got when i was rendering the timeline. When I originally installed PPCS3 I whenever I rendered whether it be on the timeline or within adobe media encoder it was utilizing full system resources, now its taking twice the time, appr. 5 hours and rising. please advise.

Thank You.

P.S. I am now attempting to export 30 seconds and it is estimating 2 hours. Should I attempt to Create a DVD Directly from the timeline instead? I do not trust adobe's downconverting abilities. Deadline for project is Tuesday morning.

Certain individual clip effects may not be optimized for Multithreaded rendering, so if you have more than one CPU visible to the OS, that will result in the 50% usage cap. The same thing happens in AE with a very few select effects.
