| Stephen, I suspect things like drive speed writing and reading, codec speed to write each frame, and other bottlenecks can change the speed and efficiency of HT. If there's footage being used, HT could see lesser productivity vs non HT if the bottleneck is how fast AE can bring in each frame anyway. You end up waiting on those frames to be brought in before the rest of the rendering can take place. 200 cores or threads wouldn't make as much difference if AE still needs to pull each frame and it takes a while to do. I seem like I'm in the know. I'm pretty sure of the things I'm talking about, but I could be proven wrong. I'm not a complete expert on how HTT and AE play together. ////Greg Balint ///Art Director / Motion Graphics Designer delRAZOR.com/ On Jun 12, 2012, at 9:24 PM, "Stephen van Vuuren" <stephen@sv2studios.com> wrote: > I do know AE does not always handle lots of threads well - but is Adobe > saying it's HTT to blame or overall MP management.
