Stephen,

I suspect things like drive speed writing and reading, codec speed to write e=
ach frame, and other bottlenecks can change the speed and efficiency of HT.=20=


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 wa=
iting on those frames to be brought in before the rest of the rendering can t=
ake place.  200 cores or threads wouldn't make as much difference if AE stil=
l needs to pull each frame and it takes a while to do.=20

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 p=
lay together.=20
