the power of the mercury engine

I don't think the Mercury Engine has anything to do with rendering. It simply allows real time preview without rendering provided that your file matches the sequence.

Does the Mercury Engine in CS5 speed operations in all file renderings or just AVCHD?
Click to expand...

An Adobe engineer at NAB2010 told me that Premiere Pro's pipeline goes something like this:


File read ---> File is converted to RGB ---> scaled and rendered to screen --> Frame is served to encoder --> Encoder crunches it.


The Mercury engine accelerates the RGB conversion, scaled rendered to screen and served to encoder. While it doesn't accelerate the part where it gets crunched into h.264 or WMV, it does speed up your final encode since the GPU can do all three steps in parallel. It frees up more CPU for you to crunch those frames faster.

Mercury engine speeds up just about every aspect of your workflow except your DISK I/O and the actual crunching of the frame. But you will have more CPU to crunch frames so even that part should be faster (even if CUDA doesn't do the crunching)
 
Gotta say... Shot a press conference today, had to send 18 mins of raw footage to my client. Started with 720p60 off my HMC-150 , time line for titles, export to Mpeg4 700x400 3000kbps 1 pass, it's as fast as real-time.. which a few weeks ago before I got my GTX460 would have been easy twice as long, maybe more. Pretty sure the GPU is playing a part in that.
 
It is speeding it up...If you go to the Nvidia set -up window and set up applications for the Cuda cores and select all apps that benefit and have code for it .

I shot material in 720p 60p AVCHD (Hacked GH1) edited quickly and outputted to 1080 24p highest quality possible Mpeg2 13 min vid took 18 min . looks fabulous and no errors .this is very fast compared to MPE software only ...I am using nvidia 460GTX
