Hello, I have an interesting issue that I'm hoping someone can shed some light on. First, my system specs.
Intel Core i7-3930k six core (no overclocking yet, just Turbo Boost as I just finished this build a couple days ago).
16GB RAM (1600Mhz, CS8)
256GB Sata III SSD for AE Project files, AE disk cache, and source files (two 1080i videos on this project)
128GB Sata II SSD for OS and Programs (no games, just AE, PrePro, and MS Office)
500GB Sata II HDD for effect files (explosions, smoke, sound FX, etc. But none of these are used for this project)
Nvidia GeForce GTX 460 SE (1GB VRAM)
Windows 7 64 bit
AE CS5.5
The clip I'm rendering is 10 seconds long and has two layers of 1080i AVCHD videos, 1 layer of rotoscoping for the full 10 seconds, color finesse, keylight, some basic static masks, and I'm exporting to H.264 bluray on my C drive with the Sata II SSD that has just program files and the OS.
Now the issue. My issue is that none of my hardware is maxing out. The CPU bounces around between 50% and 73%, my disk cache and source file Sata III SSD is only transferring at about 10 to 20MB/s (capable of sustained 520MB/s reads and about 505MB/s writes), my Sata II SSD where I'm exporting to is bouncing around at only 2 to 5MB/s, only about 6 of the 12GB of RAM I have reserved for AE multiprocessing is being used, and my video card usage is bouncing around between 40 and 70%. I don't know what else to check. My SSDs are hardly being used and everything else is only reaching about 70% of it's capability.
Does anyone have any idea on how to determine where my actual bottleneck is coming from?
I saw a couple posts from years ago on this, but one ended up being a video card bottleneck and the other was resolved by just changing the output format (likely another video card issue). In my case, the video card's MAX usage for the duration of the render is maybe 72%.
And not that this information is very helpful, but the render time is about 11 to 12 minutes to finish the 10 second clip... It might be useful to know that just loading the 10 second clip fully into RAM for a RAM preview only takes a couple minutes at full res., maybe 3 minutes max.
Thanks in advance for the help!
