You could try purging memory and disk cache before you render. That should help a tiny bit.
Clean your media database and cache.
Is your disk cache set to the SSD drive?
Is your footage stored on the SSD or another fast HDD?
Footage stored on slower/external drives or card readers will hurt performance.
Best performance requires separate drives for program / footage / cache. But I use my internal raid10 array for both footage and cache without too much impact on performance.
e.g. On my windows 7 system: Program on C:, Footage on H:, Cache on H: (raid 10)
Check your preferences for GPU acceleration.
Here are my settings... (click for larger image) (check my profile for system specs)
and the GPU information button reveals...
Hope it helps.
Hi, thank you for you answer
Yes, i do purging the memory before i start render, my disk cache is set to ssd (plextor 256 GB wich heading to some 700mb/s read and 650 mb/s write), and all the footages are on SSD, so i work only on SSD
The settings are in most part like yours. Meanwhile i resolved a problem... my only problem for now is that when i render something, my CPU is not using more than 15-20% The Format is QuickTime and codec PNG..
In fact, wait...i've made right now a test...
if i am rendering on QuickTime with PNG, my CPU is using only 15%... and from a footage (without anything added, effects or nothing)... of one hour and 30 minutes... it will finish the rendering in 7 hours
if i am rendering on QuickTime with H.264... my CPU is using 70%... and the same footage of 1:30 time... will render in 20 minutes
so... How can i make something to render with 100% using CPU on every codec ? that is my problem now
Thank you in advance again!
Hmmm. I just did a bunch of tests, too. Source file = 240 frame QuickTime, no effects, 1920x1080, 24P, animation codec.
- The QT PNG is definitely a memory hog when rendering. My CPU runs @ 14% and memory usage climbs from 8GB to 22 GB while rendering a 10 second video in 4 1/2 minutes.
- Sending the simple comp to Adobe Media Encoder tasks the CPU at 14%, but memory usage maximizes at 13GB and the render is done in 3 minutes. If you have a long clip to render the machine is probably choking on memory.
- Rendering an uncompressed PNG sequence (240 frames) takes just under 4 minutes. CPU @ 14%, memory usage 21 GB.
- AE Renders a QT Animation codec in 43 seconds. Taking that QT Anim file into QuickTime and rendering a QT PNG (in QT) CPU runs at 14% again, and the file is done in 4 minutes with hardly any memory usage.
In all of these scenarios the Quadro K4200 GPU is running at a cool 5 to 10%. My conclusion: The PNG codec is just a poor performer, and your system is set up and running just fine. Others may have different ideas.
Oh, and there can be many factors why the CPU is not fully utilized. In general, data is just not being fed to the processor quickly enough to utilize all of the available cycles.
And I ran one more test, removing the "render multiple frames simultaneously". QT PNG, 13% CPU, very mild memory usage, 3 1/2 minutes.
yes, i saw that are a few codecs that are poor performers too bad because i think that Animation and PNG are the most lossless codecs, that why i use them, and after that i prefer to compress with HandBrake with some advanced options to make the file small and have the "same" quality
I've done the same tests on other computer and is the same s**t soo... not the computer is the problem, the codec has something, too bad that some codecs don't know how to manage the complete resources.. is like you will spend a lot of money... and than you see that you could have the same results even with a poor computer ... in theoretical
