Video Rendering not using 100% CPU

post #1 of 3
Thread Starter 
ive used sony vegas 9, 10 and 11 aswell as adobe premiere pro cs5 and rendered in different formats and settings and all of them only use 6-13 cores and only 25% cpu power and its not setup to use graphics to render. how can i use all 24 cores at 100%?
I should game.

Bottlenecks including RAM and HDD may be taking over when doing things such as processing effects and video/audio layers.  Rendering a file from Vegas is not like simply transcoding a file into another format.  There are other things Sony Vegas has to process so things wait for each other naturally - it's not always straightforward.  Same goes for Premiere.

 

Consider placing all your project video files on one HDD and when rendering, write to the other HDD.  When reading to one drive and writing to another, the process is sped up because HDD to processor throughput is maximized.  I do this a lot.  For small projects I use my X-25M SSD as the 'read buffer' since the SSD is much faster for reads.  You can resave a project and all it's media files by clicking "Save as" -> and checking "Save media with project" in the dialogue.  Be sure to create a new folder.  Any related media saves in that folder which when appropriately positioned should be in that HDD you want to read from.  Render the project file to the other HDD.  With Western Digital 1TB Black HDDs the process should be fast.

 

Because video files are often stored, moved around, copied, read and written in memory during the render process, ensuring additional bandwidth with a fast memory setup with high speed (low latency also helps on AMD systems) certainly helps with the process.

 

Cheers; an experienced Vegas user

thanks for the answer i tried it again reading and writing to the same drive with these speeds

393

in my render setting i can choose render cpu only or gpu only i have mine set to cpu only
i have 12gb of ram at 1760mhz stable with 9-9-9-24 timings
cpus clocked at 176 x 16 and it turbos to x17 to give me approx 3ghz
heres a image of what happened when i rendered with all of the above

337

more cores are being used this time but not fully
I should game.
