My Build and Sony Vegas : What should my expectations be?
on Sep 3, 2016 at 8:58:56 pm

Hello!

I've been making videos in Sony Vegas for years, primarily at the amateur level doing 1080p videos for YouTube.

I've gone through several stages of hardware upgrades, changes, etc, but one thing never made sense to me.

More often than not, throughout these changes, I saw little to no big differences or improvements when upgrading.

So this leads me to my question: what are reasonable expectations for how my hardware SHOULD (if I'm not doing something correctly) be performing, and how to maximize efficiency in render times.

Currently I am running:

Intel Xeon E5-2683 v3 @ 2.00 GHz
Kingston HyperX DDR4 Non-ECC Ram @ 2133 MHz
2 x GTX 780 Ti

All on an X99 MSI Krait SLI Edition mobo.

I often see videos of people with usally lower specs than I rendering 4k footage (let's say, a 3 minute clip) in nearly two minutes on their hardware. I can't think of specific examples as far as components go, but they either match or are below the specs that I currently run.

So that would mean they are rendering in 66% of the length of the video. Cool.

Me? I can hardly render a 1080p clip (1/4 the pixels of the supposed 4k videos) at 30fps in real-time.

Don't get me wrong, that's good - but is there something in my system, or a known combination of components that can achieve aforementioned fraction-of-the-video's-lenght render times in Sony Vegas, or is such a pursuit a lost cause?

I'd be interested in hearing some opinions.

First Vegas Pro will only work with 1 video card so it will only use 1 of your 2 x GTX 780 Ti. Second, Vegas Pro works best with AMD Graphics cards so your choice of NVIDIA is not the best for Vegas Pro. So someone with a Quad Core with an AMD Radeon R9 290x will probably get better performance.

Finally, What format are you rendering to? That makes a big difference. If you are using the MainConcept AVC encoder, it won't work with your GTX 780 Ti at all and so you are encoding just with the CPU's. Vegas Pro will only use 16 threads max and your CPU is only 2.0 GHz so once again 4.0 GHz Quad Core might actually give better CPU Only rendering performance. I find that Vegas Pro doesn't make great use of multiple cores. I have a 12-Core and I have never seen it drive all of the cores hard.

Hi!

Thanks for your response.

I play games as well, so it's for that particular reason I use the 780 Ti's, specifically.

I was previously using Main Concept AVC - I always figured that because GPU acceleration option was available, it would subsequently make use of my GPU. That's interesting to know!

What codecs or presets should I be using to take advantage of one of my 780's? Given I don't plan on trading them in for AMD anytime soon. The CPU does throttle to 2.6 under load and I've seen approximately 70% usage.

I was previously on a Quad Core 4770k, but traded it in for the Xeon to allow for some other multithreaded processes. I still have them, so perhaps I will put them into my other machine and install Vegas there to perform some tests.

Any tips to maximize render efficiency with what I have would be appreciated.

I might even get a dedicated AMD card to slide in between my Nvidia cards for this purpose.

There's really not a whole lot that you can do with those graphics cards. Vegas Pro just doesn't make good use of them. If Vegas Pro is pushing your CPU to 70% that's pretty good (although you did pay for 100% of the CPU) ;-)

Sorry, you not gonna get any faster output from Vegas, as John also pointed out.
Plus to a point, you are already getting decent output speed from Vegas, So.....
