Insanely faster render with Vegas?
on Jul 21, 2014 at 7:36:57 pm

Hallo there!
I have to use Vegas for my work but I need the fastest rendering ever to save time for other works.
Since I'm already using the "right settings" to save time, I decided to upgrade my pc....my old specs were:

Coolermaster Centurion 6+ALI
750w Corsair
CPU quadcore Intel i7-4770-m/b ASUS z87/m plus
SSD 120gb
vga Sapphire HD7750
16gb RAM 1600mhz Corsair DDRIII
Windows 7 home premium 64bit

But then, since i render using the GPU Encode settings, I changed my graphic card with a
Geforce GTX 780 DirectCU II OC

They told me it was one of the best cards out there for what I'm looking for, but
the rendering time didn't changed a bit....so...what shoud I do? What I have to update to have the fastest rendering time ever? I'm kinda lost here....

Please, answer to this dilemma, it's quite important...

Intel Xeon processors will yield the fastest render times.

An example of the rendering times?

With the actual settings (much like these https://www.youtube.com/watch?v=odQiXruP4UY) I can render video 1080p 30fps in....about the same lenght of the edited video plus some minutes (20 mins of the edited video takes about 22-23 mins).
With that processor how much will it take?

As Dave said, only Intel Xeon processors can give you any significantly
faster render times. We don't have a Xeon processor to give you an exact
estimate, But since you seem to be in earnest, that's the sure route.
No GPU card is gonna get you super fast rendering out of Vegas!

I understand... but I'm spending money here, I'd like to have at least a witness of the rendering speed... if anyone knows somebody with such a processor....
Anyone has a suggestion for a good Xeon processor? Is it compatible with my kind of pc, anyway?
Does anything speed up the rendering except the things we just said? How about the RAM?

[Gabriele Marella] "if anyone knows somebody with such a processor...."
I have Dual Xeon's in my 8-core Mac Pro. You might want to perform the render tests that I used in this post: "New" graphics card and see how your computer stacks up.

As stated in my post, these results are from my 2008 Mac Pro 2x2.8 GHz Quad Core Xeon E5462 (8 Cores/8 Threads), 16GB memory, ATI Radeon HD 5870, SSD boot, 2TB HDD Raid 0 (which, btw, I picked up for only $740 on eBay!)

Uhm.... so the test you made takes more or about the same time for the edited video....?
Honestly I was expecting more from that DX.

Well the test are really testing two things. #1 the two video cards but #2 they are testing my dual Xeon's against a single 6-core but because he 6-core is several architectures newer and clocked faster it performs overall faster than the older 8-cores. I'm currently looking a buying a newer 12-core Xeon.

The test also shows that OpenCL performs better than CUDA for timeline playback which is why I concluded that AMD Radeon cards are better than NVIDIA cards for improving playback in Vegas Pro.

Yet, the rendering time is about the same as mine.
Do you think the 12-core would give a better performance for the render rime?
I was aiming for...I don't know....a quarter of the time for video rendered with 1080p 60fps settings.

[Gabriele Marella] "Do you think the 12-core would give a better performance for the render rime?"
If you were rendering using CPU only, then the 12-core would definitely increase performance. if, however, you are using GPU rendering, the 12-core might not perform any better because it will be waiting for the GPU to return the data it has processed so at that point, the GPU becomes the bottleneck in the system.
[Gabriele Marella] "I was aiming for...I don't know....a quarter of the time for video rendered with 1080p 60fps settings."
If you are currently using a 4-core and you move up to a 12-core and you render with CPU only, you should get close to 4x faster or "a quarter of the time" it takes now.

Like I've said before, with GPU rendering, sometimes my GPU is at 40% and my CPU is at 20% and I'm left wondering what is going on and why isn't one of them maxed out to 100%? It's a complete waste of available resources. Same thing for timeline playback; I'll be watching the timeline stutter and neither my CPU or GPU is anywhere close to being 100% utilized. I can't explain it.

John,

The more I research this, the more I am beginning to think that each format is unique. In that, one may perform better with 2 CPU cores than 4 or 6 cores. Another will use all the available cores to deliver the best performance. Still another might take advantage of multiple GPU’s, while still another may only be able to utilize a single GPU core… It seems to boil down to what CODEC's are being used.

Another possible issue is mother board bandwidth. On some boards multiple slots/connections may share bandwidth. There may be a bottleneck in the data flow among CPU, GPU, and drives.

Both are probably true. Some CODECs are a lot easier to process than others and some may be GPU accelerated while others are not so you are correct that formats play a role in performance too.

rather than the super expensive Xeon line you might look into the 4930k or the soon to be released Haswell-E parts on the x99 motherboards.

less expensive with similar horse power. They OC well. I just finished a 3930 6 core build that runs at 3.2 GHZ stock and I OCed it to 4.5 ghz (unlocked multiplier makes it easy) and I am seeing about 30-40% decrease in render times with the same project from my 4 core i7 3770 CPU.

Same GPU, same RAM

David, do you over clock with the software tools provided or do you go into the BIOS and tweak things? I've never over clocked my Core i7-3930K Sandy Bridge-E but Im thinking it's time to get more punch out of it with some gentle OC'ing.

with older CPU and motherboards I did all my overclocking in the bios with extensive stress testing and such.... I started with the Opteron 140 CPU on the Socket 939 :)

but with the newer motherboards the software "auto" overclocking is so good and simple there is not a reason to do it the old way.

but like any short cut it is important to understand the concept behind the shortcut.

I used the "fast" overclock function and not the "extreme"

I am using the Corsair H100i with 4 fans in push/pull configuration for CPU cooling and it does an okay job.... I cant OC as far as the CPU will go because the massive heat dumb the 3930k is...

I am pulling 450w at the wall measured by my UPS (With my LCDs attached as well)


I learned everything I know about OCing at [H]ardforum back in the early 2000's

I remember using a graphite pencil to bridge the laser cut traces on celeron CPUs :)

PM me if you want/need help with OCing

David Thanks. I'm going to start with the software tools as you suggested and monitor things closely.

Thanks again!
