Vegas Editing PC configurations that allows other apps to run effectively while Vegas renders?
I am looking at the following Windows 7 editing PC configuration for working with HD Video:
3.2GHz I7 hex-core system, 24GB Memory, Quadro 4000, SATA 7200RPM 2TB system disk,
7200RPM 1TB scratch disk for rendered data, 7200RPM 1TB disk for system swap/temp
files, ESATA Raid 0 for source video data, external ESATA for backups.However, I’m worried that Sony Vegas 10 renders (particularly for Blue-Ray) will consume the system & I’ll only be able to run other applications “in slow motion” – such as MS Office, Photoshop, and 3D CAD software (Alibre, Rhino).
My questions are:
#1: Is this a valid concern with the I7 configuration mentioned above?
#2: If so, would a dual 2.4GHz quad-core Xeon system avoid this problem?
#3: Would an SSD system disk provide any benefit?
Thank you for your help!

I believe rendering AVCHD video on any computer will cause other high CPU usage programes to slow down.

I only have an aging QuadCore and HD renders don’t consume my system. I’m usually editing in one instance of Vegas Pro while I render in another and email and a web browser up at the same time. Windows 7 is good about multi-tasking and keeping the UI threads very responsive.

More CPU power is always better because rendering is very CPU intensive.

None at all. Disk IO is not the bottleneck… the CPU is.

I record and edit mostly weddings and special events, I’m not big time, but Ive been at it for over 7 years. I recently built my own desktop PC for Sony Vegas Pro 10 and windows 7, 64bit, I currently use an AMD 3.2 ghz 6core processor as well as mid priced ASUS MOBO, with 12 gigs of DDR3 ram, I have 5 hard drives running with one Seagate free agent 5400rpm drive on an external USB 3.0 interface.
Recently, I edited a rendered a music video from a Chicago area wedding band https://www.clarkjohnsonorchestra.com, which had 5 video and audio track layers, dozens of video effects and transitions. All the original video was placed on the external drive and I rendered to one of the internal WD raptors. While rendering (which took a couple hours), I was able to surf the internet, run MS publisher and outlook without running in “slow motion”. Vegas pro 10 seems to really run well with my new 6 core cpu. If you do the xeon cpu’s Im sure you will have no problem with running multiple processes, since I have no problem with it using a $200 AMD chip. I dont know how well AUTO CAD programs will run,since they are pretty intensive. Good Luck!

Try to reduce the maximum number of rendering threads (Options > Preferences > Video) 😉

That’s a pretty grunty system you have there. Sounds like you are looking at the i7 970 CPU. Good choice for video, and one that I am thinking of upgrading to shortly.
On my i7 920 system (see my profile below) I am able to simultaneously render two (HDV to DVD) 2-pass variable bit rate projects (90 minutes each), before the system becomes noticeably sluggish. In terms of render times, it makes little difference whether I am rendering just the single project or both at once. I render both projects to PAL DVD WS in about 2 hours.
It’s been a while since I did Blu-ray, but I think the render times were pushed out only another 30 minutes or so. I found the greatest slow down occurs when there is a lot of colour correction, titles, transitions and effects applied.
You might want to consider adding an Nvidia GT580 video card as Vegas takes advantage of the 512 CUDA cores. That’s also on my shopping list for June!
You might also want to check out the Intel Generation 2 i7 2600K CPU’s, but that means using an LGA 1155 motherboard. They have Integrated graphics, which when combined with an Nvidia card, banish the preview lags (or until Sony releases another AVCHD format :-)).The current i7 series uses an LGA 1366 motherboard, so you will need to decide up front what you want.
Having an SSD will improve your system boot and program load time times.
Intel i7 920, 12GB RAM, ASUS P6T, Vegas Pro 10 (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6
