Maximize Intel Core i7 Power

So I decide to install sony vegas 9 pro 64bit and render a 25 mins project with sony color curve and soft contrast effects.

I split the project into 4 regions

I open up 4 Sony Vegas pro 9 x64

I start render each region with each of the opened sony vegas to MXF XDCAM 422 50 mbps

WOWWWWWWWWW, their using all my cpu power, i never seen this happens before

BTW: project information: xdcam ex 1920 x 1080, 35 mbps 23.976, Best Quality 32BIT FLOATING VIDEO LEVEL!!!!

wow this is amazing... sony vegas is the best and sony mxf hd 422 is way better than cineform. I tried cineform but all messed up, freeze and crash

discuss!!!

nothing to discuss - agree entirely ;-)

Frankly, I don't quite get the idea behind splitting a 25 mins project into four segments.

Using my QX6700, I'm also getting 100% CPU usage rendering EX HQ projects over an hour long, in a single instance of V8 or V9...

well the new i7 has 8 cores, so when i render in single instance of sony vegas, it only uses 50% of my cpu. I think sony vegas only uses 4 cores.

so by opening more than one sony vegas, can i put my core i7 to its fullest.

i never had a quadcore cpu before

Fair enough; I never used Vegas on 8 cores :)

On 4 cores, Vegas has been able to run 100% ever since I used it for the first time, ie. V7.

How much faster does it render the four parts versus rendering the entire thing at once. Also, how long does it take when the actors have their clothes on?

I'm surprised you need to split it into 4 sections to use 100%CPU too - I can get to 100 on my Q6700 too with a single render - Seems Vegas should use all of your cores regardless unless there's another bottleneck - but I can't imagine what bottle neck would not apply to splitting projects up vs running as a single project.

it does look like you are losing a part of your image though, I would think those white dots all over will detract from the finished project.

I'm curious about this. A core I7 only really has 4 cores. The other 4 are HyperThreading, which means to me that the Core I7 is just very good at dividing your 4 cores in half to make logical cores.

Have you done speed tests to see what the difference is?

Your Q6700 doesn't do HyperThreading. HyperThreading will often make it appear as if your cores are running at 50%. I'm unclear about whether this is actually what's happening in reality though and I think a speed test would be more telling than a meter that reads 100%

Did you try changing your thread count in Vegas to 8? In Preferences

Ive never done a test but this is how it goes:

single instance of 8bit project with sony color curve + magic bullet look 2 hours; cpu useage = 50~60%, I can still do another editing or after effect works.

multi instance of 32bit project with sony color curve + sony soft contrast 1 hour 45 mins, cpu useage 100%, computer is running really slow on other application.

its so fast to me...

----------------
@ John Cline: only 5 mins :)

@ Srode: The new core i7 seems doesnt like to use all his power for some reason, maybe intel want this one to be a multi task processor, i dont know. like i said im very bad with IT

and the white dots are my attempt to keep the only sony vegas community clean.

@ Disneydude: I ve it before but it doesnt change anything

Gotta love sony vegas!
