January 29, 2011 at 7:21 pm in reply to: Sony Vegas 10 Slow rendering CPU / GPU rending testedInteresting read…
Things I have noticed:
I switched to Nvidia cards mainly for Premeire Pro CS5. I didn’t bother with the Vegas 10 lateral grade. I still use Vegas 9 on many projects though, fast and simple can not be beat by Vegas! However, I went from Dual ATI 5750 to the GTX460 and a GT 210. My previews or not nearly as smooth as they used to be. The 460 is used for preview and primary screen editing. The 210 is used soly for a file managment, internet monitor.
Using a multiple SSD’s for assets and Rendering made no difference in rendering speeds, still averages the same as a single HD or a Large RAID with 2gig cache. Although: I noticed that just after a few months All this rendering and asset managment KILLED, I repeat KILLED the SSD’s. Nand Flash is not a consumer product, Xerox needs to sell them, they are only good as prity paper weights.
Other things I’ve noticed:
Vegas Takes lirterally 3x longer to render audio than Adobe products, audition/soundbooth/PPro. Of course all the settings are slightly diferent and I’m no audio engineer with super sweet hearing. But it sounds the same to me.
This leads me to think part of the Vegas rendering issue is dealing with sound bits.
I just like speed and a good looking finnished product. I find it harder to keep my editors on the same page using the same codecs and redering to proper outputs on a consistant basis more challanging than any issue with any NLE for that matter.
Trying to apply a science to this edditing stuff is more akin to the acult for amazing output that some people get!
Have a good day…

January 28, 2011 at 4:12 pm in reply to: Sony Vegas 10 Slow rendering CPU / GPU rending testedUpon my testing, I now have the GTX 460 in one computer and GTX 450 in another. I think the GPU processing is working just fine. It’s that there isn’t that much for it to do. The majority of processing must be done with in the CPU. Even Premeire Pro CS5 with MPE engaged, I only see about 10% speed improvment when rendering. The MPE is realy for timeline scrubbing, and that is really important to me. I need to see my results with out prerendering all the time.
Sales Gimiks and Hype to boost sales! What are we poor foolish consumers to do, but fall for it every time.
Has anyone done a visual comparison from GPU accelerated vs all CPU? I mean really blow it up on a projector? I would love to see if the gpu keeps the same quaility of the software. Thats where Vegas used to shine beyond all, visual quality.

That is odd.
Try making sure your project setting are really set for your desired output. Then when rendering check the box on the settings – use preject settings.
Dont check any of the other boxes…give it a run

Interesting read. I have done mucho testing… Vegas seems to like a quad core over the 6 core. Clock for clock my AMD phenim II is the same speed as my 980x, that is my AMD is 30% less on the ghz and 30% slower and the renders… Therefore Vegas uses very simple float point calculations. I’ve found that Hyper threads are more like little anchors in Vegas Pro. I actually loose about 2-5% performance.
I have also tested many HD config, raid, ram drive etc. The compression of just about any high end codec limits the HD access to about 15 megs a second. Low bit rate like AVC at 512k is about 80megs a second. Therefore you really only need a solid 7200 RPM Sata HD, for all your needs.
I can only tap out my HD’s (raid 5) running in UNCOMPRESSED at an astounding 575 megs a second for a render. My raid will push just under 800 megs a second, so reading and writing seems to be at it’s peak.
To test that, I’d need to set up my ram drive again and render to the HD’s only with out the source files attached. But then again, I don’t use uncompressed, even at 12TB’s of storage, too much space wasted…
I hope the Buldozers are cool, then I’ll see if 16core – Vegas Max supported cores makes a dif.
This tuesday, I get to test an 8 (16t) core Xeon system…
take it easy…

There isn’t too much you can do… I played with the S-curves, you can get more but with out the orginal footage a good test is tough.
You can try this HDR trick, I love the looks I get from it!

Good luck

can you post some rendering times for encodeing Sony AVC codec, and cineform if you have it…
Thanks…
I have done extensive testing with HD, RAM Drives, Intel v. AMD…
I found unless you’re running Uncompressed video, HD speeds mean nothing…
Clock for Clock, AMD is the Same as Intel, quad core seems to be the most efficient.
Good luck

Depends what you are trying to do. Cinematic quality, neither doo well, but the ex-1 has far better image quality.
1: Ex-1 – 2hr battery life…
48minute record time on supplied dual 8gig cards…ships with one, I got free one when regitering cam.
excelent low light… .14 lux
Needs laptop with express port to offload SxS cards quickly or
slow usb2.02: NX5
2hr or so battery life
hours of recording with cheap easy hdsd cards 32gig = cheap…
poor light sensitivity 1.5 luxI vote Sony Ex-1r for better quality image, light, and just carry a laptop…
EX-1 is also HDTV qualified…

This happens to me sometimes too… I just have to restart vegas when the vid disapears…

Cineform is at : https://www.cineform.com
Open up your file manager to the directory to the location of your media that you are droping onto the time line. when you drag a clip to the vegas timeline a file is created with the same name with a sfk file extension.
media.avi = your vid.
media.avi.sfk = proxied file for vegasI highly doubt thats your problem though, it was most likely your QT program, new versions don’t work as well as the older ones… search the forum, people discuss that elsewhere…
good luck…

I don’t think it’s possible to put anything less than one frame… I mean think about it. All video, film, picture flip book…. It’s all frame by frame, no magical way around it….
Before you get all hoity toity, of course there are ways with dual streams, but once placed on a sigle rendered track you are limeted to the frame rate andrefreshrate of the display…
This could be an interesting experiment with those 120hz tv’s but then again it’s still just 1 frame at a time.
Also, the human eye has a 30hz refresh rate too, so to fast, and even though it’s there, you can’t preceive it…
