Vegas 11.0 poor preview speed

zstevek wrote on 5/24/2012, 7:06 PM

Hello,

I upgraded to Vegas 11 for the alleged preview speed improvement and it is simply terrible on my machine. I have an NVidia Geforce GTX 465 (latest drivers) which is supposedly compatible with this program.

Has anyone else seen poor performance with a NVidia Card?

Thanks

Post your System Specs in your account profile so others can analyze the rest of your hardware to see if your system is up to requirement...it would greatly help.

I believe the GTX 465 is too old a card. I have a GTX 580 and have very good playback speed. Depending on the amount of work that has to be done on the images, there can be some dropped frames. But overall, I get great playback speeds.

What kind of media are you previewing?
Did you match project properties to your input clips?

Well, I just read this on the SCS Req Specs page.

"GeForce GTX 4xx Series or higher (or GeForce GT 2xx Series or higher with driver 285.62 or later"

I copied this from the SCS GPU Accel specs. So that confirms our chum has the correct Graphics Board.

Maybe it is the driver needing updating?

I'm running a GTX 460 SE at work and a 550ti at home and both cards greatly improve timeline performance in Vegas 11.

what CPU do you have?

What type of media do you have on the timeline? Vegas will only accelerate previews for certain media formats. Vegas will also use GPU acceleration on the timeline for certain filters.

I have a quad core Q9400, 8GB of ram a nvidia GeForce gtx 465 and am running win 7 64bit. Latest drivers installed.

I am noticing a normal preview speed the first 5-10 sec and then it slows way down. I am doing a multi camera edit (3 cameras in preview)

I have done this same kind of edit before with no significant issue like I am having right now.

I think the power of the CPU / GPU combo should work as expected. Although the Q9400 is a mid to low range processor, the GPU acceleration should be noticeable.

So yes, as requested above - give us a break down of what media types you have. Camera media and graphics on the timeline, and any FX that might cause slow down. The 8GB RAM 'may' also be an issue if you are doing a lot of HD work. RAM preview settings can also have an effect.

I have hd video .m2ts shot at 1080/60i (MPEG-4/H.264) and 2 standard Dv avi files. Footage on all 3 cameras were shot at widescreen 16:9.

I have a weird mix of cameras....Canon xa10, canon gl2 and Sony vx2100. Slowly trying to upgrade to all HD camcorders as my budget allows :)

I'm actually down converting the hd video, maybe this is what is causing my slowdown?

Do 2 Tests:

A] Start a new Veg, say "SD.veg" Samples from ALL your SD cameras, and match your project to the Media. Now, how does that look/preview?

B] Start a new Veg, say "HD.veg" samples from your HD camera, and match your project to the Media. Now, how does that look/preview?

If both Preview as you'd think they should, then render EITHER A] to B], OR B] to A] and insert the re-rendered files into the Project you want to work with.

This is an old Chestnut . . . . . Just 'cos Vegas CAN do mixed media, sometimes it's just better to ignore this and get the job done.

Cheers

Grazie

I upgraded to a GTX 460 a while back. I preview anything from DV, HDV, and AVCHD with no problems at 'Best half'. I found 'Best full' a tad laggy. Running Vista Business 64bit. Quad QR9650, 8gig RAM.

Must be my video card....

Even after I am done performing the multi-camera edit and am working with the video track the preview slows down to an unusable stutter even in the draft setting.

When I disable my GPU from the video preferences everything works fine. I guess my Card has issues.....??

All I know is my card supports OpenCL and is extremely fast, there should be no reason for such a slowdown especially when Sony states I should see an improvement :(

You could try and go back to a previous driver. I found after many hours of testing that the 275 driver was the best for my GTX460 card; faster then newer ones and I tested up to 29x.xx versions.

I've got a GTX470, CUDA2 compliant and an i7 OC'ed to 3.56GHz with 24 GB RAM (for music composing not for Vegas) on Windows 7 64bit and I notice that the auto-crossfades between still images are not smooth at all during preview . Best Full or Best Half.
Puzzling on such a powerful machine.

The minimum requirements also say: "•2 GHz processor (multicore or multiprocessor CPU recommended for HD or stereoscopic 3D)" with 2 gig of RAM.

Vegas 11 will work on such a system but it doesn't mean that it will work very fast. A GTX 4xx series card is just a minimum. You do not expect much from a duo core CPU computer even if Vegas 11 will work on it. The same applies to a video cards. You're not going to get the same kind of playback speed from a GTX460 than a 480, a 560, a 570 or a 580. The driver will not make much of a difference.

I have tried multiple video cards on the same computer and the difference can be quite drastic. The Radeon 5770 is on the list of compatible cards but I can tell you from experience that it doesn't help nearly as much as a GTX580. We are talking about a fraction of the power.
