The question is how much of the problem belongs to SCS VS NVidia?

I can use driver 296.10 with Vegas 12 just fine with my 560 ti and Windows 7. If I try the latest driver I will have a lot of issues. I can set the preview ram to zero and get stable with the time-line but slower. If I render a long project it will stop rendering at some point. Turn off GPU and the render will finish just fine but of course be slow.

I use the 296.10 driver and the above problems do not happen on my system. I can even set the preview ram to a high amount and all will be fine. The 296.10 driver will cause my GPU to not be recognized in Vegas 12 with Windows 8.

Nvidia did a bad number on the 600 series as far as Vegas is concerned so those are out.

NVidia is a lot more interested in games than NLE's. So for now and for me it is Windows 7 and driver 296.10.

This is a case where the latest driver is NOT the best driver!!!

Can SCS fix the nonsense that NVidia does? I do not think so!

Does NVidia really care? I do not think so!!!

In the future, I will forget NVidia...

"In the future, I will forget NVidia"

Where is the evidence that AMD is any better?

I already forgot AMD...

CPU only looks like the best way to go.

By the way, NVidia just released a new driver. just for kicks I gave it a try. Same old problems.

I went back to 296.10.

My next system build will not use a GPU. I was hoping to avoid a GPU on my current new system (System specs not updated yet) but is a bit too slow. Since I really do not need Windows 8 and can make things work fine in Windows 7 I will keep things as is for now.

I am using Vegas 12 build 394.

"This is a case where the latest driver is NOT the best driver!!!"

The trouble with this though, is that most software creators e.g. Adobe, and I shouldn't imagine Sony to be any different, always respond to problems with the age old reply - 'are you using the latest drivers?' I have yet to read over umpteen years of using Adobe them making any mention of the fact that one should revert to previously installed drivers.
They've really got you by the short and curlies here in that if you're not using the latest drivers then their not obliged to help sort your problem. Just my 2c worth.

296 was stable, everything upto, but not including 310.9 was screwed.

310.9 'seems' to be working fine (though with a 550 my i7/920 is faster rendering).

notice they just released an new driver yesterday!

anyone game out there ;-)

@OP: Yes I can commit to GPU acceleration and I do it since VP11. Even with a 3930K the GPU acceleration is a huge improvement over CPU only. And yes, drivers do make a huge difference and I am also using 296.10. I used 275.33 too until I installed a GTX 560Ti along with my GTX570. The 560Ti is unfortunately not fully supported by the 275.33 driver but it is for me the most stable and fastest driver to date.

I still believe that many of the issues that have been reported here are hardware & driver related rather then a VP software issue. I just wish we could use SLI to further enhance the GPU acceleration especially with the latest PCIe 3.0 standard that allows for 32bit lanes. Also from personal experience you need to have at least a GTX from the x6x series or higher, (46x, 56x) to see the difference and the latest GTX 6xx are not well supported either. I have also helped users to get their systems to achieve proper acceleration; some didn't even know that you actually have to make changes to the default templates, MC AVC for example, to get CUDA rendering in the first place. Those are the areas where I think VP needs improvement; proper explanation of all functions, especially the hidden ones after all it is a software for the "professional".

GPU acceleration, CUDA in NVIDIA's case is something that I fully support and use daily.

Hi OldSmoike: I am considering a new system based on the Intel i7-3970x Extreme processor (currently the top of the processor line) and would appreciate some advice on a graphics card from NVidia for CUDA support, specifically what would you suggest in terms of a particular card model. Also, I currently have a single monitor/G-card but thenew system will have two monitors: I would like to see my Preview Window in a separate monitor and the rest of the VP interface in the other monitor. However, the question I have is should I get a system with two separate video cards, or a single card with dual DVI ports. Cost is always of concern so the less costly alternative that allows me to configure VP to see the Preview Window in one monitor with the rest of the VP interface in the other would be preferable. Thanks for any suggestions on this.

You can click my UserName to have a look at my current system; I just updated it. I am not sure if the additional cost for a 3970x over a 3930K is justified by the additional performance. I would rather spend money on a second GPU or a BM Intensity Pro and a HDTV that can handle 1080p or at least 720p. I already use two monitors for things like text generation, color correction and so on and still would like to display more. VP12 allows for all that with the enhanced ProDock. The reason I would go with an actual TV, again depending on what your final delivery is, has to do with the way VP handles de-interlacing/interlacing... another can of worms.

There are 570cards that take up only 2 slots, mine uses 3 but I can still have the second GPU in a full x16 configuration on my motherboard, just no more slots for anything else.

Edit:
Very important is very good PSU, 1000W or so and a casing with lots of cooling.

Yes, I agree: Will watch out for the PSU and internal cooling.

Thanks for the suggestions OldSmoke.

Firstly I don't see why it's our job to bring this issue to SCS's attention. If they're not getting the message from all the posts here then any other effort is futile. If they were to ask here for help in diagnosing the problem then fair enough. So far the stoney silence fails to impress me at all.

Secondly shifting the blame to nVidia and possible dodgy drivers is bad reasoning.
SCS and they alone elected to provide this feature. They decided to use OneCL rather than CUDA knowing that OpenCL is not well supported by nVidia.

Bob.

I have to agree with Bob. Speaking only for myself, it's getting very tiresome being a Sony apologist when the evidence they are fully committed to crafting an "insanely good product" is less than compelling. It's true the hardware and software ecosystem they inhabit is complicated and sometimes unforgiving, and it's true their competitor's products are also mostly not "insanely good", but nevertheless Sony often seems to be mostly plugging today's leak in the dyke while chasing a new feature set to satisfy an apparently unrealistic release schedule driven by a revenue stream goal. Sigh.

drmathprog.... "Sony often seems to be mostly plugging today's leak in the **** while chasing a new feature set to satisfy an apparently unrealistic release schedule driven by a revenue stream goal."

I couldn't agree more. I wish there was a 'super like' button to click on.

I've been trying to send this message to all the people I know at SCS. I've met with them at NAB, I've sent emails to their project lead, marketing guys... It's all ignored.

They honestly believe it's ok to release software based on dates in a calendar with no concern as to how full their bug database is. None. I've given up. But I felt compelled to support your statement here. It's sad to see software you love fall into a bug filled mess.

Thank you Farss, VideoITguy, and VanLazarus....I appreciate you comments.

" It's sad to see software you love fall into a bug filled mess." AMEN !

I agree that this problem is very complex, and maybe will never see true stable GPU acceleration. The only reason i decided on GTX 570 was due to Sony's approved list and it fit my budget.

Well maybe it's GPU off ....real shame, because i noticed Neat Video and Mercalli plugins render super fast.. My time would be better spent editing with out freeze up and crashes.

I just can't recommend Sony Vegas like I have in the past.

Hi Bob.

Do you select "Render using OpenCL if available" or "Render using CUDA if available" when you render with MC AVC? For NVIDIA it is CUDA and not OpenCL and that has always worked flawless for me; in VP11 as well as VP12.

I never noticed this setting in Vegas 12, I know V11 will have a CPU ONLY or CPU and GPU if Available. I will try this tonight for sure, but V12 does lock up during editing process with GPU enabled (preview, adding plugins like Neat Video, Mercalli etc.)

Certainly will try rendering a short clip tonight

I stopped a 2 hour render after 24 minutes.,
Rendered a small section with success (1 minute clip)
Third attempt for a small section and had a lockup (1 minute clip)

So I guess it is a little unstable for me.

Which driver are you using? Try a simple clip without any effects or transitions, just to test where the problem could be.

I have delayed getting a faster GPU for over a year now because of all of the problems others have been reporting... (My GPU is 4+ years old...) I also still mainly edit & render in Vegas 10e because 10e uses 100% of my CPU during renders whereas V11 & V12 only use about 60%...

I have a (3) year-old 6-core 980X CPU overclocked to 4.0ghz. A typical 1-hour HD project takes about 1-hour to render to Blu-ray Mpeg-2 using the MainConcept codec. I have not found a way to get V11 or V12 to match this speed regardless of the processor (3930K, etc.) or video card (GTX 570).

If others are getting faster than 1:1 HD to Blu-ray Mpeg-2 renders, I would love to know your system specs. As for me, I have no plan to upgrade until the next batch of CPUs & GPUs are released and confirmed to speed things along...

I have a HDV and AVCHD mixed project, Z1U, Z5U and NX5U footage, multicamera timeline with color correction, transisitons (about every 10sec), some pan/crop, brightness & contrast, sharpness and a few level corrections. Also 4 audio tracks. I rendered a 10min sample form this project using Mainconcept BluRay 1920x1080-60i, 25M template in 5min 15sec. which is about twice as fast. You can find my systems spec by clicking my UserName.

Hey OldSmoke,
Your timeline sounds a lot like my typical layout. I am curious; so you shoot interlace or progressive?

" I rendered a 10min sample form this project using Mainconcept BluRay 1920x1080-60i, 25M template in 5min 15sec. which is about twice as fast."

I will spend a little time on bypassing my effects to pinpoint the problem. More than likely will jump back to V11 to get my project out (since you helped me with setpoint software conflict)

BriceWilliams2

I am glad I could help. So far, since 2007, I have only shot in interlaced. My previous camera, HDR-FX7 didn't do any progressive and when I got my Z5U I did a couple of test shots with all the offered recording modes. I found 60i to be the most suitable for my purpose, mostly sport events such as figure skating. At 30p everything becomes choppy but if I would shoot an interview or documentary then I might choose it. When I looked at my test shots, specially outdoors 30p seems to have more color depth at the same 4:2:0 bitrate. Maybe the longer exposure does contribute to it?

As for effects, I must admit that I don't use any 3rd party plug-ins at all. Only last week I installed the NB Titler Pro that came with VP12 just to find that it immediately crashed Vegas on the first try to make a title. I haven't come across anything that Vegas can't handle on its own, might take more then one FX to get there but it can be done. The only 3rd party software I use is Vegasaur for its transcoding function that allows me to render DVD, BluRay and AC3 in one go.

Been fiddling around with Vegas Pro again after having spent the last 3 months with Premiere CS6. I never had issues rendering with CS6 and had better color results too. But, renders took forever. A 10s clip took almost 4 minutes to render.

Now back to Vegas Pro 12 and renders are absolutely flying! Almost 4-5x faster using my GeForce 560 GTX and the latest Nvidia drivers. But, I tried a longer project today and started seeing hangs during render. The hangs seem to go away once I reduced Preview Ram back to 0, though renders are slower now but still much faster than CS6.
