SONY VEGAS + i7 2600K + 8GB RAM + NEAT VIDEO = SLOW RENDERING?!

Dear community,

I've been having some off problems lately, and i want your opinions:

Here's my setup:

Sony vegas pro 11 x64
i7 2600k asus-stock-overclocked at 3.4ghz, 8core
Windows 7 ultimate x64
8gb ram gamers edition 1600mhz
msi nvidia gts450 1gb ram ddr5
normal sata-2 hard disk drives at 7200rpm, western digital

I have shot a live band playing with my Sony HVR-HD1000E at 1080-50i
The project is 2 hours long and has the following video fx:

neat video for noise reduction
sony color curves for brightness and contrast
sont hsl correction for desaturating the colors
sony color correction

My problem is that when i render at MPEG2-Blu-ray 1080p it needs 25 hours to export the project!

During render, Cpu load is average 30-40% which is nothing and ram is 8gb-ram.

What am i doing wrong ?

I have gpu acceleration enabled but even if i turn it off, it doesn't change a thing. Nor does exporting to interlaced makes it go any faster.

Take a look at this http://www.sonycreativesoftware.com/vegaspro/gpuacceleration

Since my cpu and ram aren't being stressed at all, i imagine it's either a bad setting in the project / software or the gpu being relatively old and slow, so If i invest 660 euros to get the asus nvidia gtx680 2gb ram which is a beast, will i see any worthy difference or will it be money thrown away?

Any experience with neatvideo?

I would deeply appreciate your inputs.

Thank you!

Nothing. From what I've read on a previous post, neat video takes an extremely long time to render even with a super-fast processor. Considering your timeline is 2hrs, it may just be the nature of the beast. I would render a 10sec test clip to make sure it will look the way you expect it to, check your timeline to make sure everything is correct, then render away. Good luck!

Sorry,I don't believe it would.

If you render your project using 2 passes encoder's settings that you can try to reduce your render time almost twice by spliting the render into 2 steps:
1. Render the project into temp file using loseless codec (lagarith for example).
2. Open the resulting file in Vegas and render it with settings that you need.

NeatVideo plugin is extremely slow (and very effective as well) and if you render with 2 passes encoding it does its job twice.
If you render it to a temp file (loseless) it will work only once.
Unfortunately, you need a huge amount of free space for the temp file.

P.S. This is just an idea, I haven't tried it yet :)

Indeed, and i have no problems with it. But cpu usages is continuously at 30-40% and ram is at 40% all the time so this is why i assumed it has something to do with the gpu. But it seems it doesn't?

Also, maybe i should mention that i haven't messed anything in the settings of the programme, the dynamic ram preview is by default set to 200 and maximum number of rendering threads is at 16. I generally read that by messing with those, you usually get negative results so i left them untouched.

Thanks guys

The key omission from your setup list at the top is version of Neat Video you're using.

As Bryan mentioned Version 3 (or now 3.1) is a much faster than version 2. Version 3 is at least 2x as fast as V2 (2.6 etc) when only using your CPU. Version 3 (released last winter) also now supports CUDA GPUs for another 2x to 4x speed boost (Version 2 didn't use GPUs at all)

It does add a lot of time to renders but the difference between version 2 and 3 is huge. Using only Neat Video HD projects in the 1.5hr range could take 30+hrs to render on my i7 2600 + 560TI. With version 3 the same projects take 6 to 8hrs to render (usually just run them overnight).

If you're using V3 there's a benchmark tool located in Tools/Preferences/Performance . That'll show you the FPS for each frame radius setting using different number of CPU cores and w/ or w/o GPU. Pick the setting that yields the highest FPS.

Based on those benchmarks you can also lower (or disable) the Temporal Filter radius. The default is one frame but if you change that to 0 rendering will definitely speed up. Depending on the project the temporal filter might not make all that much difference anyway.

Hope this helps a bit.

If Neat Video is something you use on a lot of projects a faster GPU with CUDA support is definitely something that will speed up rendering times.

Here's how they define the rendering speed upgrades in version 3:

It's not true.
The developers say: "The exact speedup factor can vary in the range x1.0-x2.5, depending on the filter and project settings"

In my case (I work with 1080-50p) the speed is increased by 20% only (1.2 times faster). However, I use AMD CPU and do not have NVidia video card.

Source: 1080-50p
Output: 1080-50p, Mainconcept AVC, High Profile, 2 passes encoding, Avg Bitrate: 28Mbps
NeatVideo settings: Adaptive Filtration, Temporal Filter Radius = 2, Noice Reduction Amount: 100/70/40, High Quality Filtering, Hight Resolution, Sharpening: 50/20/10, Conservative. NeatVideo performance 1.93 frames/sec.

NeatVideo filter is applied not for all fragments (~50% fragments).
~14 mins (~42000 frames) video was rendering for 11 hours in version 3.1 and 14 hours in version 2.6 (without my trick, for longer project I will try to use it)

AMD Phenom 840, 8 GB DDR3 RAM, AMD 6850 Video, 7200rpm HDD.

The long render time is not exactly my problem.

Intel i7 2600, 3.4GHz, fast RAM -- 6.4fps with radius=1. Intel i7 2600 is much faster then my CPU (and more expensive).
