Hi all
I'm currently having a problem with GPU rendering in Vegas Pro 14. In my system I have 2 GTX 970 cards in SLi but I cannot use them for GPU rendering because when I click check GPU it says no GPU available. Any ideas as to how to fix this?
Kind regards
Tom
i don't believe any nle uses sli - though with resolve you can dedicate one card to gui and other to rendering.
Tom,
What Codec are you using to render? GPU acceleration is not supported with modern cards on Main Concept AVC or Sony AVC. I'm not happy about this either...
I use Sony AVC/MVC in .MP4 format.

As I said: no GPU acceleration for you, except if you use an old GTX 5xx or AMD HD 6xxx.
Ah that sucks. A badly needed feature is this.
What time is needed to render 1 minute duration using GTX 970 ?
On my experience with AMD Radeon RX470, a minute requires 2.5 minute to render, while using Mainconcept, requires 4 minutes!

Hi,
Make sure you compare apples to apples. For instance Mainconcept's default setting is 2-pass encoding, which takes twice as long as single pass encoding. Depending on your options mainconcept can be faster than Sony AVC... or slower. And asking someone how long it takes to render 1 minute makes no sense at all, as it will completely depend on original footage, output format, and editing options (filters, zooming, etc...)
I have no CUDA support in Vegas Pro 13 and 14. But CUDA is available in the Movie Studio 12 edition!! Gfx card are ASUS GeForce 680. Suggestions?
Suggestions?
Switch it for an older one!

No: don't do that.
Rendering in only a tiny part of your work. Vegas actually uses GPU acceleration for most of its editing process: that's why the real time effects are so fast and good.
If you use an old card, you might be able to render faster but working with Vegas is going to be slower.
What you should do is pester / bribe / beg Vegas to implement GPU rendering in the H264 codec.

Are you saying that Vegas uses CUDA for time line preview rendering even if the VIDEO OPTIONS tab says "GPU Acceleration of video processing" is "OFF" (there is no way to turn it on).
And why the heck is it ON in my Movie Studio 12 program. Isn't this the same core prg...
The questions remains
Why doesn't the 680 card show up in the Options/Preference/Video menu under “GPU acceleration of video processing”?
No show in vegas pro 13 and 14.
Available in Movie studio 12...
I had a similar problem with my GTX 1080 - it didn't appear as a choice in Preferences, but I just updated the driver through Control Panel and now it's there in V14.
Yes, espen-braathen, update/reinstall your video card driver to get it to show up. This has been found to work in other similar cases.
As usual, there is plenty of confusion here between a) "GPU acceleration of video processing" in Options>Preferences>Video and b) GPU-accelerated rendering, in Encode mode in the custom settings for the Sony and MainConcept AVC encoders.
(a) is done by OpenCL, so you want a card that is good with that. AMD has the edge, although Nvidia can do it, and modern cards bring improvements. (b) is done with out-dated code optimised for cards with an architecture that ended with the Nvidia GTX580 (for MainConcept CUDA acceleration) and the AMD HD6970, so more modern cards don't bring improvements specifically for that or don't support it at all.

It's not so much that the architecture ended, but that the compatible card references are hard-coded in the code: if your card reference is not there then Mainconcept considers it's not supported.

Ah OK, that rings a bell. I have a feeling someone mentioned that could be modified. Might be imagining it though.
I believe that if you could make Mainconcept believe that your GTX 1080 is in fact a GTX 580 if would encode superbly!
Going to the secret "Internal" menu in Options/prefereces I was able to set GPU render to TRUE (was FALSE as default) and the GPU setting appeared in the rendering menu for Sony AVC again. But as you sais the rendering time was not improving after I selected the CUDA option vs CPU only. Well, at least I tried!
Regarding Nvidia vs AMD gfx cards I should have know this before my purchase a few years ago. The Sony Creative site was not much help at the time!
(I just assumed that 6xx cards shoud be supportes as well as the stated 5xx card. Bummer.)
Time to update the driver I guess.
Yes: if Vegas is your most important software to optimise then go with an AMD card and not an Nvidia as AMD have better openCL bang for the buck. At the high(-ish) end go with the RX 480 vs a GTX 1060-1080.
Thank you folks! After I upgraded the Nvidia 680 gfx card drivers the GPU acceleration was back in Vegas 14!
This has driven my crazy for the last 48 hrs!
