Sony Vegas 13 + GTX 750 TI + CUDA CORES

[Dave Osbun]

If I remember correctly, Vegas does not use Cuda for rendering at all, it uses OpenCL. AMD Radeon is the card of choice.

Nop, AVC(MP4) (don’t remember well the exactly codec) is capable of using the option of “Use CUDA if avaiable”, “Use CL if avaiable” and “Use CPU only”.

Also there is a tab on the codec where the codec verifies if Your card have CUDA, and it says “CUDA Avaiable” after clicking on “Check”

You did not mention which render as file encoder you were trying to use. Only a couple support GPU at all. Mainconcept AVC does not support newer GPUs like yours and will not use it and will fall back to only using CPU.

Vegas itself will use your GPU for generating the video stream with your effects, transitions and such which your video pref GPU option is enabled. This always happens. Playback or encoding a file. How much this amounts to depends on what you are doing on your timeline. The old Vegas GPU demo project used lots of effects and compositing.

Only a couple of file encoders support GPU and they have their own independent options to enable/disable GPU usage. Mainconcept AVC and Sony AVC. Sony AVC does not use the GPU for much and there is not much of a performance gain.

I was using the AVC/AAC (MP4) with the option of render using CUDA.

It takes 18seconds to render 5 seconds of vídeo without any effect. This is ridiculous. I refuse to give up to it. My card isn’t even that new…….

2 hours rendering with 100% CPU is gona kill my computer imaturally.

I see a lot of people complaining about models not working to render on vegas.

There isn’t any version of vegas or anything in this world that can handle this?

I see i’m going to adobe premiere soon…..

[Ricardo Farah] “I was using the AVC/AAC (MP4) with the option of render using CUDA.”

This states nothing. As I previously stated there are two (2) AVC encoders in Vegas. Taking a guess, it sounds like you were using Mainconcept AVC.

[Ricardo Farah] “It takes 18seconds to render 5 seconds of vídeo without any effect. This is ridiculous. I refuse to give up to it. My card isn’t even that new…….”

Mainconcept AVC only supports up to Fermi architectures. Yours is Maxwell. Which is two architectures post Fermi. Kepler is in between.

Of the AVC encoders in Vegas, Sony AVC is twice as fast as Mainconcept when running on CPU. An external encoder like x264 is much faster than either of the above.

[Ricardo Farah] “2 hours rendering with 100% CPU is gona kill my computer imaturally.”

Unlikely, assuming you have appropriate cooling, but do what you feel is necessary for you.

Something’s possibly not right with your system. I have an i5 3570k (not over clocked), a Radeon HD 7850 graphics card and 16gb RAM and when I use the MainConcept 1080 for internet render option, my render times are close to 1:1 (a one minute clip takes about 1 min 15 sec to render). My original footage is Sony MTS files 24mb/s and my render options are almost the same data rate as the original clips.

No…there isn’t…..i have been able to play games on high graphics and preview on vegas but when it comes to render my CPU takes it all.

Everything is OK.

Do You know if there is any other format that Vegas can Output using CUDA on my architeture?

Here is a clue: https://www.anandtech.com/show/7764/the-nvidia-geforce-gtx-750-ti-and-gtx-750-review-maxwell/21

Sony listed the HD5770 as minimum back in on Vegas 11. Your card is well below that card with OpenCL performance, and latest cards like the r9 290x are so far past the 5770 its not even funny.

Your CPU with intel quick sync enabled would be a faster render than the GPU. That GPU is just not that great. Just edit CPU with that configuration.

Also what is your source media? There is no 60FPS, there is 59.94. So unless your source material is actually recorded true 60fps, you will be doing some conversion which will be slowing your renders down.

Not exactly sure how NVidia gets away with advertising OpenCL support when its all so bad. I think they must have a qualification driver set, then gimp the production driver to steer people at CUDA. AMD and NVidia play a mean shell game.

As others have suggested, Main Concept AVC won’t support any new GPUs. Yes, it will claim to use OpenCL or CUDA, but it’s kind of bypassing the whole point of those systems, and hard-coding for specific GPUs. If you have any GPU made much after 2010, you’re SOL — it probably would work without their GPU check, but they simple disable GPU rendering for any GPU not on the list.

Vegas does use OpenCL to accelerate its internal rendering. That’s not going to prevent your CPU from going to 95-100%, but it does make things faster, both in preview and final rendering. This is not controlled via the rendering plug-in, it’s on Video tab of the preferences dialog, look for your OpenCL card being listed there (nVida include OpenCL in their CUDA drivers).

There is absolutely nothing wrong with running a properly designed PC at 100% CPU for hours, days, or even weeks. That’s what you want when rendering — that’s the best your PC can do. The only reason using OpenCL or CUDA in a rendering pipeline like Main Concept’s doesn’t let you PC get to 100% is pipelining inefficiencies… there’s plenty of work to do, but without being more multithreaded, the CPU ends up waiting for various GPU tasks to complete, resulting in some “dead time” on the CPU.

A far better way to tell if your GPU is helping out: actually monitor the GPU, don’t simply assume it’s not doing anything because the CPU is fully occupied. Run something like GPU Shark to monitor GPU activity during a render. It’s also quite true that the places that OpenCL is used by Vegas apply to the compositing and plug-in pieces, as mentioned, leaving the format-specific rendering to plug-ins like Main Concept. So if you are simply rendering one format to another without any image processing or compositing, the GPU can’t help you a great deal. If you’re doing something complex like the old “Red Car Demo”, it’s going to help quite a bit.
