Vegas Pro 12 Render takes too long

[Paul Anderegg]

I am going to guess you know enough about the program to have selected the proper GPU settings etc……..can you tell us what your original file/s format specs are, and your final output….I am assuming standard mpeg2 DVD?

I render DVCPRO AVI files to SD MP4, and it takes Movie Studio 12 about 30 seconds per minute to render on my new i7 laptop. My old i3 laptop does the same task at about 1 minute 30 seconds per minute, so hardware does make a difference!

I made a 35Mbps 1080i MP4 file to test rendering speeds if I upgrade to an HD camera, and it takes about 45 seconds to render a minute of that to SD MP4.

Hi Paul.
I am using Vegas Pro 12
My settings In Tools – options – Video are set to
Dynamic Ram 200MB
max rendering threads 16
GPU Acceleration of Video processing – (set to my Nvidia Graphics card

My source files are NXCam AVCHD, M2TS files
I am editing and trying to render the finished project to the DVD Architect template

I customized the template settings using a bitrate calculator and i am trying to render my timeline. My 11 minute test movie is taking 17 minutes to render.

My computer is an i7, 3.4ghz with 8gb of ram and windows 7 64 bit
I have a Nvidia GeForce GTX550 1gb graphics card

In vegas 11, the render time was approximately half the time of the movie

After speaking with Sony, I was advised go to the OPTIONS menu, go to PREFERENCES, then the VIDEO tab.
by the option for GPU acceleration of video processing, make sure it is set to off

This worked.

Thank you Sony Creative Software support staff!!!

That makes a lot of sense……perhaps that it a Sony “inverse GPU” feature! Haha. When I uncheck my GPU acceleration, the rendering takes an extra 4 seconds per minute, go figure.

Did Sony explain why you should turn off GPU? Do you have an incompatible or trouble-prone card?

It’s interesting that an NVIDIA GeForce GTX550 degraded the performance over an Intel Core i7, 3.4ghz CPU. I know people are using the GTX570 with good performance. I guess the GTX570 is more powerful than the GTX560 which is more powerful than the GTX550 which apparently isn’t as powerful as a Core i7. This is the problem with hardware assistance… the hardware that’s assisting needs to be more powerful than the hardware you already have. 😉

I suppose that means my Gforce 9600GT needs shut off too. 🙂 Seems like this feature should be “hardware assist” with *assist* being a keyword. Assist would help render the extras on top of the normal CPU operations, not slow things down.

Yea, that would look to be a “bottleneck”.

[Andrew Phillips] “Seems like this feature should be “hardware assist” with *assist* being a keyword. Assist would help render the extras on top of the normal CPU operations, not slow things down.”

It hands the task over to the GPU. It doesn’t evaluate the GPU to see if the CPU could do it quicker. It’s up to you to configure your system properly where the GPU is more powerful than your CPU. If not, it’s like you are delegating the job to the slowest member of the team. Either replace that member or stop delegating.

Makes sense, now if only there was a cross reference comparing all possible GPUs to their matched CPUs we wouldn’t have to guess. I wonder and guess that the speed of the render relies on the type of processing that’s going on in your timeline. Making the decision to use GPU that much more unpredictable. I’ve got a 580 and made the switch to GPU… now I question if that’s the right choice. I’ve only got an old Core i7 920 @ 2.67GHz so I thought the newer GUP would be the right choice.

Yea, I don’t think it’s a guaranteed pairing of this GPU with that CPU. It also depends on how the software uses the GPU. My only points was that pairing a modern day CPU with a 3 year old GPU is asking for trouble. I agree that it would be nice to understand how Vegas Pro performs with various GPU’s and CPU’s.

On Sony’s GPU Acceleration page they do compare the NVIDIA GeForce GTX 570, AMD Radeon HD 8670, NVIDIA Quadro 5000, and AMD FirePro V8800. That should at least give you an indication of relative performance using an Intel Core i7 960 3.2 Ghz CPU.

BTW, this is one of the reasons why I would recommend the NVIDIA GeForce GTX 570 if you can’t afford the NVIDIA Quadro 4000 that I have. At least you know that Sony tested with it! 😉
