Your Graphic card has to support CUDA. What is your Graphic accelerator card?

HI GPU, card is Nvidea GTX 580 CPU , AMD phenom x6 1050 ,16 gig of ram

Hi,
goto preferences and see if hardware and check either opencl and/or hardware decoding checked.
sometimes depending on the videos imported some rendering is automatic with cuda and if your system is fast enough without doesn't kick in.
I have the geforce 560t graphic card with the latest drivers.

Hi James1. I tried it all. MTS2 files are imported, put into timeline ,cut and edited, stabilized all, 4.8 gig video.Click produce button to produce to file.
1..Nothing enable . in 10 minutes cancelled it, read, time remaining 2.11.53 hrs 7% ( same file)
2. Hardware video encoder enabled in 10 minutes cancelled it, read 1.53.52 remaining 8% (same file)
3. SVRT enabled, in 10 minutes cancelled it, read , time remaining 2.09.55 7%. (same file).
4. Trail version Sony Vegas 10. in 10 minutes cancelled it , read ,time remaining 0.45.62 18% (same file)
When producing with Power Director the CPU was running 100% at all times ,with notices popping up stating High handle usage and high CPU.
With Sony the CPU was running at 68% to 75% and in 10 minutes of producing was 50% quicker.
That proves to me the GPU Cuda was working as well as the CPU. I hope you can steer me in the right direction as i liked editing with PD 10 better. Graeme

Try this Beta driver

Latest GeForce Beta Driver
Version: 295.51

I see you are using the latest released, should work, but then it may be worth a try. Intel Core i7 3770K 3.6 Ghz,
GTX 680, 2 X Benq23 3D monitors,
6G DDR3, Win 7 64, Win 10 (Insider) 64
PCIE SSD, Intel Sata SSD 2 500 Gbyte Seagate,
Minoru 3D WebCam, NVIDIA 3D Vision-Ready

I think the issue is you "stabilized all". In PD that is a CPU function and will add loads of time and CPU load to the rendering process when used on long durations of video.

I'd suggest to actually compare, run your test with a shorter TL and run your tests with just the video/edits/output that CUDA supports and look at total produced time to see if its working fine for you. You could also monitor GPU card for GPU activity as well.

Thankyou Jeff. How do I find and use Nvidea monitors for the GPU on my computer.

Graeme

Back again . Found the gpu monitors on window gadgets and installed.
1. the cpu running at 100 % and ready to blow up.
2. The gpu at the same time, as follows, GPU clock 0 Mhz 63degreee C usage 3% (maximum I noticed).
Memory clock 2005 Mhz. used0.0 Free1.500 Total 1.500.
Shader clock 0 Mhz
Disabled stablelisation and helped producing by 1 % The CPU went down to 89% to 100%
Disabled video denoise helped by 15%
So the question remains how can I get the GPU to do more.

Can you provide some details about your source footage format (mediainfo), and what exact profile you are producing to. Also a picture of your TL and "produce" window details would help. I still suspect you are applying some effect or producing to a format that is not CUDA capable. Did you select as a test video/edits/output that CUDA supports as suggested and look at GPU and see if it is utilized?
