Mobile GPUs and CUDA encoding.

Hey,

I have a laptop with GTX860M (Maxwell). I have tried a few programs for video encoding (H264), however none of them is able to recognize my GPU and enable the CUDA encoding. Is this due to the Optimus? According to Nvidia gtx860 is CUDA enabled...

Can anyone suggest me a program that is working with mobile GPUs and able to encode videos? Right now all I get is 100% CPU usage and slow encoding.....

Best regards!

 

If i remember right Freemaker you can select cuda or intel dxva encoding or just plain cpu in the settings, make sure you untick or skip all the crap while you install it though.

I did not really see much difference between cpu and gpu encoding in speed thought but it might vary.

EDIT : what are you using to encode now! , I use the free handbrake but it`s cpu only at the moment.

Freemaker was one of the programs that I've tried. However I have only the DXVA option available as most probably the program is not seeing the nvidia due to the optimus (I have set the program to run on nvidia GPU but still no luck).

The fastest encoding I get is using the DXVA. With it a 4 min video is encoded in mp4(h264) FHD for 50 seconds.

I think that with CUDA I should be able to go faster.

 

Alright,

It appears that Nvidia has discontinued the CUDA support for encoding or whatever so... in order to fix it you will have to download the following zip https://www.mediafire.com/?pga9pqidcf9kq20 and extract it in your Windows directory, after that restart the computer.

Now I have the option to select CUDA, however it is way slower then my CPU/DXVA.

All the best.

 

Yeah I made a thread about this a while back:

Ok, unfortunately the CUDA encoding for me is several times slower then using the CPU. It apperas that the program is utilizing only like 10% of the GPU....

Can anybody recommend me a program for mp4 h264 encoding that utilizes the full power of the GPU (mobile 860m)... I am lost...

All the best!

 

I thought GPU/GPU accelerated encoding always sucked compare to CPU except quicksync~ (or games using shadowplay)

Probably look in to NVENC instead of CUDA.

 

I have 347.09 but the trick did not give me CUDA for amerisoft, not too sure I want it. I do know with the 6xx cards, other than 675, the GPU's were crippled.

I have found a program that utilizes the new NVENC. The program is called DVDFab 9. The latest version is working perfectly with my gtx860m as it supports H264. I was able to encode a hour and a half video in 3 minutes...

 

You didn't mention the application you were using? Does it specify GPU acceleration? Assuming Optimus is disabled, you may need to activate GPU acceleration manually. With Adobe products this has to be turned on, otherwise it will use strictly software encoding.

Some old school folks claimed this. However, programs optimized for GPU acceleration will give you identical product at a much faster speed.

 

True that, but only if such program exists and does no introduce additional bug.

 

Xilisoft Video Converter supports nvida and amd gpu`s for acceleration they have a free trial on their website, but it most likely only does a small part of the video, but it allows you to see if it works with your gpu.
