Hi All

Yesterday whilst browsing the forums I saw a thread about encoding video and someone suggested Freemake as a good piece of software so I thought I'd give it a whirl.

WHen I saw it was CUDA enabled I was intrigued as I ave heard that it can make quite a difference with encoding times.

Last night I gave it a try and in the options clicked a tick box for it to use CUDA, and set it to re-encode a cideo from MKV to avi. There was no visible sign that CUDA was being used and the speed seemed pretty normal.

I tried googling to see if there was an easy way to see if CUDA was working but didn't find anything.

I did however stumble across a forum post where someone mentioend having used PC Wizard to check their pc was CUDA capable.

I downloaded PC Wizard and had a look, as I thought, my Graphics card (Geforce 570) is indeed CUDA enabled but when it came to the benchmarking for CUDA it got a score of 0, which baffled me a bit.

I have the latest Nvidia drivers and all seems to be well with the pc but I'm a bit stumped by CUDA and from a good bit of googling I really didn't find anything very useful about how to get it working etc

Can anyone point me in the right direction for a simple tutorial about getting it working, or does anyone know if there is a simple way of telling if it's working? Or can anyone explain why my CUDA score was 0 on the PC Wizard benchmarking?

Thanks in advance...
 
I just tried the CUDA benchmark and got 0 as well. CUDA is definitely working on my system because I run Folding@Home on my GPU, which uses CUDA. I think there's something wrong with that benchmark.
 
If you wanted to see if it was working, you could download a program which shows you the GPU utilisation (like EVGA Precision), and see if it increases during encoding?
 
it could be that cuda can only be used in certain tasks?

i have just downloaded freemake myself and when converting to avi i get about 60% to 80% gpu utilization but if i convert to dvd it wont use any of my gpu

Good plan, didn't really know about such software but yes, will give that a go!

hmmm, will have to do some experimenting!
 
I installed freemake based on your other thread to see what it was like.
I have an ATI card. On the screen that shows the CUDA logo it actualy says that it isnt compatable with my system so of course it wont be used. If your not seeing this message it must mean that it is enabled.

It could just be that with the current crop of CPUs they chew through stuff so fast that CUDA isnt used even when enabled, or just makes zero difference.

In a related note I deinstalled freemake as with the 3 different files I tried 2 were choppy. I went back to using DVDFab for my tasks, i dont use MKVs though.
 
Going by EVA precision it seems that CUDA was working as my graphics card usage leapt up when the CUDA option was ticked.

As to how much of a difference it made speedwise Im not sure as I didn't do any proper comparisons but it seemed like it was much the same pace as the cpu really.

Re videos being choppy with freemake, again, not really used it more than a couple of times, I just saw it mentioned in a thread here.
