Can't use CUDA to convert videos anymore after 340.52 update!
  3 / 3    
It seems like my previous post disappeared so I'll try again. I'm trying to use the CUDA Decoder functionality in TMPGenc Video Mastering Works 5 to work with my MSI GTX 970. I tried the methods that suggests me to add the Nvcuvenc.dll back from the older versions of the driver. However the trick doesn't seem to work with 344.75 drivers on a Maxwell card (MSI GTX 970). I can enable CUDA Hardware decoding after pasting the two files in their respective folders, but when I add any video to the project it gives the error (CUresult=400). Has anyone gotten Nvcuvenc working on a Maxwell card? I'm guessing the reason for removing CUDA support on consumer cards is to force professionals to buy their Quadro and Tesla cards. Can we get the files from the Maxwell versions of those cards and put them in the correct directories? If so, please share what drivers you used and which driver did you extract the Nvcuvenc.dll from. Thanks.

344.75 is the newest driver for my card (MSI GTX 970 Gaming). I'll try it again when the next driver update comes out.

so, on an i5-2500k & gtx970, what would the best/most like xilisoft video convert be? i always used xilisoft on my old 670 and used the cuda to speed things up and i loved it, all of my youtube page was reencoded with that method now that ive upgraded to the 970, whos oldest driver that i saw was like 340, which is still too new to have the old NVCUVENC active what am i supposed to do >? its taking me like an hour to encode an 11 minute 4gb mp4 with ffmpeg to h.265 with just cpu are there any complete, GOOD programs that are easy like xilisoft was that supports the max bang that the 970 has to offer?

I was told by nVidia support that v337.88 was that last drive version that actually had a working CUDA Driver. This really sucks as the card I purchase was specifically for that use and was only a few months old.

I think I may have stumbled across a solution which prevents Windows 10 from automatically updating the GeForce driver to 340+ -- without preventing other important updates from being installed. This involves editing the system registry, so attempt this only at your own risk: If a 340+ driver has already been installed, go to the Device Manager and roll back that driver. If you DON'T have a pre-340 driver installed, find and install that for your OS. 1. Right click on the Start icon (lower left-hand corner of the screen), then left click on RUN. 2. Enter REGEDIT as the name of the file you wish to open, click OKAY and then YES to confirm. 3. Click on EDIT, then on FIND and enter the number of the NVidia driver version (in my case, 337.88) 4. Ignore any instances of the driver version that you may find until you get to the following section of the system registry: HOTKEY\LOCALMACHINE\SOFTWARE\MICROSOFT\CURRENTVERSION\UNTNSTALL. 5. Look for the following DWORDS and change the value on each from 0 to 1: NO MODIFY NO REMOVE Hit the F3 key to find the next instance of your driver number (which should also be in this same section of the system registry), then repeat Step 5. Hit the F3 key again until you find no more instances of the driver number in this section of the registry. Exit REGEDIT to save your changes. Based on my experience, Windows Update will keep trying to install the new NVidia drivers but the system registry will prevent that from happening. Which means my video card's CUDA cores can once again be accessed by software packages such as Nero Video. YMMV, so good luck!

Previous drivers doesn't resolve the problem? Enunerated older version or older than 340.52? Probably I got on the solution. Uninstall whole Nvidia drivers package. Make sure that device is not recognised, or unplug PC from the Internet. Try to install driver via Device Manager. When I installed enlisted driver package, OS asked for that visa file nvcuvenc. On x64 you need to sometimes change dll filename to get prompt of missing file passed. And better copy into whole unpacked driver package this files from above. You make it by running installer once, and drivers are in C:\Nvidia\ and proper driver folder. Personally it didnt installed drivers for me, but resolved 7zip error during running usual installer. So I hit for this topic by accident.
