Cannot Load nvEncodeAPI64.dll

[mkrassner]

Hello,

Long time audio converter customer and newbie video converter trial customer (Thinking of purchasing). I can convert using non Nvidia but want to use my internal Nvidia card and keep getting the error below. Any help would be appreciated. I have the 391.35 Nvidia drivers currently installed. Thank you!

Not all nvidia cards are supported you would have to check with nvidia which cards are.

Hi,

I have fallen into the same trap:

My Lenovo P53s has an NVidia Quadro P520 GPU, According to the video encode and video decode list from NVidia the P520 GPU has no hardware support!

See the list here:

https://developer.nvidia.com/video-encode-decode-gpu-support-matrix

This is a real disaster for a "mobile workstation"...

So, no GPU acceleration possible with this laptop until the Intel hardware encoding is supported by dBpoweramp Video Converter...
