This software is meant to investigate performance and image quality of HW encoder (NVENC) of NVIDIA. There are 2 types of software developed, one is command line version that runs independently, and the nother is a output plug-in of Aviutl.

  • NVEncC.exe ... Command line version supporting transcoding.
  • NVEnc.auo ... Output plugin for Aviutl.

System Requirements

Windows 7, 8, 8.1, 10 (x86 / x64)
Aviutl 0.99g4 or later (NVEnc.auo)
Hardware which supports NVENC
NVIDIA GPU GeForce Kepler gen or later (GT / GTX 6xx or later)
※ Since GT 63x, 62x etc. are renames of the Fermi generation, they cannot run NVEnc.

NVEnc required graphics driver version
NVEnc 0.00 or later NVIDIA graphics driver 334.89 or later
NVEnc 1.00 or later NVIDIA graphics driver 347.09 or later
NVEnc 2.00 or later NVIDIA graphics driver 358 or later
NVEnc 2.08 or later NVIDIA graphics driver 368.69 or later
NVEnc 3.02 or later NVIDIA graphics driver 369.30 or later
NVEnc 3.08 or later NVIDIA graphics driver 378.66 or later

Precautions for using NVEnc

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND.

The output from NVEnc may not include the max_dec_frame_buffering field, which might cause problem in some playback environments.
