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.

Windows 10 (x86 / x64)
Linux (x64)
Aviutl 1.00 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.

Option list and details of NVEncC

Result of --check-features, a feature list returned from the driver. May depend on the driver version.

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.
