This software is meant to investigate performance and image quality of HW encoder (QSV) of Intel. 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.

• QSVEncC.exe ... Command line version supporting transcoding.
• QSVEnc.auo ... Output plugin for Aviutl.
