The high-quality preset is considerably slower but produces fewer compression artifacts. The published 8× rating is achievable with the NVENC high-performance preset, which sacrifices compression efficiency and quality for encoder throughput. Actual throughput varies on the selected preset, user-controlled parameters and settings, and the GPU/memory clock frequencies. NVidia's documentation states a peak encoder throughput of 8× realtime at a resolution of 1920×1080 (where the baseline '1×' equals 30 Hz). The first generation of NVENC, which is shared by all Kepler-based GPUs, supports H.264 high-profile (YUV420, I/P/B frames, CAVLC/CABAC), H.264 SVC Temporal Encode VCE, and Display Encode Mode (DEM). (In H.264, NVENC always has B Frame support, max 4096x4096 resolution, and max 8-bit depth) NVENC has undergone several hardware revisions since its introduction with the first Kepler GPU (GK104). 1.6 Sixth generation, Turing TU10x/TU116.1.5 Fifth generation, Volta GV10x/Turing TU117.My guess would be to try constant quality RF23 or RF25 and see what you think after comparing them with the WMV files.

Maybe grab a copy of MediaInfo and import your WMV file and post a screenshot of what you have so we can see the video file properties. Im not sure what constant RF setting you would use for converting wmv to Avi, but what Avi are you outputting to, if i was you, try h264 in an mp4 container, it has excellent player support.ītw, what resolution, video bitrate, and audio has your WMV source files got ?

I now convert to 720/50p mp4 using RF18 in handbrake, and RF23 in XMedia. I believe XMedia uses the ffmpeg x264 encoder where handbrake doesnt, meaning the constant RF settings will be different. With handbrake i can set a constant RF quality of 20 and i get 6Mbps average, if i use RF20 in XMedia my same file is 9Mbps, so i adjust the XMedia RF to 25 and i get almost the same 6Mbps result as handbrake. I am converting 1080/50p m2ts to 720/50p mp4 but it is still relevant. Hi, i have been using XMedia myself trying to compare to handbrake, and i noticed one thing with quality preset.
