So, I simply check the staxrip's "Use QSVEncC as decoder", setting the resize and same nvenc encode options;
encoded 34404 frames, 338.14 fps, 265155.64 kbps, 45356.84 MB
encode time 0:01:42 / CPU Usage: 12.72
frame type IDR 34404
frame type I 34404, total size 45356.84 MB
encoded 34404 frames, 340.86 fps, 2255.76 kbps, 385.86 MB
encode time 0:01:41 / CPU Usage: 9.13
First 338.14fps with crazy amount of bitrate and size is QSVEncC decode usage.
Second 340.86fps is NvEncC encode usage.
But, QSVEncC VPP resizer is using better quality...the 8 tap polyphase thing?
Edit: In case you wanna know, it is a 24 minutes H.264 video without audio. So, I will not encounter the dreadful "Error in encoding pipeline".
