 -s means video size, -r means frame per second and -o means output
 
+The default of VVENC: Constant Quality is 32 and speed is medium.
+If you want to get smaller video size and lossy video, add -qp 38. (Not recommended)
+If you want lossless video without losing quality, use CQ 16-19 and preset slower. (Recommended)

+Lossy video/Smallest video size:
+```
+vvencapp -qp 38 -i out.yuv -s 854x480 -r 30 -o vvc.266

+Lossless video (without losing quality):

 # FAQ (known as Frequently Asked Questions)
 
 Are you real creator of VVCEasy?
-Yes... but I'm not creator of VVC, I didn't build VVC, so it was Fraunhofer that he built VVC.
+Yes... but I'm not real creator of VVC, I didn't build VVC, so it was Fraunhofer that he built VVC.
 
 Are you trying to work build of VVCEasy?
 Well yeah... it takes longer time to make VVCEasy easier, but VVCEasy is not yet finished until further/update announcement. I don't have employees, so I'm only one.
