Use ffmpeg and x265( HEVC) to verify the Per-Title_Encode_Optimization by Netflix. I just test the file in 4K at http://media.xiph.org/video/derf/ (I try the Netflix_Narrator)
#Refernce Netflix tech blog: http://techblog.netflix.com/2015/12/per-title-encode-optimization.html
#Example Result
- Reduce Frame
- Down Sampling
- HEVC encoding with diff QP
- Decode HEVC
- Up sampling
- Calculate PSNR
- Generate picture PSNR vs Bitrate by gnuplot

#Usage
sudo bash script.sh [Vedio File Path] [Resolution 1] [Resolution 2] ...
#Example: sudo bash script.sh Netflix.y4m 3072x1620 2048x1080 1536x810 1024x540
#Defalut Configuration
- reduce frame to 128
- At begining, you should determine the interval of QP ( start with QP=0, which means the best quality and QP no more than 51)
- I jsut test the .y4m file with 4096x2160 and not try for others
