3. Objective
This project discusses the performance comparison of HEVC and H.264 using various test sequences based on various metrics such as PSNR, BD-rates and computational time.

4. About HEVC
High Efficiency Video Coding (HEVC) is currently being developed as the latest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. [9]
The HEVC standard is intended to provide significantly better compression capability than the existing H.264/MPEG-4 AVC standard.[9]
HEVC is said to double the data compression ratio compared to H.264/MPEG-4 AVC at the same level of video quality.[9]

9. About H.264
H.264 is a block oriented motion compensation based video compression standard developed by ITU-T Video Coding experts group (VCEG) together with the ISO/IEC JTC1 moving pictures experts group (MPEG). It is best known as being one of the video encoding standards for Blu-ray Discs.[8]

11. Salient Features of H.264 [13]
Variable block-size motion estimation. It subdivides the frame into non overlapping fixed size blocks.
Quarter –pixel accuracy motion estimation.
Motion vectors over picture boundaries.
Multiple reference frame facility.

36. Conclusion
The performance comparison of HEVC and H.264 is done based on various metrics such as bitrate, PSNR and total encoding time at different QP values. The encoding time decreases as QP value increases. Various graphs are plotted on the comparison of HEVC and H.264. As per the observations the bitrate of HEVC is higher when compared to H.264. HEVC takes more time for encoding when compared to H.264 and PSNR is high for HEVC than H.264. HEVC is more complex when compared to H.264.
