High Efficiency Video Coding (HEVC), also known as , is a video compression standard designed to succeed H.264 (AVC). It offers significantly better data compression while maintaining high visual quality. Hacker News Key Advantages Storage Efficiency : HEVC can reduce file sizes by roughly 50% compared to H.264

  • Transform & Quantization: Residuals undergo DCT (Discrete Cosine Transform) on quad-tree blocks (4x4 to 32x32) followed by scalar quantization.
  • Entropy encoding: Context-Adaptive Binary Arithmetic Coding (CABAC) produces the final compressed bitstream.
  • Loop filters: Deblocking and SAO are applied to the reconstructed frame to serve as a reference for future frames.
