Why H.265/HEVC is Better

Technical Improvements:
  • • Larger coding tree units (CTU) up to 64×64
  • • 35 prediction modes vs 9 in H.264
  • • Advanced motion compensation
  • • Sample adaptive offset (SAO) filtering
Practical Benefits:
  • • 40-50% smaller file sizes
  • • Native 4K/8K support
  • • HDR and wide color gamut
  • • Better streaming efficiency

H.265/HEVC Advantages

  • • 50% smaller files: Same quality as H.264
  • • 4K streaming: Practical bitrates for UHD content
  • • HDR support: 10-bit color depth encoding
  • • Mobile friendly: Lower bandwidth requirements

Modern Features

  • • 8K support: Ultra-high resolution encoding
  • • WCG/HDR: Wide color gamut and HDR10/HDR10+
  • • Adaptive streaming: Better quality scaling
  • • Future-proof: Next-generation codec standard

H.265 vs H.264 Comparison

4K Streaming

  • • H.264: 25-35 Mbps required
  • • H.265: 15-25 Mbps sufficient
  • • Savings: 30-40% bandwidth
  • • Quality: Equivalent or better

1080p Streaming

  • • H.264: 6-8 Mbps typical
  • • H.265: 3-5 Mbps sufficient
  • • Savings: 40-50% bandwidth
  • • Mobile: Better for data limits

Processing Requirements

  • • Encoding: 2-5x more CPU intensive
  • • Hardware: Requires modern GPUs/CPUs
  • • Decoding: Newer devices needed
  • • Trade-off: Quality vs processing power

Platform Support Status

Full H.265 Support
