Why is H.265 better than H.264 for exporting 4K video?

Which video codec should you use for high-quality 4K streaming?

Compare top video codecs to find the ideal format for your production workflow. Learn how H.265 and VP9 deliver superior 4K compression over standard H.264.

Question

Which codec supports 4K video and offers better compression than H.264?

A. H.264
B. H.265
C. VP9
D. MPEG-2

Answer

B. H.265

Explanation

This format fully supports 4K video and achieves significantly higher compression efficiency than H.264.

High Efficiency Video Coding

H.265, also known as HEVC, uses advanced coding tree units with flexible block partitioning to process images. This structural improvement enables the format to reduce file sizes by up to 50% while preserving the exact same visual quality as older standards. It readily handles the intense bandwidth requirements of ultra-high-definition media.

Codec Performance Comparison

Determining the appropriate format depends heavily on your target resolution, network bandwidth, and hardware capabilities. While standard-definition files remain manageable under older codecs, higher resolutions demand modern compression techniques.
