H.265/HEVC — ShotAI Compatibility
High-efficiency compression codec delivering 50% smaller files than H.264 at equivalent quality, ideal for 4K content.
What is H.265/HEVC?
H.265, also known as High Efficiency Video Coding (HEVC), was jointly developed by the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. Finalized in 2013, it achieves approximately 50% better data compression at the same level of video quality compared to its predecessor H.264/AVC. HEVC supports resolutions up to 8192x4320 (8K UHD) and is widely used in broadcast, streaming, and consumer recording applications. The codec employs larger coding tree units (up to 64x64 pixels) and advanced prediction modes for superior compression efficiency.
How does ShotAI handle H.265/HEVC files?
ShotAI handles H.265/HEVC files through hardware-accelerated decoding, processing 4K HEVC content efficiently even in large libraries. The indexing pipeline analyzes temporal and spatial features across each shot, understanding motion, composition, and scene semantics. HEVC metadata including HDR information (HDR10, Dolby Vision) is preserved and searchable. Search results return precise timecodes within your HEVC files, and ShotAI can generate proxy thumbnails for quick visual browsing of search results across thousands of hours of content.
When should you use H.265/HEVC?
Use H.265/HEVC when file size is a critical concern and your target audience has modern playback hardware. HEVC excels for 4K and 8K content delivery where H.264 would produce prohibitively large files. It is the standard codec for HDR content (HDR10, Dolby Vision) on streaming platforms and Ultra HD Blu-ray. Choose HEVC when archiving large volumes of high-resolution content, delivering to modern streaming platforms, or when your production cameras record in HEVC natively (common in mirrorless cameras since 2020).
