What is a .H265 file?
H.265 (HEVC) is a high-efficiency video codec; a raw .h265 file is an unwrapped elementary stream.
- Did you know
- H.265 (HEVC) arrived in 2013, roughly doubling H.264’s efficiency at the same quality.
- Like its predecessor, H.265 was developed jointly by ITU and MPEG engineers, working together as the team known as the JCT-VC.
- H.265 earned a Primetime Emmy for engineering, credited with paving the way to 4K and 8K ultra-high-definition television.
- The codec can encode resolutions up to 8192 by 4320 pixels, and every Ultra HD Blu-ray relies on it.
- H.265 is covered by patents spread across several rival licensing pools, a fragmentation widely blamed for slowing its adoption on the web.
- What Analyser shows you
- Read the container, codec, resolution, and frame rate of MP4, MOV, MKV, AVI, and WebM video, step through frames, and extract the audio track. Raw H.264/H.265 elementary streams (.h264/.265) are remuxed to MP4 in-browser so they play too.
- Open a .H265 file
- Drag a .H265 file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
