4K Video Codecs: What Codec Your 4K Video is Encoded With?

You know, in terms of video formats and codecs, 4K resolutions (3840×2160 pixels) contain four times more pixels than current popular Full HD resolutions (1920×1080), which means that there is lots more data per frame to transmit to your audience. Luckily, there are codecs that are up to the challenge of tackling 4K resolutions and beyond.

HEVC/H.265 - the choice 4K codec for video on demand

HEVC, also known as H.265 and MPEG-H Part 2, is the successor to the current generation of H.264/AVC codec. It fully capable of encoding and decoding 4K resolution videos. And you can find that it comes with most 4K TVs and computers monitors. In H.265 vs H.264 comparison, if you encode with H.265 codec, it will consumes up to 8x -10x more computing power than H.264, being twice high efficiency but in larger size. Video of demand services like Netflix, Hulu, YouTube etc. encode their video content available ahead of time before making it available for viewer. Thus it can afford the additional computing power of course. Therefore, usually the 4K streaming videos from YouTube, Netflix are wrapped with HEVC 4K video.

H.264/AVC - still capable for 4K codec video, but not so effective

At the very beginning that 4K videos emerged, 4K videos are encoded with H.264 codec. And till now, H.264/AVC is still perfectly capable of processing 4K resolution videos. Whereas comparing HEVC, H.264 4K video codec is less efficient, with half data compression ratio and twice larger video size at the same 4K video quality.

VP9 - the current most popular of 4K video codecs for the web

HEVC vs VP9, HEVC goes with the current 4K encoded videos on demand, while VP9 is definitely more ubiquitous royalty-free codec that has gains popularity in web with gradually shift from Flash to HTML5 technology. It's widely implemented in web browsers like Google Chrome, Opera, Mozilla Firefox etc. Besides, you can also find VP9 4K videos on YouTube as well, which offers VP9 video at all resolutions.

AV1 - the future of 4K codec for the web

AOMedia Video 1 (AV1) is an open royalty-free video coding format designed for video transmissions over the Internet. It can be used together with the audio format Opus in a future version of the WebM format for HTML5 web video and WebRTC. Moreover, AV1 improves bitrate effciency by 30% over HEVC and VP9 and is designed for higher resolutions like 4K videos. With the benefits of AOMedia Video 1, it's a fair assumption that AV1 will see rapid adoption by major browsers (Mozilla, Microsoft, Google), content distributors (Netflix, Amazon, YouTube), and device manufacturers.
