Today, video content reigns supreme. From streaming movies and TV shows to attending virtual meetings, video is an integral part of our lives. To deliver this content seamlessly, efficient video compression is essential. Enter VP9, an open-source video codec that has revolutionized how we experience video.What is VP9 Codec?VP9 is an open-source video codec developed by Google after their acquisition of On2Technologies in Feb 2010. This was the second codec, after VP8, to be released, and it became available to the masses in June 2013. It's designed to deliver high-quality video at lower bit rates than other codecs. This makes it particularly efficient for streaming video over the internet. In terms of usage, the largest distributor of VP9-codec content was YouTube. Later, in 2016, Netflix, too, announced the use of VP9 for their platform. Since then, many new use cases have emerged where VP9 has proven to be a viable solution.

Context, VP9 is twice as effective as H.264, and uses only half the data to stream 4K content without compromising on quality.VP9 vs H.265When talking about VP9 vs H.265, it is important to note that there are many technical similarities between the two. Even the primary goal of both these codecs is the same - to compress video files into half the bitrate to stream HD video and provide better compression techniques for 4K video to become more approachable for people with regular internet bandwidths. That said, the biggest difference between these two is that VP9 is an open-source codec and can be used by anyone, whereas H.265 requires a license to be purchased before using. In terms of usage and efficiency, these two codecs are by and large comparable.AV1 vs VP9The primary difference between AV1 and VP9 is that while AV1 is worthwhile only for videos with views in the mid-to-high millions, VP9 is worth considering for even videos with view counts in excess of a few thousand. Further, since VP9 is free and enjoys widespread use, it is going to be a much more viable choice in the near future. Video Codecs availability by browserWhat is the Future of VP9 Codec?The future of the VP9 codec looks promising as it continues to be a widely used standard for high-quality video streaming, particularly in 4K resolution. Its efficiency and support for advanced features, like adaptive bitrate and HDR, ensure it remains relevant. However, as newer codecs like AV1 gain traction with even better compression and performance, VP9 may gradually see reduced adoption. Despite this, VP9 will likely continue to be supported and used in various applications for the foreseeable future.ConclusionIn conclusion, the VP9 codec has proved to be extremely useful for streaming 4K videos seamlessly, even with limited bandwidth.
