The WebM VP 9 codec is a royalty free codec and is open source.
If you’ve not heard of this codec before, it was developed by Google as an answer to the HEVC/H265 codec.
VP9 is the video codec that operates along with the Opus audio codec in a WebM container.
The VP9 Codec’s Goal
The aim of the VP9 codec was to reduce the video bitrate by at least 50% compared to the VP8 codec.
It also seeks to also rival the compression quality of HEVC.
HTML5 Support for VP9
A standout advantage of the WebM VP9 codec is it is supported in most HTML5 web browsers.
Web browsers such as Chrome, Opera and Firefox and Microsoft Edge support the direct playback of a video fileembedded with the WebM VP9 codec.
The exceptions are Apple’s Safari and Microsoft’s Internet Explorer.
Android Support for VP9
Android started supporting the VP9 codec beginning from Android 4.4 KitKat version.
Final VP Codec
VP9 is the final VP codec developed by Google. Google did announce the intention to develop the VP10 codec. However, it later incorporated ot into the AV1 (AO Media Video 1) project.
Media Player Support
The VP9 has native support in such media players as VLC, Media Player Classic (MPC-HC) and even Android TV boxes.
Does Netflix Use the WebM VP9 Codec?
Netflix tested the VP9 codec and HEVC (H265) and found that both had equal compression capacities.
But VP9 emerged as a better compressor for videos with larger resolution than HD
Netflix encodes its videos in both the H264 and VP9 codecs. When you download a show into your Android device it is encoded with the VP9 codec.
That’s understandable as the VP9 codec isn’t widely supported in the industry yet.
Tests by Handjack have shown that the Chrome browser can play video without stutter over a laptop at a resolution of 4096 x 4096 at 60fps encoded with the VP9 codec.
On the other hand, a video encoded with HEVC- H265 with a resolution of 3840 x 2160 would not play over their laptop.
In short, the VP9 codec offers compression quality similar to HEVC but much smoother playback can be enjoyed over mobile devices and computer.
WEBM VP9 Codec and YouTube
YouTube uses the VP9 codec. That’s understandable as the codec is the creation of Google.
If you encode your video with the VP9 codec, you’ll reduce your file size significantly, at least by 50% compared to if you do it with H264. This will save you on upload time if you have a long video.
Free VP9 Encoders
If you’ve decided to embrace VP9 to save on file size and video bitrate and don’t have a video converter that supports VP9, here are some free options for you.
The Pazera WebM Converter encodes your video using the VP9 codec with a Vorbis audio stream.
It accepts the input of many video formats, including AVI, QT and ASF, but the supported output is only VP8 or VP9.
Alternatively, you could use the popular, open source video transcoder, HandBrake.
