WebM Container Format Utilized for VP8 and VP9 Delivery. The landscape for video formats continues to change, and if you didn’t know, you’ll need to get familiar with WebM. Why? It’s because it’s one of the formats available for HTML5 video delivery. When you hear of HTML5 supported browsers, it means those browsers support WebM in addition to other HTML5 video formats. As it relates to WebM, it’s a container much like .MOV, and .MP4 are containers. The WebM container supports video codecs such as VP8 and VP9. Audio codecs that are supported within the container are Vorbis and Opus. The mime type, should you need it, is “video/webm” and the extension is .webm. So, if you’re encoding videos for web delivery, streaming delivery, or any other type of delivery your output file will be .webm. During encoding, you’ll use either the VP8 or VP9 codec in your compression preset for the video section of your encoding tool, and you’ll use Vorbis or Opus in the audio section. For additional reading, you can learn more about the WebM Container Format on the The WebM Project website. This will help you understand why the WebM Container Format is Utilized for VP8 and VP9 Delivery.
