Download our free Premiere plug-in for WebM, the open movie format created by Google. WebM is the HTML-5 standard video format that relies exclusively on open source and patent-free technology. It uses the VP8 and VP9 video codecs together with the Vorbis and Opus audio codecs, wrapped up in a Matroska container. Like WebM itself, this plug-in is completely open source.

Designed with video professionals in mind, the plug-in exposes more advanced VP9 features such as 4:4:4 video sampling and 10/12-bit pixel buffers. For minimum clutter, only the most important encoding parameters have interface controls, while dozens of other settings can be adjusted using the custom arguments text field.
