WebM for Premiere

With the introduction of the WebM project, users who relied on web video format for their processing were able to access and develop high-quality video data, in an open-source environment. With reliance on the HTML-5 standard and open-source and patent-free technology, WebM is built around a principle that defines the file container structure, video, and audio formats.

The main compression algorithms that are employed are based on the VP8 and VP9 video codecs and the audio streams are compressed using the Vorbis and Opus audio codecs. The wrapping is provided through the Matroska container.

WebM for Premiere is a specialized plug-in for Adobe Premiere Pro and Media Encoder, which targets the WebM video format, and it is also open-source. The main highlights of the plugin are that it offers more advanced functionality for the VP9 video codec, such as 4:4:4 sampling, as well as 10 or 12-bit pixel buffers.

The main working interface incorporates just the essential encoding parameter controls, but users have access to a much wider range of adjustability, through the included text field input. Using it, one can enter custom arguments, call for particular commands, adjust parameters and define custom characteristics for processing and the output data.
