videowebm

Videowebm is a term used in open-source and industry discussions to describe a workflow or concept that centers on using the WebM container for delivering video on the web. It is not an official standard and there is no formal specification named videowebm. The idea is to combine WebM, an open, royalty-free container based on Matroska, with modern video codecs such as VP9 or AV1 and audio codecs like Opus or Vorbis to enable efficient, browser-friendly web playback.

In practice, videowebm refers to producing and serving video assets that are encoded in WebM format for web delivery, leveraging the container’s support for multiple tracks, including video, audio, and subtitles. Proponents argue that WebM-based assets align well with HTML5 video elements, benefit from broad browser support, and integrate with open tooling and streaming pipelines. Some workflows emphasize metadata handling and interoperability with existing WebM tooling for editing and playback.

Adoption of the term is uneven: while WebM itself is widely supported in major browsers, the specific label videowebm is informal and varies by project. There is no single governing body or specification that defines videowebm beyond the underlying WebM format and codecs. For most practitioners, the concept serves as a shorthand for WebM-based web video workflows rather than a distinct, codified format.
