WebM — ShotAI Compatibility
Open web media format designed for efficient streaming, typically containing VP9 or AV1 video with Opus audio.
What is WebM?
WebM is an open media file format designed for the web, developed by Google and first released in 2010. The container format is based on the Matroska (.mkv) container and typically contains VP8, VP9, or AV1 video paired with Vorbis or Opus audio. WebM was created specifically for efficient streaming over HTTP, with a focus on low computational footprint for both encoding and decoding. The format is natively supported by all major web browsers (Chrome, Firefox, Edge, Safari) and is commonly used for HTML5 video elements, web advertising, and user-generated content platforms.
How does ShotAI handle WebM files?
ShotAI ingests WebM files containing VP8, VP9, or AV1 video streams along with associated Vorbis or Opus audio. The system handles web-origin content including screen recordings, live stream archives, and user-generated video. During indexing, ShotAI analyzes visual content at shot boundaries while simultaneously transcribing audio for combined search. WebM content is treated with the same AI-powered analysis as any other format, meaning you can search web captures, recorded presentations, and streaming archives with natural language queries.
When should you use WebM?
WebM is purpose-built for web delivery and is the ideal choice for HTML5 video elements, web applications, and browser-based media players. Use WebM when building web applications that need embedded video, when you want a royalty-free format for web distribution, or when targeting platforms that prefer open formats. WebM is particularly well-suited for short-form web content, animated backgrounds, product demos on websites, and any video that will be served directly via HTML5 video tags rather than through a streaming platform.
