VP9 — ShotAI Compatibility
Google's open codec for web video, widely used on YouTube, offering good quality at low bitrates.
What is VP9?
VP9 is an open and royalty-free video coding format developed by Google as the successor to VP8. It was released in 2013 and quickly became the primary codec for YouTube, which serves billions of VP9-encoded streams daily. VP9 offers compression efficiency comparable to HEVC while remaining completely royalty-free, making it attractive for web applications. The codec supports 10-bit and 12-bit color depths, 4:2:2 and 4:4:4 chroma subsampling, and resolutions up to 8K. Hardware decode support is available in most modern devices manufactured after 2015.
How does ShotAI handle VP9 files?
ShotAI processes VP9 content natively from WebM and MP4 containers, making it easy to index web-origin content, YouTube archives, and screen recordings. The indexing pipeline handles VP9 at all quality levels and resolutions up to 8K. ShotAI extracts temporal structure, visual semantics, and any WebVTT captions embedded alongside the VP9 stream. This means you can search web-captured content with the same precision as camera-original footage, finding specific moments across large collections of VP9 video.
When should you use VP9?
VP9 is an excellent choice for web video delivery when you need broad browser support without codec licensing concerns. It is particularly appropriate for YouTube uploads (YouTube re-encodes to VP9 anyway), web-based video platforms, and progressive web applications. VP9 also works well for screen recording and tutorial content where its adaptive bitrate encoding handles screen content efficiently. While AV1 is the newer option, VP9 retains broader hardware decode support on devices manufactured between 2015-2022.
