web-video
From the author
Encode a video for the web with a bundled ffmpeg script: AV1, HEVC, and H.264 MP4s plus a JPEG poster for ordinary video, or VP9 WebM and HEVC with alpha plus a PNG poster for transparent video, picked from the source automatically. Use when the user wants to optimize, compress, or convert a video, screencast, screen recording, or animated cover for a website, blog, docs, or landing page; speed up or downscale a recording; get AV1, HEVC, or WebM versions; or ship a transparent video that plays in both Safari and Chrome. Do NOT use for editing beyond speed and size, adaptive streaming (HLS, DASH), or video hosted on YouTube or Vimeo.
