Chrona

Local video frame extractor

Open editor

Convert a WebM clip into PNG frames.

WebM is common for browser recordings and web delivery. Chrona can inspect it locally when the browser supports its VP8, VP9, or AV1 video track.

Open the local editor

Check the codec as well as the container

A WebM file can contain different codecs. Current browsers often handle VP8 and VP9, with AV1 support varying by device and browser. Chrona reports a decoder problem instead of uploading the file for conversion.

Sample or keep every frame

Use original rate for animation and motion review. Choose fixed FPS when you need a smaller, evenly spaced sequence for a visual reference or dataset.
