Frequently asked
questions
No. The video is loaded using the HTML5 <video> element in your browser. No data is sent to any server. Nothing is stored. The analysis happens entirely on your device.
Any format your browser supports: typically MP4 (H.264/H.265), WebM (VP8/VP9/AV1), OGG, and sometimes MOV. MKV and AVI support depends on the browser and OS codecs installed.
Browsers do not expose the video frame rate directly through the HTML5 video API. The estimate shown is calculated from requestVideoFrameCallback where supported (Chrome), otherwise it is not available.
