FAQ
Is my video uploaded?
No. Only the file’s headers are read inside your browser; nothing is sent off your device.
Why does it say this browser could not play the file?
Your browser does not support one of the codecs (for example HEVC from iPhones). The details read from the headers are still shown.
Why is the duration marked “about”?
WebM files recorded by browsers and some apps do not store their length. It is then estimated from the timestamp of the last frames.
