Frequently Asked Questions
Why does trimming take as long as the clip itself?
The trim captures the selected range in real time: the clip plays while frames are drawn to a canvas and recorded. A ten-second cut therefore takes about ten seconds.
Which formats does the export support?
The recorder outputs WebM (VP9 or VP8 with Opus audio where supported), which every modern browser plays. Convert to MP4 with a separate tool if you specifically need that container.
Is the original video quality preserved?
The export bitrate is selectable up to 8 Mbps. Higher bitrates keep more detail but produce bigger files; the source resolution is preserved by the canvas capture.
Is my video uploaded anywhere?
No. Playback, canvas capture and recording all run locally in your browser through MediaRecorder, and nothing is stored or sent anywhere.
