Side-by-side comparison

Your browser only plays the surface of an MKV.

Drop an MKV with multiple audio tracks, embedded subtitles, or chapters. See exactly what the native <video> tag silently ignores — and what <movi-player> surfaces from the same bytes.

Drop your own video file or click to pick

MKV / HEVC / AV1 / HDR / multi-audio / subs — anything your <video> tag normally chokes on. The file never leaves your device. By default we load Sintel (Blender open movie, ~1.1 GB) so you have something to look at immediately.

Mirrors MoviPlayer's play / pause / seek to the native <video> so both panes stay locked on the same frame. Click again to release.
