Video metadata viewer
See exactly what is inside a video: codecs, size, frame rate, tracks, and the tags that identify it.
Video Tools
See which video formats this browser can play, and whether your file will play elsewhere.
Your files and text are processed on your own device, inside this page. Nothing is uploaded to Dubinity or stored, and closing the tab discards it. How privacy works
Two separate answers. The support table is this browser's own answer, asked of it directly rather than looked up in a list someone wrote down. The file check reads your video's real container and codecs on this device and says, plainly, how widely that combination tends to play - and what to convert it to if the answer is "not very".

Swap a clip between MP4, WebM and MOV, or strip the audio track out as MP3 or WAV.
Re-encode a clip to H.264 MP4 with sensible defaults, so it plays anywhere at a fraction of the size.
Turn a clip into an animated GIF using two-pass palette generation, which keeps colours sharp and avoids banding.
Cut a video down to the part you want, without uploading it anywhere.
Record your screen, a window or a browser tab, with your microphone if you want it.
