Good to know
Is my video uploaded?
No. The file is opened by your browser and is not sent to Rascal or a third party.
Does this show codec and frame rate?
Not yet. Browser APIs reliably expose duration and dimensions, so this tool only reports values it can verify.
Which video formats work?
MP4 and WebM are the safest choices. MOV and M4V work when your browser supports the file's video codec.
