Frequently asked questions
Is my video uploaded?
No. The video is processed entirely in your browser on your own device, so it never leaves your computer or phone.
Can the rounded corners be transparent?
Standard video files cannot store transparency, so the corners are filled with the background colour you pick. Choose the colour of the page or app where the video will sit and the rounding blends right in.
How long does it take?
The clip is processed as it plays through once, so it takes roughly as long as the video itself. A one minute clip takes about one minute.
Does it keep the sound?
Yes, the original audio is included in the exported file in browsers that allow it, such as Chrome and Edge.
Which browser and format?
Chrome or Edge on a computer give the most reliable result, and the saved file is a WebM video, which all modern browsers and editors can open.
