Frequently asked questions

Does the video keep its quality and sound?

Yes. Resolution, frame rate and length stay the same, the original audio is copied unchanged and the video is encoded at the same or a slightly higher bitrate.

How long does it take?

Usually seconds. An 8-second 720p Veo clip takes about 3 seconds on a normal computer.

Is my video uploaded?

No. The video is processed by your own browser and never leaves your device.

Which browsers work?

The latest Chrome, Edge and Safari. Firefox works too but may save the result as WebM.

Can it remove moving objects from a video?

The brush is made for things that stay in place, such as logos, text and stamps. Moving objects are not supported.
