Can I use a YouTube video as a wallpaper?

Not directly. Download the video to a supported format first, then import it into Wallper.

For copyright and technical reasons Wallper does not stream directly from YouTube or other online services. If you own the rights to a video that’s hosted online, download it as an MP4 using your preferred tool and import the file into Wallper.

For best results, aim for a 4K source at a steady frame rate (24, 30 or 60 fps). Wallper automatically trims silent audio and normalizes color space during import.
