There could be several reasons why the video in your Webflow preloader is not showing up on mobile devices. Here are a few possibilities:
1. Unsupported video format: Make sure that the video file you are using is in a mobile-friendly format. Different mobile devices have different video format support, so it's best to use a widely supported format like MP4 or WebM. Check the video specifications and conversion settings to ensure compatibility with mobile devices.
2. File size and bandwidth: Mobile devices often have slower internet connections compared to desktops, so it's important to consider the file size of your video. Large video files can take longer to load or may not load at all on mobile devices. If your video file is large, try compressing it using a tool like Handbrake or Adobe Media Encoder to reduce the file size without significant loss in quality.
3. Autoplay and mobile restrictions: Autoplaying videos on mobile devices can be controlled by the device's operating system and browser. In many cases, autoplay is disabled to save data and improve user experience. Check if the video is set to autoplay in your preloader settings. If it is, try disabling autoplay and providing a play button instead, allowing users to manually start the video.
4. Browser compatibility: Different mobile browsers may have varying levels of support for video playback. It's essential to test your website on a range of mobile devices and browsers to identify any compatibility issues. Ensure that your video's codec and encoding settings are compatible with major mobile browsers like Safari (iOS) and Chrome (Android).
5. JavaScript or CSS conflicts: If you have custom JavaScript or CSS code that interacts with the preloader or video element, there may be conflicts causing the video to not display properly on mobile devices. Review your code to ensure there are no errors or conflicts that could be affecting the video's visibility.
6. Responsive design issues: It's possible that the video element's positioning, size, or layout is causing it to be hidden or go off-screen on mobile devices. Verify that the video element is properly configured within your preloader and that its dimensions and placement are responsive, adapting to different screen sizes and orientations.
By considering these factors, you can troubleshoot and resolve the issue of your Webflow preloader video not showing up on mobile devices. It's important to test your website thoroughly on various mobile devices and browsers to ensure a seamless user experience across different platforms.
