Why doesn't my background video display properly in the Webflow designer with the correct height?

There could be a few reasons why your background video is not displaying properly in the Webflow designer with the correct height. Here are a few things you can check:

1. Video file format and settings: Make sure that your video file is in a supported format, such as MP4, and that it is encoded with the correct settings. In some cases, using different encoding settings or converting the video file to a different format can help resolve display issues.

2. File size and loading time: If your video file is too large, it may take longer to load, causing the video to display improperly or not at all. Consider optimizing your video file by compressing it or reducing the bitrate to ensure it loads smoothly within the designer.

3. Browser compatibility: Different web browsers may have varying support for video formats or features. Make sure you test your background video across different browsers to ensure it displays correctly. You can also check Webflow's browser compatibility guide to see if there are any known issues with the browser you are using.

4. No video controls or autoplay: By default, Webflow background videos do not have controls or autoplay enabled in the designer. This means that you won't see the video playing in the designer, but it should display properly on your published site. If you want to see the video playing in the designer, you can temporarily add controls or autoplay to the video element, but remember to remove them before publishing.

5. Screen size and breakpoints: Background videos may behave differently across different screen sizes and breakpoints in Webflow. Make sure you have set the correct height and other styling properties for each breakpoint to ensure the video displays properly at all screen sizes.

If you have checked all of these factors and are still experiencing issues with your background video, it may be helpful to provide more specific information or share your project link, so that we can take a closer look and provide more targeted assistance.
