If you are experiencing a thin black line appearing in the mobile view of your page with a background video in the hero section, there are a few potential causes and solutions to consider:

Check for overflow issues: This issue could be caused by an overflow problem, where the dimensions of the video or its container are not properly set. Make sure that the video element and its container are correctly sized and that there is no overflow occurring.
Verify video aspect ratio: It's possible that the aspect ratio of the video is not matching the aspect ratio of the container. This can result in black bars appearing around the video, including the thin black line you mentioned. Ensure that the video has the appropriate aspect ratio to fit the container properly.
Consider video compression: If the video file is too large, it may take longer to load, causing the black line to briefly appear. Try compressing the video using appropriate video compression techniques or tools to reduce file size without sacrificing too much quality.
Check for conflicting styling or positioning: Conflicts between different CSS styles or positioning properties can sometimes cause unexpected visual glitches. Inspect the relevant CSS properties of the video, its container, and any surrounding elements to ensure there are no conflicting styles or positioning causing the issue.
Test on different devices: It's important to test the page on various mobile devices and screen sizes to see if the issue is consistent across them all. If you find that the black line only appears on certain devices, it may be due to specific browser or device rendering issues. In such cases, you may want to explore browser-specific CSS fixes or utilize specific CSS media queries to target those devices and apply necessary adjustments.

By addressing these potential causes, you should be able to troubleshoot and resolve the issue of the thin black line appearing in the mobile view of your page with a background video in the hero section.
