Why is my HTML5 video not showing up when I try to embed it using the Webflow embed HTML widget, even though the video plays fine when I paste the URL into a browser? I have followed the coding guides correctly.

It can be frustrating when an HTML5 video doesn't display as expected in Webflow. Here's how to troubleshoot the issue:

​

1. Check Video URL

• Ensure the URL is correct: Triple-check that the video URL is correct, direct, and publicly accessible.
• Video format compatibility: The video should be in a format supported by all browsers such as MP4, WebM, or Ogg.

​

2. Review Embed Code

• Correct HTML syntax: Verify the syntax within your embed code is correct. Example: <video controls><source src="your-video-url.mp4" type="video/mp4"></video>.
• MIME type match: Ensure that the type attribute in <source> matches the MIME type (e.g., video/mp4).

​

3. Address Cross-Origin Issues

• CORS settings: If the video is hosted on a different domain, ensure that its server is configured to allow cross-origin resource sharing (CORS).

​

4. Browser Compatibility

• Test on multiple browsers: Check if the issue persists across different browsers to rule out browser-specific problems.
• Enable browser console: Use DevTools to check for any errors related to media playback.

​

5. Webflow Embed Settings

• No conflicting elements: Ensure that other elements or styles on the page are not conflicting with the video display.
• Embed widget correctly: Make sure the code is placed within a Webflow Embed element, and that the embed widget is functional.

Summary

To resolve an HTML5 video display issue in Webflow, check the video URL and format, ensure correct HTML syntax, address potential cross-origin issues, test across browsers, and verify there are no embedding conflicts.
