How can I solve the issue of autoplay not working on a Vimeo video within a video modal in Webflow?

If you're experiencing issues with autoplay not working on a Vimeo video within a video modal in Webflow, there are a few potential solutions you can try:

1. Verify Vimeo's autopause settings: By default, Vimeo videos pause when they're not in the active viewport to improve page loading performance. To ensure autoplay works within a video modal, you need to disable the autopause feature in your Vimeo video settings. To do this, go to your Vimeo video settings, navigate to the "Player" tab, and uncheck the "Autopause" option.

2. Use custom code: Create a custom code embed within your Webflow project to override Vimeo's default behavior. This requires a little bit of coding knowledge, but it gives you more control over the video player's settings. For example, you can use the Vimeo Player API to programmatically control auto-play, loop, and other playback options. You can find more details and code examples in the Vimeo API documentation.

3. Check Webflow's interactions: If you're using Webflow's built-in interactions to trigger the video modal, make sure you've correctly set up the interaction to start playing the video when the modal opens. Check that the interaction is triggering the correct element and that the autoplay option is enabled within the interaction settings.

4. Test in different browsers: Autoplay behavior can vary across different browsers and their policies regarding autoplay videos. Test your video modal in multiple browsers to ensure compatibility. Keep in mind that different browsers may have different autoplay policies, such as requiring the video to be muted or considering user interactions before autoplaying.

5. Consider CDN limitations: If you're hosting your site on a Content Delivery Network (CDN), such as Webflow's asset hosting or services like Cloudflare, be aware that some CDNs may impose additional restrictions on autoplay, especially for videos hosted externally on platforms like Vimeo. Contact your CDN provider or refer to their documentation to understand any limitations on autoplay videos.

Remember to test your changes thoroughly across different devices and browsers to confirm that autoplay is working as expected. If you're still experiencing issues, reaching out to Webflow support or the Webflow community forum can be valuable sources of assistance.
