Integrating videos into your sliders can be a powerful way to engage visitors, but getting them to play automatically and behave as expected can sometimes be tricky. Based on common community discussions, this guide covers the most frequent video-related issues in Smart Slider 3 and how to resolve them.

Why Won't My Video Autoplay?

This is perhaps the most common question. Modern browsers, especially Chrome, have strict policies that prevent videos with sound from autoplaying without a user interaction first. This is a browser-level restriction, not a limitation of the slider itself.

Solution: To comply with these policies, you must mute your video. This can be done in the settings of your video layer (YouTube or Vimeo). Locate the 'Volume' option and set it to 'Mute'. This significantly increases the chance of the video autoplaying successfully. It's also important to ensure the video is set as the Slide Background Video and not just added as a linked content layer, as the background video feature is designed for this specific purpose.

Removing Unwanted Controls, Branding, and Links

Users often want a clean, seamless video experience without YouTube or Vimeo branding, related videos, or clickable links that open the video in a full-screen player.

Solution: It's important to understand that YouTube and Vimeo have terms of service that require certain branding elements to remain visible on embedded videos. Completely removing all controls and logos is typically not allowed by these platforms. For a completely clean video, the most effective solution is to self-host an MP4 video file and use it as a background video. Note that using MP4 background videos is a feature available in the Pro version of Smart Slider 3.

To remove a clickable link that opens the video in a new tab, ensure you have not placed the video URL in the 'Link' field of a content layer. Instead, the video URL should be placed directly in the 'Slide Background Video' field.

Dealing with Playback Delays and Loading Issues

You might experience a delay before a Vimeo video starts playing, or see a loading spinner indefinitely.

Solution for Vimeo Delay: A common cause for a 2-3 second delay on Vimeo videos is the use of a cover image. For optimization, the slider doesn't load the Vimeo iframe code until the cover image is clicked. To make the video start immediately, avoid using a cover image. The iframe will then load with the page, eliminating the delay.

Solution for Loading Spinner: An indefinite loading spinner is usually a sign of an issue on the video platform's end (YouTube or Vimeo) or a connectivity problem, as the slider itself does not control this loading state. Testing the video in different browsers and networks can help identify if it's a local issue.

Controlling When the Video Plays and Stops

A frequent goal is to have the slider's autoplay pause while a video is playing and to have videos stop when they are scrolled out of view.

Pausing Slider Autoplay: To make the slider wait for a layer video to finish before advancing, navigate to the slider's main Autoplay settings and ensure the 'Stop autoplay on - Media started' option is enabled.

Pausing on Scroll: By default, the slider is designed to pause videos when they are not visible on the screen to save resources. If you need a video to continue playing even when scrolled out of view, locate the 'Pause on Scroll' option within your YouTube or Vimeo layer's settings and set it to 'Never'.

GDPR and Privacy Considerations

If your site needs to comply with privacy regulations like GDPR, you may be concerned about cookies set by YouTube and Vimeo.

Solution: Smart Slider 3 offers a 'YouTube and Vimeo privacy enhanced mode' in its Global Settings. However, it's crucial to understand that even with this mode enabled and using youtube-nocookie.com URLs, these platforms may still set certain essential cookies (like VISITOR_INFO1_LIVE). The privacy-enhanced mode primarily disables personalized tracking cookies. For full compliance, you should consult the official documentation from YouTube and Vimeo regarding their embedded player cookies.

By understanding these common pitfalls and their solutions, you can effectively troubleshoot and create the engaging video slider experience you want for your website.
