We have many clients who want HTML 5 background videos on their landing pages. Apart from the fact that these videos do not play on iPhones they cause some serious LCP issues.

We tried setting the display setting for the container & the video to NONE for mobiles but when I run a performance report it still loads that container and the video (see attached).

My question is how we prevent this video from loading for all mobile devices.

There is a way to make background videos play on Iphones, if your clients think it's worth the delayed loading speed

Thank you for the reply, I have sent you my email address. I have an iPhone.

Sofar only one client requested specifically to display the video on phones, it works great for Android but not on iPhone. Your suggestion would be appreciated for this client.

We try and avoid videos for all mobiles, Google penalizes your listing when searching on a phone and your page has a huge payload.

The size of the video shown in the screenshot from https://pagespeed.web.dev/ (LCP.jpg) could be reduced. It is, of course, a matter of judgement as to how much compression leaves a tolerable quality. I guess that, at least for narrow viewports, one could reduce substantially.

To show what I mean, I've temporarily put a reduction of that video to 1MB at https://fc7777.coffeecup.com/homepage-video-reduced.zip . I have no way of testing whether it would help on iPhones.

I looked at it with my iPhone, and only the waterfall to the left in the first picture looked a bit weird. But the same happens when viewed on my PC.

I agree, but it seems to me to do so also at the full size at https://www.theguys.co.za/ .

Thank you for this, but sadly the quality of the video viewing it on a mobile device is extremely poor, it's even worse on a desktop monitor.

Sadly, when using a background video, you have no option to load a smaller video or even another file on narrow viewports. If it were possible, it would solve my problem.

It can be done using a duplicate of the Background Video Element (BVE) with a different video and using display:block and display:none to switch them at a breakpoint. Having a duplicate makes only a trivial difference to the project size. Apart from having the different video, one is usually duplicating only a container and some text elements.

Because it seems that one cannot mess with the class names in BVE's, it's necessary to use IDs for them and to switch the settings using Apply Styles 'To this element id only' as in the example at https://fc7777.coffeecup.com/bve-switch.rsd .

I exported Frank's file and tested it with my iPhone. None of the video files will play. On my iPad they do.
Frank may have heard me saying that my iPhone is very old, version 6. Well, last week I took the plunge and upgraded to iPhone 13, so it has all the bells and whistles of a new one ;)
