Eliminate the dark loading screen flash effect from HTML5 videos

I've been working on a website for an online game that I'm currently playing. I've added an HTML5 video in the header section, but there's a brief flash of black screen while it loads, specifically in Chrome (no issues in Internet Explorer). Is there a way to eliminate this flash or perhaps change it to white to match the background? You can see what I'm talking about by visiting . If you compare how the video loads in IE and Chrome, you'll notice the difference. Alternatively, is there a better approach to integrating this video without compromising quality like using an animated GIF?

Thank you!

The section dedicated to Posters on this blog post highlights the following:

"If a poster image is not specified, the browser may simply display a black box that fills the dimensions of the video element."

You might think that adding a background-color of white to the video element would solve this issue, but unfortunately, it won't work. However, you can easily fix it by adding a simple white poster image like this:

<video width="320" height="240" autoplay="" poster="http://dummyimage.com/320x240/ffffff/fff" >
  <source src="http://testingfortagpro.meximas.com/movie2.mp4" type="video/mp4">
</video>

If you want to prevent blinking in Firefox, consider using a transparent gif poster:

poster="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7"

In my experience, simply adding the gif poster wasn't sufficient to eliminate the blinking issue. I found that hiding the video until it begins playing resolved the problem:

<video autoplay style="visibility:hidden;" onplay="var s=this;setTimeout(function(){s.style.visibility='visible';},100);">

You may need to adjust the timeout delay based on your specific needs. In cases where autoplay is not enabled, I had to increase the delay to 400 ms.

I encountered a similar issue and resolved it by utilizing CSS display:none to conceal the video element until its onLoadedData event indicated that it had completed loading. Subsequently, upon receiving this event notification, I changed the display property to block.

By implementing this solution, I successfully eliminated the occurrence of the black flash.

Even though I added a poster attribute to the video tag, the black box continued to flash when the page was refreshed. However, by utilizing the hide function on the 'beforeunload' event, I successfully eliminated the black flash.

$(window).on('beforeunload', function() {
   $("video").hide();
});
