If you want to show a video on your website there are multiple ways to do that. However, if you want to add the custom video using HTML5 you need to use the video tag.

Some users have reported that they get the Browser does not support this video tag error while trying to add a video to their website.

This browser issue can occur due to several reasons including incompatible video format as well as wrong syntax.

How can I add videos using HTML5 to my website?

1. Change MP4 to H264-MPEG-4 AVC format

  1. If your video is in MP4, it is possible that a browser like Chrome may not support the format anymore.
  2. This issue can only affect the Chrome browser and you might be able to play the same video on other browsers like Firefox and IE.
  3. The solution here is to change the video format using a video converter and convert the MP4 video into H264-MPEG-4 AVC. However, if that does not work you may want to add a custom piece of js code to force the Chrome show Mp4 videos without the error.
