Can you try with video embed code which you can get from youtube as well. Try once may work.

Hi All,

I have created a branding in Office 365. Now I want to add video in the background of my master page.

How should I achieve It. the <Video></Video> is not working. It is giving error to me.

Any option how to add videos in background of master page in Office 365?

Thanks in Advance.

Hi,

From your description, my understanding is that you want to use video tag in your Office 365.

You should check the video type in your issue, video tag only support mp4 file which you could refer to this article:http://www.w3schools.com/tags/tag_video.asp.

In addition, you could refer to these articles:
