Exporting to MP4 or WEBM

Hi all,

I am trying to make a very specific sized video for a website header.  The header is currently working fine with any MP4 or WEBM but I am trying to get my HTML working with the standard Premiere Pro WMV output. This doesn't seem to work.

Could anybody advise me either of either the correct HTML or how I can export to an MP4 or WEBM file?

Also, whilst I am here. I suppose it could be true that WMV's are too resources heavy to use as website backgrounds. Would that be correct? In which case I really do need to export to one of the other formats.

Thanks for any advice.

What no edit button??

Sorry, I meant to add my current HTML which is....

<video class="video-fluid" autoplay loop muted>
<source src="images/videos/vid-intro.mp4" type="video/mp4" />
</video>

Naturally I've tried all the obvious rewording to get a WMV showing.

Thanks again.

OK I am sorry everybody, yes the answer was on the forum so I apologise for duplicating. Is there really no edit or delete button though?
