Problem with header1 video size

Hi Guys,

I have a problem with the header video. I uploaded my own videos. Filenames video1.mp4 etc. I modified the video container module to use video1.mp4 instead of video.mp4.
Unfortunately the new video is too small in the header.
I modified the module again to use the original video (video.mp4) but it also small.
I have not modified anything more in the source code, only the filename.
What do I have to do to get the video appear in full width?
My site is www.gaben.huwww.gaben.hu

Thank you!

Hello,

Please disable WYSIWYG editor in global Joomla configuration and check if HTML code of the Video Container module is:

Thanks,

Thank you so much Milos. It helped!

The original code in wysiwyg editor was:
<div id="videobg"> </div>
<p><video id="bgvid" poster="images/video.jpg" autoplay="autoplay" loop="loop" muted="" width="300" height="150">
<source src="images/video.webm" type="video/webm" />
<source src="images/video.mp4" type="video/mp4" />
<source src="images/video.ogg" type="video/ogg" />
Your browser does not support the video tag.</video></p>

I replaced it with your code and everything is working!

Thank you again!

Hi,
It's not working for me.
I replace with your code and when I save, the video becomes white (see the image) and stay small in the preview. 

Hello,

You must disable the TinyMCE editor in Global Configuration, paste the code, and save. Otherwise, the TinyMCE will cut off some parts of the HTML code. Also, you can install a more advanced editor, such as JCE.

It's working!
Thank you very much!
