New Template - HTML Content-BGVideo-Homepage

New to this, so please bear with me.

I recently purchased a new Opencart template (this is my second) and I'm having issues finding where to replace a video embedded into the homepage.

When I check out the modules, I can easily edit the overlying text, but there is not an option to replace the video. It is named HTML Content>BGVideo-Homepage. I found the video file, but need to know where I can redirect the new video. I'm relatively new to all of this, but I have searched high and dry for any connection to this video. I know it has to be somewhere, just not sure where.

Here is the link to the unedited site (as purchased). About 1/2 way down there is a video embedded into the background with text.

Not sure how common it is to add login credentials, but here are some access credentials:

Any help here would be greatly appreciated.
