Are mp4 files supported on a static website

[Patrick Melo]

I published a website using the instructions on the "Publishing a Website on Bitbucket Cloud" page. I added a video tag to an html page and included an mp4 file in the repo. I can view the video when I preview it on my local machine but when I publish the site, I get a 404 when I try to access the mp4 file. The documentation indicates that website supports "embedding images and other media." Are mp4 files supported? If not, what other file types are disallowed?
