This website publishes videos in a format commonly known as "MP4" or "H.264". It is the HTML5 Internet standard for video and as such is supported by most Internet browsers and devices
MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio. It usually tied to H.264/MPEG-4 Part 10 which is a codename of a patented standard for video compression.
This standard is supported by Microsoft Windows, Apple OS X, Google Chrome, gaming consoles, smart TVs &c. plus it is natively decoded by virtually all graphic hardware including mobile devices' integrated chips.
So basically unless you are running Linux or Windows 2000 versions of Opera or Firefox on a device with graphical chipset older than 5 years, you should be fine.
Remember that out videos are not free and we allow you to download them for personal use only. For example you may transfer them to your iPad to watch later with friends but you cannot upload them to the Internet or share with people that are not your friends or family
