Uploading videos to Muse website

Hi,

I have been joggling with work and creating an educational website using Muse. So far, it's been great and exciting and I can't wait to see this website up and running. But I have a setback concerning the instructional videos. As soon as they end youtube ads and pop-ups are a serious distraction. How can I upload the videos directly to the website without passing them through youtube? Thanks.
