ASP.NET prevent videos & images from being downloaded

Question

Hi.

I'm a recent college graduate and need help in preventing my original videos & images from being downloaded in my site. I also want to allow for the videos to do playback & images to be viewed.

I'm using Visual studio 2017 c# web development.

I researched the DRM & EME video player markets but I don't trust using them because they're cloud compatible. I implemented the code to where i can prevent right click save but, browsers still have a "save page as" feature in them. I'm aware of the video download programs that are existent to where people copy the url and paste them to the programs to get the videos to their hard drive.

Is their a way or code the page with videos url cannot be downloaded?
Is their also a way that screen-record programs cannot get the videos as well?

I don't want to take the path of a watermark over the videos but it's looking like that's my only option. I was wondering if anyone can please help with advise. Some code to where when i can commercialize the site and it's effect in the prevention of my content from being taken.

Thank you for all who read and reply.
