web development – Automatic creation of web pages by downloading a video

I do not know how to put these words together for google.
So, I have a paid site, I use the zilla file to download paid video content to my password protected area on a web hosting server.
I wanted to download it and then put a thumbnail or give on the normal public html page with the size of the video that is in the protected area.
So, it makes it easier for me instead of adding the images by hand.
Just download a video to create the page or add new videos to one of the pages already created.
