Embed Older Powerpoint Converted Videos

I used a software program called iSpring quite a while ago to convert Powerpoint into a video format to use on a website. The files exist in my website. So obviously the iframe src no longer works for me. It builds a player that contains several playlists of Powerpoints converted into short educational movies.

The content inside my page editor uses the first url to recognize that the video should be embeded on the page: https://www.mydomain.com/aihatest/index.html

This is the page that opens up and displays the styled player to the public, I put this url in my browser and it still works to play the movies inside the player.

Will this plugin do the same thing for me or do I need to somehow convert these Powerpoints into a different type of video?
