Embedded Video Script for Email (2)

I have a script that allows for embedding video in an email, it mainly works on Apple devices. If someone receives an email with this script on a Mac a video will run automatically. If I receive the same email on my PC (Outlook) I will only see a graphic that will link to the video. I need the video and graphic replaced with a video and a graphic that I will provide. Also I need all other content removed so only the video / graphic that I provide will be visible in the test. See chart for before and after. This for testing so that I can demonstrate to a client that this can be done. Please be able to fully test in both environments. If you know what you are doing this is a simple project, if you don't know what you are doing please move on. Please be able to test the script in both environments.
