showing an iMovie on a TV screen using a USB port
I have created an 11 minute iMovie. I want to show it on a TV screen that has a USB port and is capable of showing DVD"s. How do I get the iMovie on a flash drive? We have a macOS, sequoia 16.6.1. It's been suggested to save t as an mp4. I have no idea what that is.
