.avi not an option for rendering

I am using the latest version of Unreal.

This is my first render in Unreal for a school assignment. I need to render in AVI but that doesn’t seem to even be an option.

All of the articles and tutorials I can find say that it should automatically want to render as a movie, but mine automatically renders .jpgs and I can’t find anything in the setting to render it out as .avi.
