How to set an animated background in Microsoft Teams without third-party software

You probably already tried to add a new background with a .mp4 or .gif extension, but soon realized that Microsoft Teams will only allow you to select from .jpg, .jpeg, .png, and .bmp files.

I thought to myself: what if I uploaded a .mp4 or .gif to wherever Microsoft Teams stores those custom uploaded backgrounds?

A quick search lead me to ~/Library/Application Support/Microsoft/Teams/Backgrounds. I copied an animated.gif and an animated_thumb.jpg to match, and while I could select the thumbnail, the background was not applied.

My last hope was to rename animated.gif to animated.jpg, and low and behold, after selecting the thumbnail, the GIF actually played in the background.

So if you have a MP4, just convert it to a GIF, because MP4s won’t work.
