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, which is the file I want to use as my background, and an animated_thumb.jpg to match, which is the little thumbnail I will click on to select the animated background. That said, while I could select the thumbnail, the background was still not applied.

My last hope was to rename animated.gif to animated.jpg to see if Microsoft Teams could be fooled into thinking it’s a static image, 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.
