Adding a Virtual Video Background, my photo library will not show videos to choose from

[Virtual_Bliss]

When I try to add a virtual video background by pushing the + sign, my photo library will not show any videos to choose from it will only show photos, which I have no problem changing still photos.

I have verified that the box is checked in settings to allow video background.

The video is 4 MB and 1080. 

I am running IOS 11.something -big sur, also using iPhone 11 pro max. I cannot choose a video from either.

I am assuming my Zoom app is up to date on both.

Please help, Thanks.
