Use of video for background removal

Hi Team, awesome app but please consider including the option to use a video as the background when using AI background removal or greenscreen.

I use Lumabooth for my 360 booth and I would like to use a video when using the background removal tool. I tried using a static photo and output was not great. I can create a video in Mp4 format and in 1080×1920 that looks like its the actual background of the beach. I plan on using the background removal tools and my beach video to make it look like people are at a different place.

I hope this is making sense but especially allow the use of a video as the background instead of a photo when using background removal tools.
