Can I import a video with a alpha channel?

Hi there I’m doing a virtual art gallery for a client, but they also want sculptures as a part of the experience. But since they will be importing their own assets and since they don’t want to use the photogrammetry process I was thinking of using a video that records the sculpture on a turntable with a green screen that is used to create a alpha channel for the video. So far I’ve set up a 3d test model and a version of it as a image texture below (to show the client a comparison), but the question is can I replace that image texture with a video and it’s alpha channel? If not got any other ideas on what I could do?

Thanks in advance.

In the end I went with using a video with a green screen and used UE4’s Chroma Key Material…
