Volumize 2D Video

Hello!

I am trying to take a 2D MP4 video and move it around in 3D space but, as the video is moving, it leaves behind a 'snapshot' of the previous frame. I like to think of it as similar to particle trailing, but the trail is a video.

Is there a good way to do this? I'm pretty new to Unity so any solutions/advice would be greatly appreciated!!! Thank you!

Currently, I have a Quad with a RenderTexture of the video attached to it and it can move in 3D space.

I haven't found any documentation on how to use a 'Trail' but replace the trail with a video, but that was one of my ideas for this.
