How to get AR sound and video to play only when the target image is detected

I am wondering how I can make it so that my AR video and audio pauses when the target image isn’t being recognized.

At the moment the video and audio continues to progress even when the target image is not on the screen, despite the video not actually being visible.

Maybe you have extended tracking switched on?

@AlwaysInBeta How do you turn it off?,So how do you switch it off?
