Dear dpizzle
Thank you for your suggestion.(and sorry for late reply)
I could do what I wanted to do.
I unchecked "Play On Awake" and edited 「DefaultTrackableEventHandler」 in the ImageTarget.
I could do when I find the marker then video plays and when marker loose then video pause(stop).
I attach my script below.

Hi,
Based on the error the class TrackableBehaviour does not recognize the parameter "NOT_Found". I checked which parameters the class accepts and NOT_FOUND is not on the list.
Link to class with Status parameters https://library.vuforia.com/content/vuforia-library/en/reference/unity/classVuforia_1_1TrackableBehaviour.html
I believe by changing the value to NO_POSE you should get the expected behavior, the error will definitely be solved.
Thank you.
