Unity & Vuforia Augmented Label on a Can

I'm trying to make an Augmented Reality project in Unity for iOS that uses the label on a can as the target image. When Vuforia recognizes the can, I want to overlay a transparent video label so that only part of the can animates. I have the app working, and the video label looks seamless in Unity, but in the real-world, the transparent video floats slightly above the can, so it doesn't look seamless. My approach was to make a transparent cylinder the child of the target cylinder, and the transparent video is wrapped around the child cylinder that appears upon recognition. However, I feel like there must be a better approach, perhaps without using this child cylinder at all. I need a seamless look, like the video below: [login to view URL] I'm willing to pay someone to complete / fix my project, or even to give me advice on the correct approach to make this a seamless augmentation.
