00:00:00 Introduction

00:01:22 Setup Vuforia Image Target Database

00:06:24 Import Vuforia Package for Unity 2019.3 from the Unity store

00:08:21 Setup AR camera

00:10:46 Insert image target and apply image from Vuforia Image Target Database

00:13:01 Test out image target with sample 3D game object

00:15:36 Create a Quad and scale proportionally to video footage

00:17:43 Import video footage with alpha channel, transcode and apply to Quad
(See this segment on how to prepare video footage with an alpha channel in Premiere specifically for Unity https://www.youtube.com/watch?v=4W5e6-TSpW0&t=121s)

00:20:38 Create a new material for the video playback on the Quad, two-sided and with transparency settings

00:21:55 Set properties of the Quad's videoplayer component and create an audio source component - connect audio source and videoplayer components

00:25:15 Apply VideoController.cs and VideoTrackableEventHandler.cs scripts - these were slightly modified from Vuforia's Core Samples example scenes (the core Samples package can be downloaded from the Unity store as well)

00:28:31 Setup a second image target with a 4:3 video

00:36:39 Add a still image with transparency to the second image target
