I know I can use Vuforia + Unity to superimpose objects onto target images when viewed through the camera...however is it possible to do this based on prerecorded video? Essentially, I have recorded video of a scene with a target image in it. I'd like to have video playback in Unity, but superimpose objects onto the target objects within the video that's playing...so basically, the basic vuforia functionality yet performed on a prerecorded movie rather than camera input. Any advice??
