Is special videotape used to produce or duplicate 3D video?

Not at all! Standard video tape is used with standard NTSC video recorders; HD tape is used with High Def recorders. DigiBeta, DV Cam, DV Pro, HDCam, etc. The difference is with the cameras and the way the video is recorded. Playback can include standard: VHS, Mini-DV, DVD, Blu-Ray etc, or directly from hard drives and other digital media.
