IMAX 3D

This segment shows how IMAX 3D experience is created. Two independent key components featured in this video: IMAX = huge projection screen, large film format, powerful multi-channel sound system. 3D = stereoscopic effects. Note that most IMAX theaters popping up in recent years use IMAX digital projectors. No film is involved, hence portions of this video do not apply to those new theaters. Digital IMAX movies are transported by multi-giga byte computer hard disks. Many new IMAX screens are about 40 feet tall which are only half the height of the 80 feet tall screen depicted in this video. Traditional IMAX theatre is usually a 8 story tall building you can spot from blocks away. For example, in San Francisco Bay Area, the only tall IMAX screens are in the SONY Metreon building in San Francisco and Hacienda crossing 21 theater in Dublin, CA. The few dozens new IMAX theaters are all small screen substitutes. Interesting statistics on this video. When Harry Potter IMAX 3D experience came out in July 2007, the daily views on this video peaked at 4600 views on one day and the increased views lasted for about 2 weeks. When Avatar came out in Dec 2009, the daily views only peaked at 1200 views, but the increased views lasted for a month and are still coming in as of this writing.
