IBC’s Big Screen theater, a fixture of the RAI Conference Center in Amsterdam, features digital projection, 7.1 surround sound and seats 1,750 people. Not a bad place to watch a 3D film. Attendees of the IBC 2009 Awards Ceremony, held in the theater last year, got a look at an extended 16-minute excerpt from Avatar prior to its release. This year, IBC will open the theater to all attendees for two full-length screenings of Avatar and Toy Story 3. The Avatar screening on Monday, September 13, at 6:30 p.m. is actually a  “Special Edition” featuring eight new minutes of previously cut content. Toy Story 3 will be shown in full Dolby Surround 7.1 on Saturday, September 11, at 6:30 pm. Both shows are open to all on a first-come-first-serve basis. If you’ll be at the show and want to attend, get in line early.

Show organizers are also planning a special set of 3D-themed conference sessions on Saturday, September 11, and Monday, September 13. As we heard in late July, Avatar‘s editor, Stephen Rivkin, will kick off IBC’s new Digital Media Training Workshops, presented by Future Media Concepts, with a keynote address about his experiences working with Cameron and the creative challenges the film presented in the edit suite. The speech and workshops begin on Saturday at 10:30 am in the Emerald Room on the convention center’s first floor. Additional sessions on 3D sport, highlighting the FIFA World Cup, are also scheduled in a separate venue on Saturday. Another keynote on 3D for live broadcast , featuring 3ality’s Steve Schklair, will take place on Monday.

Makers of stereoscopic tools will also be using the show to help train attendees in 3D production. 3ality Digital, a sponsor of IBC’s Big Screen experience, will introduce a new lightweight and wireless stereoscopic production rigs at the show this year. The company will also promote its 3D IQ training series, which aims to teach on-set “S3D” shooting techniques in a series of master classes at its Burbank offices and at other studio locations.

Other IBC Big Screen supporters will screen behind-the-scenes profiles of their 3D customers on the set and in the studio. P+S Technik, for example, plans a one-hour “show and tell” of high-profile users of its Standard and Freestyle stereoscopic rigs. Check it out at 4:45 – 5:45 on Saturday before the Toy Story 3 show.
