What are the new technologies in Avatar 2?

Avatar, a dreamy and magnificent Pandora planet created by 3D virtual image photography and motion capture technology, almost redefined the "subtle and immersive" viewing experience, which not only triggered a phenomenal viewing craze around the world, but also dominated the global box office list with nearly $3 billion, and even won many awards including Oscar for best photography, best artistic direction and best visual effects.

According to Cameron, Avatar 2 is "difficult to produce" for two reasons, one is that the script is difficult to write, and the other is that it is technically difficult. The former led him to dismiss almost all the screenwriters in his previous work and asked the team to continue writing the script and present a brand-new story to the audience, instead of the "dog tail continues mink" in his previous work. As for the challenge of technology, it is Cameron's consistent self-demand for decades.

"Avatar" has left us memories far beyond box office data or countless awards. Remember that winter when there was a long queue at the entrance of Peace Cinema in the cold wind to buy tickets? Crowds can stroll in raffles city along hankou road, Yunnan Middle Road, Fuzhou Road and Tibet Middle Road. Even so, because it had the only IMAX giant screen in Shanghai at that time, 90% of the performances of Avatar were sold out within 24 hours after the invoice was issued, leaving only about 2,000 tickets in the first three rows in the IMAX hall. Looking through the historical photos, the cinema also temporarily issued a "ticket number" that was "invalid the next day".

The plot of Avatar 2 follows the previous film, and sam worthington, the actor of Jack, has all returned, but the film will present a brand-new landform different from the previous film, from the rainforest dominated by darkness to the magnificent ocean, which will bring strong visual impact. It is said that Cameron specially prepared a motion capture system for underwater shooting to restore the real scene of underwater diving, and the crew also specially prepared a huge water tank with 900,000 gallons of seawater to simulate ocean currents to the greatest extent.

The actors in Avatar 2 have been trained, got diving certificates, and even held their breath for a few minutes every time they filmed a scene. Kate winslet once said in an interview: "The longest time I hold my breath is 7 minutes 14 seconds, which is really crazy." Cameron also confidently said: "We won't use any scuba to shoot, so the materials of the pictures we shot are quite beautiful and the main points of motion capture are perfect."
