"Bullet Time" covers 21 events
According to the Olympic Broadcasting Service (hereinafter referred to as OBS), the Paris Olympics uses China's Alibaba Cloud AI-enhanced Brand new broadcast technology - multi-camera playback system. This system gives the broadcast a visual effect like a science fiction movie, presenting the audience with special effects such as enhanced slow motion and time freeze, which is called "bullet time".
It is reported that OBS has deployed this system in 14 competition venues including the Champ de Mars, Place de la Concorde, etc., covering seven-a-side rugby, badminton, gymnastics and track and field, basketball, beach volleyball, table tennis, wrestling, tennis, and judo , break dancing, BMX freestyle and skateboarding and other 21 events.
"Bullet Time" has attracted global attention
On July 29, the Chinese women's volleyball team faced the defending champion US women's volleyball team, winning 3:2 and getting off to a good start. When the score reached 9:9 in the first game, in the live broadcast, Zhang Changning, the No. 9 player of the Chinese team, who was leaping high in front of the net, suddenly stopped, and then the camera began to circle around her, showing the smashing action without blind spots. At the end of the round, the stillness was lifted, Zhang Changning spiked the ball and scored, and the audience burst into applause.
A netizen left a message on social media: "Zhang Changning is so cool. This technology is really cool. I want to see more and look forward to the 'Bullet Time' highlights."
In the women's basketball group match on July 30, the US team Led by two-time WNBA MVP Aja Wilson, the team defeated Japan 102-76, with "bullet time" appearing many times in the broadcast. The official account of the USA Basketball team retweeted Wilson's "Bullet Time" video of "No look pass" on international social platforms and commented, "No eyes needed."
Through the "bullet time" special effect, the audience can clearly see that when Wilson passes the ball, his eyes look to one side to confuse the opponent, and at the same time, he accurately passes the ball through the defense from the other side to his teammates to complete the assist. Let the audience intuitively feel the charm of this sport and the superb level of athletes.
