Beyoncé opened the 2022 Oscars with a “Be Alive” performance, which was nominated for Best Original Song for the movie “King Richard” but recorded its version on the Compton tennis courts before the gala.
Beyonce did not want to risk and leave the spectacular and elaborate musical number with which she opened the ceremony of the 94th Oscar Awards in the hands of possible unforeseen events.
And it is that his performance, as has now been revealed by a director of ABC, the chain that broadcast the event, was recorded before the celebration of the gala. 
The decision has been defended by Rob Mills, also a representative of the multinational Disney, owner of the channel, as another example of professionalism and perfectionism on the part of the music diva. “It was pre-recorded. As you can see, Beyoncé had a great vision for this song, and I don’t think anyone wanted a chance to influence the future of performance, “Mills told Billboard Magazine.
The sister’s Venus and Serena Williams introduced the American artist from the stage of the Dolby Theater in Los Angeles since the song “Be Alive” that Beyoncé performed on the tennis courts of Compton, California, where the two were formed tennis stars, belongs to the soundtrack of “King Richard.”
This film narrates the sporting origins of the Williamses. It focuses on the ambition and determination with which their father Richard directed their careers, without forgetting the demanding and even authoritarian character he exhibited. 
The role of Richard above in the film earned Will Smith his first Oscar award. However, the actor ended up starring in endless headlines for less pleasant reasons, as he surprised the guests and viewers who followed the ceremony by slapping Chris Rock after making a joke about his wife. Source
