Kneel for professional movie master to explain, thank you very much. I'm making a movie, and the camera is ARRI· Alexa. What is the format of the film?

Ai Lisha standard calculates MOV suffix, but I don't remember the encoding method. The preset sequence depends on the sharpness of your shot. Ai Lisha can vote 2K and 1080p. Since the cinema is going to shoot 2K, the sequence should be set to 2K standard (2048× 1080 2 1:9, and the intermediate film usually needs 4:2:2). After that, it can be output according to the requirements of the issuer.

PR6 doesn't know which sequence presets are available. Editing should be ok. You just need to set the output sequence yourself. You've been using Finalcut, and it's not clear how to set it up. sorry
