Academy award for best cinematography's selection rules

Generally speaking, the participating films (including documentaries) must be longer than 40 minutes except short films, and must be shot with 35 mm or 70 mm film, and the number of frames must be 24 frames per second or 48 frames per second. The resolution of digital movies should be no less than 1280×720. Producers of films must fill in the registration form before the election deadline, including the list of producers, the names of cinemas showing in Los Angeles, and the release and next release dates.

The first step in Oscar selection is nomination. Each branch of the college lists the film titles that are eligible to participate in the selection (that is, the actor branch chooses the performance award, the director branch chooses the director award, and the photographer branch chooses the photography award) and submits them to the studios for review. At the same time, each branch shall formulate detailed rules for the selection of professional awards and report them to the College Council for approval. Then, the members of each club choose the five films or individuals with the most votes by secret ballot, and the list is usually announced one month before the award ceremony. The earliest Oscars did not limit the number of nominations, resulting in

In several sessions, the total number of films nominated for best picture exceeded ten. Starting from 1944, the academy limits each award to five nominations at most (starting from 20 10, the nomination for best film is expanded to 10), and for each human award, it is determined according to the number of films involved, with no restrictions. Therefore, based on this rule, for many filmmakers, getting an Oscar nomination is the highest honor recognized by peers in this profession. After the nomination list is drawn, it is the final award voting. Each member under the name of the college can only cast two votes. In addition to the fixed vote for the best film, another vote is for awards related to his major (for example, members of the directors' committee can only select the best director award, while four types of performance awards can only be selected by actors). The whole voting process is similar to the democratic election of one person, one vote, and the whole process adopts closed voting. The billing and statistics work is carried out by the third-party accounting firm appointed by the college (PricewaterhouseCoopers has been in charge for more than 70 years), and the final result, as the most exciting suspense, is sealed in an envelope under the notarization of a notary for the announcement of the award ceremony.
