This is standard countdown leader, counting down 8 to 3 and then with one frame of 2, at which point there is a single frame beep on the sound track. It is used at the beginning of a film for the lab to line up sound (using the beep) and later for the projectionist to know when to turn on the lamp and hopefully not miss the opening of the film. A common mistake is to count the footage from the 2, but actually frame zero is the one right before the first 8, a single frame with the words Picture Start. Academy Leader is sometimes also known as S.M.P.T.E. leader.thepolliofolioglossaryofcinematographyterms
In projection, the aperture cutout, designed as specified by the American Academy of Motion Picture Arts and Sciences that provides for a screen-image aspect ratio of approximately 1.37:1; also called sound aperture.
In 35mm this is the full frame exposed by the camera, with an aspect ratio of 1.33. When the film is projected there is a mask in the projector’s gate to change the aspect ratio to 1.85 or 1.66, cropping the top and bottom of the image. Older films were not shot to be masked and should be projected without a mask. The Academy Aperture is sometimes called the Full Academy Aperture.
