[type of data: composed data (literal) and composed data—controlled terms (non-literal typed)]
For moving image works, indicate the intended aspect ratio for the image as it was originally released (the intended presentation format). This should be distinguished from the aspect ratio of the image captured or printed on the film prior to masking for projection. Use a ratio to indicate the intended aspect ratio, e.g., 1.33:1, 1.85:1, or 2.35:1.
In addition, use the most specific of the following terms to describe the original image format of a moving image, if known:
- standard silent aperture
- standard sound aperture
