This document specifies compositions for IMF Application #4. IMF Application #4 is a specialization of the IMF Framework, and is intended to exchange content of cinematographic work after digital postproduction either sourced from film or from digital media and can be used in a preservation framework. It specifies:

• images encoded using 16-bit XYZ color primaries and a linear transfer function;

• maximum image frame width and height of 8192 and 6224 pixels, respectively; and

• a constrained Composition structure that mimics the segmentation of movie into individual reels.

To simplify implementation, IMF Application #4 reuses constraints from IMF Application #2 whenever appropriate.
