CinemaDNG is the result of an Adobe-led initiative to define an
industry-wide open file format for digital cinema files.

samples:

DNG, TIFF, TIFF/EP, MXF, XMP. Each image is encoded using the DNG image
format. The image stream can be stored in one of two formats: either as
video essence in an MXF file, or as a sequence of image files in a file
directory.

you might want to look at the mxf and dpx demuxers.
