The CinemaDNG file format is designed to store high-resolution video streams in camera raw format and typically adds less than 1 KB overhead per image. CinemaDNG files typically require half the storage space of corresponding DPX files. Each video frame is independently encoded using the DNG (Digital Negative) image format. The video stream is stored either as a picture track in an MXF (Material Exchange Format) file or as a sequence of individual frame files.
CinemaDNG uses fully-documented, vendor-neutral, standard formats for video and imaging – DNG, TIFF/EP, and MXF. The format is unencrypted and free from intellectual property encumbrances or license requirements. Several SDKs are available for each of the components of the format.
The CinemaDNG format allows vendors to add functionality on set or in post, for example, by extending the decoder SDKs with additional image processing or metadata processing.
