When shooting video footage in JP4-RAW mode the files need to be converted to a postprocessing friendly format: a DNG sequence. This software takes care of that. The resulting DNG files contain the EXIF fields of the original frames and are stored with 16 bits (linear colorspace) per channel.
movie2dng Usage: movie2dng [options] (at least one of --jp4, --jpeg, --dng or --pgm) SOURCE [DEST] This program will convert the SOURCE JP4 movie to individual frames named DEST-NNNNNN.dng, where NNNNNN will be replaced by the frame number starting at 1. Note that there is no need to specify the .dng extension on the frame name, it will be added automatically. If you want to save frames on a different directory, use something like DIRECTORY/DEST, for example. If you want to convert individual frames, pass they as SOURCE, DEST will be filled for you. [output formats] --jp4 save frames in JP4 format. --jpeg save frames in JPEG format (JP4 after deblock) format. --dng save frames in DNG format. --pgm save frames in 16 bit PGM (ASCII) format. [options] --stdout write frame data to stdout (only for single format output
and JP4 or JP46 inputs). --gui output information in a format suitable for a GUI program. --frames N convert only the N-th first frames. --shift N, Bayer shift, 0-3 (default: detect from MakerNote). --jpeg-quality N set --jpeg quality factor (1...100), default=100. -v, --version display program version information. -h, --help show this help message.
