J2k player5/25/2023 Above this the frames will start dropping. XYZ Color Space Bit Rate The maximum bit rate at which it the files will be transcoded is 250 Mbit/s at 24 Frames/s.Pixel Depth : 12bits per pixel(12x3=36 bits in total ) Color space.ğull Container (2048 x 1080 for a 2K and 4096 x 2160 for a 4K) : Aspect Ratio : 1.9 :1 MPEG2(MXF Interop).Ē3.976 and 24 fps for 1920 × 1080 or a 2K screening Frame Size and Aspect ratios: JPEG2000(SMPTE).Ē4 fps for a 2K stereoscopic screening MPEG2(MXF INTEROP) As discussed earlier also, this format is not much in use ,however the frame rate for these are :.Ē4 and 48 fps for a 2K stereoscopic JPEG2000(MXF INTERLOP STANDARD).Ē4, 25, and 30 fps for a 4K screening.Lets us now get an understanding of Frames used : Frame Rates : JPEG2000(SMPTE STANDARD) They will surely provide the details of the DCP for their Cinema Projection Screen. The standard should be checked with the Cinema Theater for screening. There are two industry standard followed : a) SMPTE b) MXF INTERLOP Now, at most places, the SMPTE standard is accepted. We will not get into the details of MPEG2 format specification as this is out of the scope of this article. However, it is no longer complaint with DCI(Digital Cinema Initiatives) specifications, but is still acceptable in some theaters as video format for screening. These Six Files mentioned below are part of the DCP format : 1) Video/Image MXF File 2)Ěudio MXF File 3)Ěsset Map File 4)Ĝomposition Playlist File(CPL) 5) Packing List File(PKL) 6) Volume Index File Let us now discuss some technical specification for these files to get a more detailed understanding of the DCP package : 1) Video/Image MXF File The Video/Image file is basically a J2C more commonly know as J2K(JPEG2000) image sequence which is wrapped in MXF file container.In certain theater, MPEG2 format technology is still being used, wrapped in the MXF container. Since the cost involved in broadcasting is pretty high using the UFO format, J2k DCP format become the only ideal and the best solution for small scale players in the market.

J2k conversion is the last step in the post-production process. This is an image compression format required for screening of the Ad Films/Ad Commercial in Theater. What is the J2k Format? J2k refers to JPEG2000. ![]() A DCP package consists of additional files along with the audio and video files which acts as supporting file and which run concurrently with the audio and video MXF files to provide information as to how this file will be running from beginning to end. The images file consist of the image -JPEG2000 file format and audio- 24-bit Linear PCM channel. These files can also be encrypted to avoid unauthorized access to the data. It is a container file similar to MOV or AVI.
