Optional: Check one or two sample images from the “j2k” folder, by opening them in GIMP. Set the input directory to your “tiff” folder, and the output folder to your “j2k” folder. The default options should be correct (OpenJPEG, Cinema 2K, 24 frame rate, 125Mb/s bandwidth, sRGB source, X’Y’Z’ Transform, DPX Logarithmic does not matter for tiff input, DCI Resize: None). Start the OpenDCP application and select the JPEG2000 tab. For simplicity’s sake I will make that channel appear on the centre (screen) channel in the cinema, and supply silence for the other 5 channels: ffmpeg -y -i 20120624.mp4 -acodec pcm_s24le -ar 48000 audio/audio.wav My camera records one sound channel only, and it does that badly. The frames should all be 1998×1080 pixels which corresponds to the “flat” DCI format. Mogrify -border 39x0 -bordercolor Black *.tiff The target is a vanilla 2k, JPEG2000, 2D, 24fps DCP. These frames are all the wrong size, and need tiny black bars left and right. Notice that I sneak in a frame-rate conversion here too: ffmpeg -y -i 20120624.mp4 -an -r 24 -pix_fmt rgb24 -vcodec tiff tiff/%08d.tiff The first step is to use ffmpeg to convert the video in to a series of individual frames. In this example I am using the file “20120624.mp4”. This is where you will adjust your video and audio, to make it fit within the rigid formats D-Cinema uses. Some other preparation, make yourself a work folder and some sub-folders within: mkdir DCP_ProjectĬopy your video file in to the DCP_Project folder. I am not sure if OpenDCP needs openjpeg-tools, but it’s useful to be able to sample check your JPEG2000 encoded frames. There are some other packages you will need: sudo apt-get install openjpeg-tools If you get errors about other packages not being installed, they can usually be fixed with this command: apt-get -f install Install it manually: sudo dpkg -i opendcp_0.27.1_xubuntu1210_b Visit and download the corresponding package for your system. Installing the software, and general preparation. Consider having your OS installed on an SSD, with your workspace on a big “traditional” hard disk. The sound will grow in size too, because D-Cinema does not understand compressed sound (AC3, DTS and SDDS are so ‘old hat’). You need lots of disk space, as you will be converting your video to a sequence of still frames, and doing conversions on that. An advantage of using linux for this task is that you don’t need to be worried about file-size or filename limitations, because you can save directly on to an EXT3 formatted disc, with an MBR type partition table. It should work on most, if not all, Debian-type distributions. I use Ubuntu as my “mostly-used” operating system, this is tested on version 12.10. Reasonably you could use any digital video camera if you make the appropriate adjustments to the conforming instructions. I present a work-flow to convert the output of my camera (CamSports HD-S 720p). I doubt Dave was being completely serious about the idea, but it set me thinking about the possibilities. At time I was working at a local cinema, which had recently changed all the film projectors for digital projectors. I will call this guy Dave, because that’s his name but it also has a degree of anonymity because it’s a popular name. When I started using an action camera to record my biking, someone asked me if it was possible to play the video back at the local cinema.
