Its been sometime coming, since I have been experimenting and planning this for sometime now, but its finally nicely on its way. The whole concept was born from the desire to create my own DCP Packages for testing of stereo footage at our local Digital Cinema. It is effectively a Gui based front end to quite a few command line tools available online for the creation of DCP files.
This first phase automates the entire process of converting an image sequence to the cinema jpeg 2000 format. It can handle 2K stereoscopic and 2K monoscopic flat formats (not scope yet) and exports the image sequence ready for DCP Packaging. Currently the conversion from sRGB .tif takes roughly 1min 30secs for 24 stereo frames (effectively 1sec of film). When stereoscopic is enabled it converts each image stream independently considerably speeding up the conversion time. Originally these conversions took nearly 6mins per 24frames when run as a single process.
As it stands the converter takes care of a few XYZ colour space conversions, outputting a 12bit XYZ Image following the Cinema 2K specifications. I am quite interested in colour space so hope to expand this area in the future.
The roadmap for the next phase includes, Implementation of 4K Cinema standards under monoscopic conversion, MXF Wrapping for both Video & Audio, and the creation of the DCP Package xml files. Ultimately I hope it to be a full DCP conversion and packaging tool!
I am interested to know what other options may be needed, what colour space’s do most people work in, would the loading of a custom LUT be of value, should I investigate input formats such as DPX and EXR?
