x264 is a best-in-class MPEG-4/AVC encoder that's used for a variety of uses such as web video, Blu-ray disc and broadcast television encoding. It supports 10-bit 4:2:2 as required by DPP. A 10-bit build of x264 is required to make AVC-Intra files. x264 will warn you if you encode AVC-Intra using an 8-bit build. x264 can be downloaded from: http://download.videolan.org/pub/x264/binaries/ (choose the latest and remember to get a 10-bit build) or better still, compiled from scratch.
x264.exe input.file --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --tune psnr --fps 25/1 --interlaced --force-cfr --avcintra-class 100 --output-csp i422 -o out.h264
(If you get errors about avcintra-class it means your x264 is too old)
BMXlib is a library from BBC R&D that is designed to manipulate mxf files. It was used to create the reference DPP files. http://sourceforge.net/projects/bmxlib/
raw2bmx.exe -y 09:58:00:00 -t as11op1a -o out.mxf --avci100_1080i out.h264 --wave in.wav --wave in.wav
In this instance two input stereo wave files are used, which is the minimum DPP requirement. These wave files have a bit-depth of 24-bits per sample.
3: DPP Metadata Application
Alas, you say, the DPP Metadata Application isn't Open Source! This is true, however the metadata application itself uses BMXlib and it's also possible to add the metadata manually using BMXlib but it's rather tedious. Import the output mxf into the application and it should be possible to fill in each tab and pass validation
And after transwrapping, you have a DPP compliant file. Want to know more? Use the chat box in the bottom right to ask more questions.
