Goal: encode IMF App2(E) compatible MXF and create and edit IMPs.
State: Basic creation and editing works. Files pass Netflix' photon.
Note: For decoding IMF files, see imf-frameserver
The development of imflib so far has been sponsored 100% by ODMEDIA. I am looking currently for more sponsors. Please get in touch.
- create and edit App2E compatible IMPs from your video files (RGB, YUV444, YUV422, 10 & 12bit, FullRange)
- passes Netflix' photon
- supports multiple CPLs, virtual tracks etc.
This library consists of two programs. imfenc and imfgui.
imfenc is a command line application that lets you encode arbitrary videos to IMF App2E compatible MXF files containing JPEG2000 and PCM.
imfgui is a Qt4 app GUI application that allows you to create App2E compatible IMPs. It's not very flexible at the moment but gets the job done.
- The programs are a WIP. Therefore they might be clumsy to use :-) Please open an issue on Github if you need a certain feature implemented or if you encounter bugs.
- Audio MXF creation not yet finished. Needs to be done manually using custom as-02-wrap build from this repo (see manual.pdf)

Run sh imfenc.sh
markus@ubuntu:~/projects/imflib$ sh imfenc.sh --help
Allowed Options:
-h [ --help ] show help
-i [ --in ] arg input file
-o [ --out ] arg directory where output files shall be
stored
-t [ --temp_dir ] arg directory for temporary files, defaults
to output directory
-f [ --force ] overwrite output files
-b [ --broadcast_profile ] arg (=1) broadcast profile (1-7)
-d [ --bitdepth ] arg (=10) target video bit depth (8, 10 or 12)
-r [ --sample_rate ] arg (=48000) target audio samplerate (48000 or 96000)
-p [ --pixel_fmt ] arg (=RGB444) pixel format of output. (YUV444, YUV422,
RGB444)
--use_tiles use tiles (only broadcast profile 6 and
7) [default: false]
--nomux dont mux the encoded files into MXF
--experimental_extract_audio extracts pcm
--threads arg number of threads for jpeg2000 encoding
--full_range arg (=0) full range color space (rgb essence
only), else SMPTE 274M-2008 constraints
are used
Example for mov file:
sh imfenc.sh -i <YOUR_FILE>.mov -o ~/<OUTPUT_DIR> -b 6 -p RGB444 --full_range 1 --threads 16 --experimental_extract_audio
Start the gui with sh imfgui.sh
