Python script for processing OpenEXR image files to improve their usability in VFX workflows. It uses the Python bindings of the OpenImageIO library which has to be installed and accessible to the Python interpreter, e.g. using the PYTHONPATH environment variable.
The following processing operations are available:
- Auto-Crop: Shrink data window (= bounding box) to non-black pixel
- Create multi-part exr: Split channels into subimages based on their layer names
- Fix channel names: Rename channel names which could cause conflicts in Nuke (depth.z to depth.Z)
- Remove cryptomatte manifests from metadata. The manifest will be written to a sidecar file which combines the manifests for all the sequence's frames.
- Change compression mode
python src/wrapper.py /path/to/image.1001.exr will automatically detect the full image sequence and replace the images
after applying the following operations: Auto-Crop, multi-part rewrap and channel name fix. A backup of the original
files will be kept in a _BAK subfolder of the original location. For additional information, look into the --help
option.
python src/mainwindow.py launches a minimal UI which offers the same options like the CLI interface.
