How to convert BRAW to DNG?
In 2018 Blackmagic Design company has announced a new BRAW format for their digital cinema cameras. That format is supported in Davinci Resolve software only. There is a Blackmagic BRAW SDK which allows to get processed data from BRAW. There are no means to get RAW data from BRAW to implement full image processing pipeline, starting from RAW. To fill that gap we've created braw2dng converter which is capable to output DNG / CinemaDNG series from BRAW file.
There is no exact correspondence between BRAW and DNG, because we don't have full info about BRAW format. This is closed format and there is no BRAW specification, unfortunately. Nevertheless, the difference between original BRAW and final DNG is in log curve, which user can add either during convertation or later on, while doing RAW processing on Adobe Camera Raw / Adobe Premiere or on any other software which support DNG or CinemaDNG formats. Thus, we can offer an instrument to check what could be done with BRAW and how it could be utilized with other software for raw processing.
Software Usage
braw2dng.exe
These are available options:
- -o path for output dng files (optional, BRAW file path default)
- -prefix prefix for output dng files names (optional BRAW file name default)
- -enc type of DNG encoding: u (uncompressed), l (Lossless JPEG) (optional, default uncompressed)
- -lut file with linearization curve in cvs format (optional, default built-in lut)
- -dcp file with DCP profile (optional, default built-in profile)
- -v verbose output
Examples of command line for braw2dng converter
How to convert input.braw file into dng series (out/out_000001.dng, out/out_000002.dng, etc.) with Lossless JPEG encoding
braw2dng.exe -i input.braw -o out -prefix out_ -enc l -v
The same with log curve from file lut.cvs
braw2dng.exe -i input.braw -o out -prefix out_ -enc l -lut curve.cvs -v
The same with DCP profile test.dcp
braw2dng.exe -i input.braw -o out -prefix out_ -enc l -lut curve.cvs -dcp test.dcp -v
