A new kid on the block: Codex HDE.
HDE stands for High Density Encoding. It is an encoding technique that is optimized for Bayer pattern images. ARRIRAW images encoded with HDE are approximately 60% of the original size. HDE encoding is completely lossless - when an HDE file is decoded, it is a bit-for-bit perfect match to the original file.
For more information, please visit the ARRIRAW FAQ and filter for HDE in the pull-down
