ARRI META EXTRACT is a free download from arri web page. Simple registration is required for access. As name says, the app will extract all metadata (collected by ALEXA camera) from QT, ArriRAW or MXF files and save CSV with all metadata, AML (Alexa Look file), CDL and LUT(cube) as separate files. LUT and CDL can be used in Resolve (or other) to recreate the look. Real fun begins when you dig into CSV file. VFX department loves it. Check it out.
