ARRI Reference Tool | Learn & Help

ARRI Reference Tool, or ART for short, combines the functionality of the previous ARRIRAW Converter, Color Tool, and Meta Extract into a single package. You can review clips, check and extract metadata, create, extract look files, and transcode footage to a different format.

The ARRI Reference Tool allows you to render ALEXA 35/ALEXA 265 footage using our new ARRI Debayer Algorithm ADA-7 and REVEAL Color Science. It is also backwards compatible with all ALEXA and AMIRA cameras, which can be de-bayered to LogC4 and travel through REVEAL as well.

Additionally, ART supports QuickTime/ProRes or MXF/ProRes, as well as the CODEX HDE (High Density Encoding) file format. To keep your footage organized, you can create projects with bins and sequences.
