ARRI Reference Tool (ART)

The tool for ARRIRAW processing

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

The ARRI Reference Tool allows you to render ALEXA 35/ALEXA 35 Xtreme or ALEXA 265 footage using our 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. The ARRI Reference Tool is available as GUI and CMD version. 

With our ARRI Reference Tool Viewer (ART Viewer) we are now introducing a completely re-designed version of our ARRI Reference Tool (ART) with updated Graphical User Interface (GUI). The current version only has viewing capabilities and we will add additional features e.g. render functionality step by step.
