What is a .ARI file?
ARI is an ARRIRAW frame from ARRI digital cinema cameras.
- Did you know
- ARRI’s Alexa cameras and ARRIRAW are a mainstay of Hollywood production.
- With plain ARRIRAW every single frame is its own .ari file, whereas the MXF-wrapped variant holds a whole clip in one file.
- ARRIRAW keeps the sensor’s Bayer data uncompressed but trims the data rate by storing it logarithmically rather than linearly.
- What Analyser reads
- Identify camera RAW edit sidecars - Apple Photos adjustments (AAE), RawTherapee (PP3), Capture One (COS), DxO PhotoLab (DOP) and Nikon NX Studio (NKSC) - reading the applied-edit recipe, plus cinema and rare camera RAW: REDCODE (R3D), Blackmagic (BRAW), Canon Cinema RAW Light (CRM), ARRIRAW (ARI), Phantom CINE and FLIR thermal (FPF).
- Depth of analysis
- .ARI is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .ARI file
- Drag a .ARI file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
