"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

ARI to CG4 Conversion: FAQ

What are ARI files?

ARI represents a RAW image format associated with an ARRI digital video camera. Such files most likely contain stills from a video clip and can be processed using digital post-production software. ARRI is one of the biggest providers of film equipment in the world and its cameras were used to film some of the most popular motion pictures in international cinema.
