REC/CALC

Data confidence. MEASURED means the data rate was back-calculated from the manufacturer's own published record-time or capacity figures. For the Sony BURANO these come from Sony's official record-time table on a 960 GB CFexpress Type B VPG400 card; for ARRI from ARRI's published record capacities on the 2 TB Compact Drive, which imply 13.06 bits per pixel on the ALEXA 35 and 12.10 on the ALEXA Mini LF — matching ARRI's stated 13-bit and 12-bit ARRIRAW. VERIFIED means media bindings and codec restrictions were checked against manufacturer documentation while the data rate is a nominal spec figure. EST. means the rate is calculated or industry-reference. Sony's Data Calculator on SonyCine and ARRI's Data Rate Calculator remain authoritative for those systems. Capacities listed are the sizes commonly available across card manufacturers for each format; not every size exists from every brand.
