"4K 30p" means the highest-bitrate 4K UHD mode at 29.97p or 30p that a V30 card can record (240 Mbps or less). If there is no 30p, we use 25p, then 24p.

Quick answer

A 128 GB card holds about 1 hr 30 min of Apple ProRes Proxy at 30p (4:2:2, 179 Mbps) on the Blackmagic Design Pocket Cinema Camera 4K. The heaviest mode, Apple ProRes RAW HQ at 30p (RAW, 1,480 Mbps), uses 666 GB per hour, so the same card lasts 10 min.

GB per hour = bitrate in Mbps x 0.45. Card times use 95% of the labelled size (formatting and file overhead). Card speed: V30 up to 240 Mbps, V60 up to 480, V90 up to 720, CFexpress above that. * Blackmagic Design's stated minimum for that format, which is stricter than the bitrate alone needs.
