Rates at 24 fps in decimal units (1 TB = 1,000 GB). RAW and intra-frame formats store a fixed size per frame, so their rate grows with the frame rate. ● marks a fixed bitrate, the same at any frame rate. Max fps: the normal maximum on the best media, in orange a special mode, in grey the limit on smaller media.
