Computer data storage Data are encoded by assigning a bit pattern to each character, digit, or multimedia object. Many standards exist for encoding (e.g., character encodings like ASCII, image encodings like JPEG, video encodings like MPEG-4).
Digital cinematography Digital cinematography has mostly shifted towards "tapeless" or "file-based" workflows. This trend has accelerated with increased capacity and reduced cost of non-linear storage solutions such as hard disk drives, optical discs, and solid-state memory. With tapeless workflows digital video is recorded as digital files onto random-access media like optical discs, hard disk drives or flash memory-based digital "magazines". These files can be easily copied to another storage device, typically to a large RAID (array of computer disks) connected to an editing system. Once data is copied from the on-set media to the storage array, they are erased and returned to the set for more shooting.
