<P> Broadly, two workflow paradigms are used for data acquisition and storage in digital cinematography . </P> <P> With video - tape - based workflow, video is recorded to tape on set . This video is then ingested into a computer running non-linear editing software, using a deck . Upon ingestion, a digital video stream from tape is converted to computer files . These files can be edited directly or converted to an intermediate format for editing . Then video is output in its final format, possibly to a film recorder for theatrical exhibition, or back to video tape for broadcast use . Original video tapes are kept as an archival medium . The files generated by the non-linear editing application contain the information necessary to retrieve footage from the proper tapes, should the footage stored on the computer's hard disk be lost . With increasing convenience of file - based workflows, the tape - based workflows have become marginal in recent years . </P> <P> 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 . </P> <P> Such RAID arrays, both of "managed" (for example, SANs and NASs) and "unmanaged" (for example, JBoDs on a single computer workstation), are necessary due to the throughput required for real - time (320 MB / s for 2K @ 24fps) or near - real - time playback in post-production, compared to throughput available from a single, yet fast, hard disk drive . Such requirements are often termed as "on - line" storage . Post-production not requiring real - time playback performances (typically for lettering, subtitling, versioning and other similar visual effects) can be migrated to slightly slower RAID stores . </P>
