How big are CineForm files?
CineForm Intermediate files are encoded using a variable bitrate algorithm, so file sizes vary based on scene complexity, image resolution, frame rate, and chosen compression quality. But the following ranges apply reasonably well: HDV: For 1440 x 1080 60i HDV material, you can expect a range of arount 10 – 14 MBytes/sec, or around 40GB/hour. In comparison, 1280 x 720 24p material will be about half that size. These files are larger than are generated by in-camera MPEG or AVCHD codecs to enable more “headroom” for manipulating the files in post, offering significantly improved visual fidelity within multi-generation workflows. HD: 1920 x 1080 10-bit 24p streams usually range from about 15MB/sec to 20MB/sec, or about 60GB/hour. 2K: 2K file sizes are comparably larger than HD files because of increased spatial resolution. Also, if your 2K files originated as film scans they will have a lot of grain in them. It is for this reason CineForm created our two “”””Filmscan”””” modes – to preser
