CineForm Intermediate

CineForm Intermediate is proprietary video codec developed for CineForm Inc [1] by David Newman and Brian Schunck.

CineForm History

The CineForm Intermediate Codec was originally designed back in 2002 for compressed Digital Intermediate workflows for film or television applications using HD or higher resolution media. The CineForm media is most commonly wrapped within AVI or MOV files types, using the 'CFHD' FOURCC code for all compressed media types.

Current implementations support image formatting for 10-bit 4:2:2 YUV, 12-bit 4:4:4 RGB and RGBA, and 12-bit CFA Bayer filter RAW compression (as used with the Silicon Imaging SI-2K camera.)

All compression is based on an integer revisible wavelet compression kernel, with non-linear quantizer to achieve higher compression. Compression date-rates typically range from 10:1 through 3.5:1, based on user driven quality settings.

The codec uses a constant quality design, such that the data rate will vary based on the source image data. It shares some properties with other wavelet codecs, like JPEG 2000, yet it trades off some compression efficiency (little larger files sizes) of more decode and encode performance. Currently only a software implementation on Mac and Windows platforms.
