Reverse Engineering the GoPro Cineform codec. Following the fine traditions of great codec reverse engineers it has now become the norm to write-up the trials and.

Missing codec: CineForm High Definition video files CFHD. Windows Media Player can t play the file or can t play either the audio or video portion of the file.

Support decoding the CineForm codec. Reported by: dericed: Owned by: Priority: wish: tell them you want cineform cfhd decoding support in the ffmpeg project.

The GoPro CineForm codec is optimized for encoding video content with 4K and higher resolution, including support for smart rendering.

CineForm Intermediate is a proprietary video codec developed for CineForm Inc by David Taylor, David Newman and Brian Schunck. On March 30, 2011, the company was acquired by GoPro which in particular wanted to use the 3D film capabilities of the CineForm 444 Codec for its 3D HERO System.

The press release in the GoPro acquisition noted that CineForm s codec has been used in several major movies including Slumdog Millionaire. 1 2

The CineForm Intermediate Codec was originally designed 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 when. 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 reversible wavelet compression kernel, with non-linear quantizer to achieve higher compression. Compression data-rates typically range from 10:1 to 3.5:1, based on quality settings. There is also an uncompressed mode for RAW files.

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 larger file sizes for greater decode and encode performance. Currently when., CineForm is only available as software implementations on Mac OS and Microsoft Windows platforms, however a Linux SDK is available.

There is also the DPC format also known as DPX-C, which is a DPX file header with or without an uncompressed DPX image part that is just containing a thumbnail. Then a compressed CineForm sample is attached to that file, containing the wavelet compressed image in full size. The format is being used in post production when CineForm files need to be rendered by render farms. There are tools to split up CineForm AVI or MOV files into DPC file sequences, and vice versa, to reassemble CineForm MOV and AVI files from DPC sequences. These steps just copy data and do not reencode the images, thus are extremely fast and do not cause iterative recompression artefacts.

There are plugins for Eyeon Fusion and The Foundry Nuke compositing systems to read and write the CineForm DPC, AVI and MOV files natively. These plugins have been developed by Magna Mana Production.

CineForm is very stable to iterative recompression.

Compared to JPEG2000, CineForm has a slightly higher data rate at similar PSNRs peak signal to noise ratios with the benefit of being up to 7 times faster to encode/decode on the same hardware.

According to a GoPro press release, 3 SMPTE has standardized the CineForm codec as the SMPTE ST 2073 VC-5 video compression standard. 4
