APPENDIX B: THE GOPRO CINEFORM CODEC 
 
Compression  
 
Video file formats use standard wrappers like AVI, QuickTime (MOV )or  MXF to ensure broad playback compatibility with numerous video 
applications. W ithin the AVI or MOV wrapper, the underlying file might be compressed (or uncompressed) using various codecs, all of which 
guarantee compatibility with a calling application thr ough OS-recognized AVI or QuickTime interfaces. The primary function of a codec is to ensure...

Codec designs are many, as are the resulting visual fidelity and CPU requirements that result from various designs. As a general rule, most 
codecs have been designed for eit her acquiring images or video inside a camera (JPEG, DV, DVCPRO, AVCHD, DNxHD) or for distribution 
(MPEG, h.264).  
 
CineForm has taken a different approach with its compression engine,  instead designing a compression subsystem specifically optimized for the 
needs of post -production, and with the...

Following are the major com ponent pieces in a CineForm compression subsystem:  
 
CineForm Wavelet Codec:  The design goals for CineForm’s codec were:  
  1.  Maintaining extremely high visual fidelity through a rigorous multi -generation post -production workflow, including high bit precision,  
yielding high signal -to -noise ratio.  
2.   Offering extremely fast performance on Intel architecture CPUs such that multiple streams can be processed in real time without the...

Visual Quality (versus HDCAM SR):  CineForm visual fidelity routinely exceeds that of the respected HDCAM SR format which is a mainstay in 
professional  production and post -production.

Visual Quality (versus HDV and DVCPRO HD):  CineForm visual fidelity substantially exceeds that of most camera compression formats such as 
HDV, DVCPRO HD, AVCHD, etc.

Active Metadata™ Technology Overview  
 
Video file formats use standard wrappers like AVI, QuickTime (MOV) or MXF to ensure broad playback compatibility with numerous video 
applications. A calling application requests frames from AVI/MOV files which are in turn decoded and presented to the calling application similar to 
the diagram below. Within the AVI or MOV wrapper, the underlying file might be compressed (or uncompressed) using various cod ecs, all of which...

GoPro Studio 2.5 User Manual 
Using its  Active  Metadata™  architecture CineForm extends traditional codec -only capability into a full -featured image development subsystem, 
including:  
 
•  Combining “active” processing of decoded images with metadata based on user -established rules. Active processing allows non-
destructive image development including color (White Balance, color matrix, 3D LUTs, etc .), 3D editorial and playback, stream -specific 
information and framing controls  
•   Metadata...

GoPro Studio 2.5 User Manual 
The following are a few examples of Active Metadata insertion into GoPro  CineForm AVI/MOV files: 
 
•  When recording to disk during live capture using a Silicon Imaging camera, white balance and 3D LUT information is w ritten into the 
CineForm RAW file.  
•   When performing disk -based conversions from R ED R3D files, white balance information from the R ED metadata fields is extracted from 
the R ED SDK and written into the CineForm file (YUV, RGB, or CineForm RAW) as...
