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 written into the
CineForm RAW file.
• When performing disk-based conversions from RED R3D files, white balance information from the RED metadata fields is extracted from
the RED SDK and written into the CineForm file (YUV, RGB, or CineForm RAW) as Active Metadata.
• When a stereo (3D) CineForm file is created, the second stream is stored as Active Metadata, plus other optional fields.
GoPro CineForm Studio allows for:
• Modifying Active Metadata. Active Metadata created at source file origination always resides inside the file and can never be modified.
Modifications to Active Metadata are stored in CineForm’s Active Metadata Database file. GoPro CineForm Studio allows a user to revert
to the source metadata regardless of future metadata modifications within the Studio application.
• Setting Global Playback controls. You can define for playback that all, none or only a portion of the Active Metadata should be applied
upon decode. A couple examples of when this is useful:
o During editorial with CineForm files, the editor may have used Active Metadata color to establish look-intent. But when rendering
from a CineForm file to DPX files a choice might be made to only apply white balance and not apply the color look-intent used
during editorial with Active Metadata.
o During 3D playback, global playback controls allow the user to choose whether to play a CineForm stereo file as 2D (either Left
eye or Right eye), or as one of four different 3D presentation formats (side-by-side, over-under, field interlace or anaglyph).
• Defining the rules for applying CineForm’s numerous demosaic algorithms for CineForm RAW content during playback or rendering.
When a calling application requests playback of a CineForm file, the Active Metadata processor computes the final output based on user-defined
global playback rules, plus individual Active Metadata fields.
