Decoder Settings

In the GoPro Studio Importer system tray application, the Decoder Settings sub-menu

gives you access to the following advanced codec settings:

• Demosaic Type

• Filter 422 to 444

• Fast Desktop Playback

Let’s discuss each of these decoder settings in more detail.

Demosaic Type

When shooting with a RAW single sensor camera like Arri D-20, RED Epic or Blackmagic

Cinema Camera, the final output quality is impacted significantly by the demosaic

algorithm, possibly as much as any compression applied. The demosaic algorithm is the

process that converts the one value per pixel of a raw bayer sensor to the more useful

three color primaries per pixel like RGB (see Wikipedia article on demosaicing

‘BiLinear Demosaic’ is a simple, fast demosaic filter suitable for real-time playback but

not suitable for final rendered output. During editorial it is helpful to use BiLinear

Demosaic because it requires the least CPU resource.

TIP: Think of the progression of Demosaic algorithms between BiLinear and CF

Advanced Detail 3 as providing additional sharpening detail in your final output.

NOTE: The Demosaic Type only affects CineForm RAW files. CineForm RAW files can

only be created from camera RAW source files, like you’ll get when recording with an Arri

D-20, RED EPIC or Blackmagic Cinema Camera (in CinemaDNG mode) or created at

record time using a Silicon Imaging SK-2K Digital Cinema Camera, KineRAW S-35 or

Cinedeck direct-to-disk recorder.
