RAW
SDI
Output
If you would like to perform your own debayering of the image data from Blackmagic Micro
Studio Camera 4K, you can use the ‘RAW’ mode to output bayered sensor data over the
SDI output.
This mode packs raw data into the pixels of a regular UltraHD 422 frame size, to enable
transmission through a standard SDI output.
The data can be recorded as an uncompressed QuickTime movie using a disk recorder capable
of uncompressed 10-bit recording, for example a Blackmagic HyperDeck Studio Pro.
Enabling

mode:

Resolution
and
Bit
Depth
The resolution of the RAW frame is 3872 pixels x 2192 lines, which includes a border that
surrounds the image data. Most users discard this border after debayering, as it can contain
image artifacts on the outer edges.
The RAW data at pixel number 16 inside the horizontal and vertical corners will therefore
correspond with the corner of the Ultra HD frame when the camera is outputting 3840 x 2160 in
the non RAW mode. The bit depth of each pixel will be 12 bits.
