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 RAW mode:
1 Press menu and select the ‘setup’ page.
2 Navigate to ‘RAW SDI Output’ and select ‘on’.
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.
TIP: Camera raw media formats are so named because they capture raw color space
data directly from the sensor. Raw image data cannot be displayed visually, and must
be debayered or demosaiced to convert the original raw data into image data that can
then be used in an image processing pipeline like DaVinci Resolve.
Note that Blackmagic DaVinci Resolve does not support the debayering of raw data
from Blackmagic Micro Studio Camera 4K.
