Summary
When creating/editing project preferences, you can change the bit depth and the graphics process bit depth.
Depending on the settings chosen, the render time and quality can vary.
This article presents the different choices and their values.

Bit Depths
The following are the available bit depths for stored images. The higher the bit depth, the bigger the frames will be.
8-bit (integer, RGB stored as 24 bits)
10-bit (integer, RGB stored as 32 bits)
12-bit (integer, RGB stored as packed, using a proprietary format: 36 bits total)
12-bit u (integer, RGB stored as unpacked: 48 bits total)
Graphic Processing
This is the way the graphic card is going to process the frames. The higher the bit depth, the longer the render will take.
8-bit (8-bit integer precision per colour component)
16-bit fp AKA "half float" (16-bit floating point precision per colour component)

Notes
In some modules, using 16-bit floating-point processing (vs integer) will allow you to have a broader color range and go beyond the 0.0 (black) and 1.0 (white) limits.
With integer bit depths (8/10/12), all colors will be clamped to their usual range.
If you want to display a 10bit broadcast output from the NVidia-SDI, you need to use the "Graphic Processing" 16fp bit depth, otherwise the signal will be shown as 8bit. |
