Colour Management
PFClean uses OpenColorIO for colour management. This affects how clips are displayed in the Cinema window (or any reference displays) and ensures accurate colour reproduction on your monitor, and can also be use to convert clips from one colour profile to another when exporting if this is desired.
In order to use OpenColorIO in PFClean, you must specify a colour profile for your clips, and a colour profile for your display. Colour conversion during export is optional and can be controlled in the File Out node.
In addition to OpenColorIO, PFClean also provides a Defect Display Booster that can be used to further enhance the Cinema display to help locate defects that are otherwise difficuly to see.
Please note that PFClean does not support import of custom LUTs, other than through the OpenColorIO configuration files. If you wish to customize OpenColorIO behaviour to introduce additional colour transforms then please see the OpenColorIO documentation for further information.
Clips
A colour profile can be assigned to each clip, specifying how colour information has been encoded in the image data. For example, after film scanning you may be importing a 10-bit DPX clip encoded with log density. In this case, you could assign the colour profile for this clip as ADX-10 to tell PFClean how the pixel data is encoded.
You can define a default colour profile for each clip bit-depth in the Clip Import preferences window. This will ensure that when you import clips, an appropriate colour space is assigned automatically.
You can also specify a colour profile for each clip individually in the Media Admin panel.
By default, clips are assigned a "raw" colour profile. This means that no information is available about how image data is encoded. In this case, no colour conversion will be applied when displaying a clip in the Cinema window or when exporting clip data after it is cleaned.
Displays
Before PFClean can adjust how a clip is displayed in the Cinema, you need to specify a colour profile for your display device. This can be done in the Displays preferences window.
You can also assign a separate colour profile to any external reference displays you may have attached to your workstation.
Export
When exporting, you can use OpenColorIO to convert from the colour profile assigned to your source media clips to another profile if you desire. This can be used to ensure exported media is encoded in a singular colour space.
The default colour space used in File Out nodes can be specified in the Export preferences window. It can also be controlled individually in each File Out node.
Cinema display view
To toggle whether OpenColorIO is used to adjust the colour of clips that are displayed in the Cinema window, click the button to toggle the display LUT on and off. This tool can also be used as a shortcut to show the Display preferences window.
If this button is disabled, OpenColorIO is not available to use either because a colour profile has not been assigned to the current clip, or a profile has not been assigned to your display device.
