Visual component "SOPSAT"

Previous page Parent topic Next page

 

The SOPSAT (SOP/Saturation) component implements a per-channel adjustment of the parameters Slope, Offset, Power (gamma correction) and Saturation. Compatible with the ASC CDL standard and Autodesk CTF standard (ASC_CDL element).

Parameters "slope", "offset" and "power" produce one-dimensional color transformations corresponding to the names of these parameters. The "saturation" parameter produces a three-dimensional color transformation, increasing or decreasing the difference between the values of the three color channels. The "saturation" parameter in the ASC CDL and Autodesk CTF standards is not per channel (applies equally to all color channels), but its functionality is extended in this component, while compatibility with the standards still remains.

It is possible to load/import parameters from ASC Color Decision List (.cdl), ASC Color Correction Collection (.ccc), ASC Color Correction (.cc), Edit Decision List (.edl) and Autodesk CTF (.ctf). To import from files, you can use the context menu of the visual part of the component, the drag-and-drop mechanism (dragging the file with the mouse on the component), or use the input port 'load file'.

Context menu

The context menu is available by right - clicking on any free area of the component.

"Processing type" group

 

"Forward" - apply formulas for direct processing.

"Reversed" - apply formulas for reverse processing.

 

"Options" group

 

"High-clamp HDR" - clipping the upper LDR boundary inside the formulas.

"Lo-clamp HDR" - clipping the lower LDR boundary inside the formulas.

"Invert power" - use the inverse of the degree in a formula that does not conform to the ASC CDL standard, but gives intuitively more predictable results.

"Lock white point" - link parameter Slope and Offset together in such a way that when you change any of them, the white point remains unchanged. This option corresponds to a small icon button component_SOPSAT_visual_fragment3 between the Slope and Offset controls. When the option is activated, the icon becomes brighter component_SOPSAT_visual_fragment4.

"Import ..." - open the file selection dialog to import parameters from a file of one of the third-party formats compatible with the ASC CDL standard. The following formats are supported: ASC Color Decision List (.cdl), ASC Color Correction Collection (.ccc), ASC Color Correction (.cc), Edit Decision List (.edl) and Autodesk CTF (.ctf).

 

"View" group

 

The visual type selection corresponds to the function of the 'control type' port.

 

component_SOPSAT_visual_fragment1

"Wheels" - the visual type of the controls in the form of color wheels. In this mode, the parameter values for each color channel are determined by the offset of the center point within the color wheel. Use the offset of the point with the Shift key pressed to change the total value for the three color channels at the same time. It is also possible to see and adjust the numerical values of the parameter for each color channel and the total value for the three channels (white numbers).

component_SOPSAT_visual_fragment2

"Columns" - the visual type of the controls in the form of vertical columns. In this mode, the parameter values for each color channel are determined by the vertical offset of the corresponding color column. Use the offset of the white color column to change the total value for the three color channels at the same time. It is also possible to see and adjust the numerical values of the parameter for each color channel and the total value for the three channels (white numbers).

 

Both visual types have the same capabilities and differ only in appearance and convenience.

Port name

Port type

Description

control type

enum

Select the visual type of the controls. Corresponds to the "View" group in the context menu of the visual part of the component.

load file

event( string FileName )

(replicable)

Load/import parameters from a file named FileName. The following file formats are currently supported: *.cdl, *.ccc, *.cc, *.edl, *.ctf.

slope

weight

(replicable)

Slope. The first replication of the port controls the overall slope. The three subsequent port replications control the slope for each individual color channel.

offset

weight

(replicable)

Offset. The first replication of the port controls the overall offset. The three subsequent port replications control the offset for each individual color channel.

power

weight

(replicable)

Power. The first replication of the port controls the overall power. The three subsequent port replications control the power for each individual color channel.

saturation

weight

(replicable)

Saturation. The first replication of the port controls the overall saturation. The three subsequent port replications control the saturation for each individual color channel.

Standard ports are not listed here because these ports and their functions are equal for all components (see " Standard ports").
