Change Intensities

Top  Previous  Next

The Change Intensities command can be used to modify the intensities of effect events in a selected area of a sequence in a wide variety of ways.  You can access it through the Change Intensities submenu on the right-click context menu.  The submenu has three menu items: Quick, Recent, and Detailed.  Although it is listed last in the menu, we will discuss Detailed first:

 

Detailed

 

Selecting this will open up a tool window which can be used to set the various options determining how Change Intensities will behave:

The Change Intensites "Detailed" tool window

 

In the tool window, there are three main options: Operation, Percent, and Channel Types.  There is also an Apply button to apply the Change Intensities tool to the sequence.

 

Operation and Percent

 

The Operation dropdown list is used to select among several different behaviors of Change Intensities.  The Percent textbox is used to specify a percentage, the exact meaning of which depends upon which operation is selected.  The operations are:

 

Cap
Floor
Increase
Reduce
Scale

 

Cap

 

The Cap operation imposes a maximum upon the intensities in the selected area.  For example, using a percent of 80, any intensities above 80% of the effect type's maximum will be reduced to 80%, and any intensities that are already at or below 80% will be left unchanged.

 

Note that most effect types (intensity, twinkle, shimmer) have maximum possible values of 100, so for those effect types this means the same thing as "any intensity above 80 will be reduced to 80".  However, the DMX intensity effect type has a maximum value of 255, not 100, so for it, capping with a percent of 80 means capping at a value of 204 (i.e. 80% of 255).

 

Floor

 

The Floor operation imposes a minimum upon the intensities in the selected area.  For example, using a percent of 80, any intensities below 80% of the effect type's maximum will be increased to 80% of the maximum, and any intensities that are already at or above 80% will be left unchanged.

 

Note that most effect types (intensity, twinkle, shimmer) have maximum possible values of 100, so for those effect types this means the same thing as "any intensity below 80 will be increased to 80".  However, DMX intensity effect type has a maximum value of 255, not 100, so for it, imposing a floor with a percent of 80 means imposing a floor at a value of 204 (i.e. 80% of 255).

 

Increase

 

The Increase operation increases all intensities in the selected area by the specified percent of the effect type's maximum value.  For example, using a percent of 20, a fade up from 0 to 60 will be changed to a fade up from 20 to 80.

 

Note that most effect types (intensity, twinkle, shimmer) have maximum possible values of 100, so for those effect types this means the same thing as "any intensity will be increased by 20".  However, the DMX intensity effect type has a maximum value of 255, not 100, so for it, increasing with a percent of 20 means increasing by a value of 51 (i.e. 20% of 255).

 

If the increase pushes any intensity above the effect type's maximum possible value, it will be set to that maximum.  For example, using a percent of 20, a fade up from 50 to 90 will be changed to a fade up from 70 to 100.

 

Reduce

 

The Reduce operation decreases all intensities in the selected area by the specified percent of the effect type's maximum value.  For example, using a percent of 20, a fade up from 50 to 60 will be changed to a fade up from 30 to 40.

 

Note that most effect types (intensity, twinkle, shimmer) have maximum possible values of 100, so for those effect types this means the same thing as "any intensity will be reduced by 20".  However, the DMX intensity effect type has a maximum value of 255, not 100, so for it, decreasing with a percent of 20 means decreasing by a value of 51 (i.e. 20% of 255).

 

If the decrease pushes any intensity below zero, it will be set to zero.  For example, using a percent of 20, a fade up from 10 to 90 will be changed to a fade up from 0 to 70.

 

Scale

 

The Scale operation scales all intensities in the selected area by the specified percentage.  For example, a percent of 200 means doubling; a fade up from 30 to 40 will become a fade up from 60 to 80.  A percent of 50 means halving; a fade up from 30 to 40 will become a fade up from 15 to 20.

 

If the scaling pushes any intensity above the effect type's maximum possible value, it will be set to that maximum.  For example, using a percent of 200, a fade up from 30 to 80 will become a fade up from 60 to 100.

 

Channel Types

 

The Channel Types section has four different checkboxes: Non-RGB, RGB Red, RGB Green, and RGB Blue.  Which ones are selected determines which channels the Change Intensities tool will apply to.  For example, if you check Non-RGB and RGB Red, but have RGB Green and RGB Blue unchecked, then the tool will apply to any red channels found in RGB channels, and also to any channels that are found outside of RGB channels, but it will not apply to any green or blue channels found in RGB channels.

 

Channels that are found as macro channels of Cosmic Color Devices will always be skipped.

 

Note that a channel can appear multiple times in a sequence, or even multiple times in a track, and it is entirely possible that one of its appearances is (for example) as a green channel of an RGB channel, while another appearance of the same channel is outside of any RGB channel.  The Change Intensities tool is not particularly smart about this sort of thing: When deciding whether or not the tool should apply to a channel, each individual appearance of the channel in the sequence is considered independently of any other appearances it may make.

 

Apply

 

The Apply button applies the Change Intensity tool to the currently selected area, using the various options set in the Detailed dialog.  The dialog will remain open, so you can use it several times in a row with different option settings and/or on different selected areas.  To close the dialog, click the Windows close "X" button in its upper right corner.

 

Quick

 

The Quick menu item on the Change Intensities submenu will be greyed out until you first use the Change Intensities tool (the first time you use the tool, it must be done through the Detailed dialog).  After that, it will instead show the options that you most recently used for Change Intensities.  For example, if your last use of Change Intensities was to apply a floor of 37% to red and green channels, the Quick menu item will display as "Floor 37% on red, green", and clicking on it will apply a floor of 37% to red and green channels in the selected area.

 

Recent

 

The Recent menu item on the Change Intensities submenu is similar to the Quick menu item, except instead of one single item, it is actually a submenu of the up-to-ten most recent uses of the Change Intensities tool.
