The Precision option lets you decide whether the parameter will accept Floating Point or Integer values.
The Default value text field lets you enter the initial value of the parameter when the plug-in is first applied.
The Minimum value and Maximum value text fields let you set the range of the slider control.
The Increment text field contains the value that the parameter will be changed by when the arrows, rather than the slider's knob, are used to increment or decrement the parameter value. Please note that the increment value is only a suggestion to the host. Depending on the current UI configuration, the host may decide to use a different slider increment than the one you supply.
The Absolute minimum value and Absolute maximum value options let you decide whether the user is allowed to specify a value for the parameter that is below or above, respectively, the limits set for the slider. The ability to over- or under-shoot the parameter value is currently supported only in Motion.
Contrary to Motion, Final Cut Pro and Final Cut Express only allow users to enter values between the Minimum and Maximum values allowed by the slider. To overcome this limitation when creating sliders in those hosts, FxFactory will use the Absolute minimum and Absolute maximum values as the slider range.
The Scale value when previewing at reduced resolution option lets you control whether the value of this parameter will be scaled down when the user is previewing the effect at lower resolutions (e.g. half-resolution). The parameter value is scaled by the same factor being used for previewing the effect (i.e if the user is previewing at half-resolution, the value will be divided by 2). This option allows an effect to always appear consistent even when the preview resolution is different than the resolution used for rendering. This option should be on for all parameters that express a geometric property such as distance, radius, height or width.
