The decibel domain uses a logarithmic scale. The slider domain emulates the design of physical sound consoles, maximizing the useful range of audible levels and making a straight fade sound as smooth and natural as possible.
This drop-down is only relevant to the Audio Levels tab. The Audio Domain drop-down menu lets you choose the scale that QLab uses to fade audio levels. This option provides a straight, linear fade curve.
This allows you to use a mathematically precise parametric fade shape. If you choose this option, a text field labeled Intensity appears below the drop-down menu. To start over entirely, click Reset to Default Shape in the bottom left corner of the tab. To delete a control point, click on it to select it and press the delete key on your keyboard. This option allows you to click anywhere along the fade curve and a create control points, which can b dragged to change the shape of the curve. QLab’s default curve shape follows an “ease-in, ease-out” envelope designed to sound natural with audio levels and look smooth with video geometry. There are four options for Fade curve shapes. The curve shape that appears by default is set according to the Fade cue’s template, but you can choose another fade shape from the drop-down menu in the top left corner of the tab. The curve on the left is for levels which are increasing, and the curve on the right is for levels which are decreasing. The fade curve, drawn in yellow on the right side of the tab, determines the rate of change of the parameters being faded. The Basics and Triggers tabs are the same for all cue types, and you can learn more about them from the page on the Inspector in the General section of this documentation. When a Fade cue which targets a Video, Camera, or Text cue is selected, seven tabs appear in the Inspector:
#QLAB SOUND CUE HOW TO#
To learn how to set a target for a Fade cue, please refer to the section on targeting other cues in the Getting Started section of this documentation. The word “fade” can often be taken to mean one thing or another, but in QLab “fade” simply means “change a value over time.”įade cues require a target and a duration, and must adjust at least one level or parameter. Fade cues can also target Audio cues and Mic cues when a Fade cue is selected, the inspector will only show the tabs relevant to the type of cue that the Fade cue is targeting. A Fade cue can be used to adjust the opacity, translation, scale, rotation, video effect parameters, volume levels, and audio effect parameters of a targeted Video, Camera, or Text cue.
