![]() ![]() 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: 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. Since relative fades are additive, and the Audio cues are now playing at -10, you’ll end up with very very loud sounds.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. Do be very careful not to accidentally run that Fade cue twice while the Audio cues are playing.Now, when that Fade cue is triggered, the Audio cues within the Group will have 49 dB added to their level, bringing them to -10 as planned.Create a Fade cue targeting the Group cue, and in the Levels tab of the inspector, set the master level of the Fade cue to +49.By default this is -60 so if that has not been changed, set your Audio cues to -59. Once all the Audio cues sound good, bring each of their master levels to 1 db louder than the minimum volume level established in Audio settings.If -10 is too loud or too soft, use the individual cue output levels for each Audio cue to get the right loudness.For now, let’s agree on -10 for that level. Set the levels of all the Audio cues in that Group such that their master levels are the same. ![]() Create several Audio cues and place them within a Group cue to your taste.What to do? The trick lies in starting your cues just slightly louder than -INF. This is a problem when your goal is to fade in several sound cues from -INF to some audible level, because -INF plus any amount is still -INF. Because the starting state of each child cue may be different, Fades which target Groups can only be relative fades. When a Fade cue targets a Group cue, QLab attempts to apply the result of that fade to all the child cues within the Group. ![]()
