Understanding QLab Fade Cue: A Comprehensive Guide

QLab is a powerful audio and video playback software that offers a range of features for creating professional-level productions. One of its most useful tools is the Video Fade Cue, which allows you to adjust the transparency of your videos, enabling fade-in, fade-out, and cross-fade effects on movies and still images.

Final Visibility: Opacity Control

The final visibility specifies the opacity of the target video when the Video Fade Cue ends. This setting allows you to control the level of transparency at which the video will be displayed once the fade is complete. Additionally, relative fades can be applied to Group Cues to adjust the opacity of all videos within the group.

Relative Fades: Adjusting Opacity

A relative fade adjusts the opacity up or down relative to the current opacity, whatever it may be. For instance, if one Video Fade Cue is performing an absolute fade on a video and another Video Fade Cue begins another absolute fade on the same video, the second Video Fade Cue takes over as owner of the video.

Absolute Fades: Specifying Opacity Levels

An absolute fade adjusts the opacity to a specific level. When an absolute fade begins, the current absolute opacity of the video is checked, and the Video Fade Cue computes a fade adjustment from that initial opacity to the specified final opacity. These types have the following characteristics:

* Adjusts the opacity to a specific level.

* Allows you to specify the target cue will be told to stop when the fade is complete.

Setting Duration: Triggering Crossfade

You can set the length of a Video Fade Cue using the duration parameter. When you're ready, trigger the 'Crossfade to park' cue to start the crossfade process.

Creating a Group Cue for Crossfading

To create a group cue for crossfading, follow these steps:

* Place the 'Park' cue and both Fade cues within the Group cue.

* Set the mode of the Group cue to 'Start all children simultaneously.'

* Create a Group cue and name it 'Crossfade to park.'

* Select the 'Park' cue and bring its master level to -inf.

* In the Levels tab of the inspector, click once on the master level text field to turn it yellow. Set the duration of this Fade cue to 10 seconds.

Creating Relative Fades for Crossfading

To create relative fades for crossfading, follow these steps:

* Create a Fade cue that targets 'Park' and sets its level to -inf, with the Stop target when done box checked.

* Set the levels of that cue to suit your taste and needs.

Conclusion: Mastering QLab Fade Cue for Crossfades

In conclusion, mastering the QLab fade cue is essential for creating professional-level productions. By understanding how to use relative and absolute fades, you can create seamless crossfade effects between videos, audio cues, and scenes. With practice and patience, you'll be able to craft stunning multimedia presentations that captivate your audience.
