You start the track and the fade cue plays at the same time. You can use the auto continue function to trigger the fade at the same time as your other sound cue.
Return typeĬreate a parameterized circuit and assign the parameters in-place. You make a fade cue, set the level then another cue to fade it back up again. ValueError – If parameters is a list/array and the length mismatches the number of freeĪ copy of the circuit with bound parameters, if inplace is False, otherwise None. Buy a discounted Paperback of QLab 4 online. If True the circuit instance itself is modified.ĬircuitError – If parameters is a dict and contains parameters not present in the Booktopia has QLab 4, Projects in Video, Audio, and Lighting Control by Jeromy Hopgood. Inplace ( bool) – If False, a copy of the circuit with the bound parameters is returned. Parameters ( Union ], Sequence ] ]) – Either a dictionary or iterable specifying the new parameter values. The values can be assigned to the current circuit object or to a copy of it. If parameters is passed as a list or array, the elements are assigned to theĬurrent parameters in the order of parameters which is sortedĪlphabetically (while respecting the ordering in ParameterVector objects). The values of the dictionary can either be numeric values If parameters is passed as a dictionary, the keys must be Parameter
Basically this involves 3 cues all set to auto-continue you play video 2 0 opacity, you fade video 1 down and fade video 2 up. assign_parameters ( parameters, inplace = False ) ¶Īssign parameters to new parameters or values. Folks often get confused doing fade-ins in QLab since you have to start the video first, at an opacity of zero and then apply an animation cue to it that brings the opacity up.
