Collections with the same scene in a cue list...
Posted: Fri Nov 27, 2015 2:20 pm
Hi,
I am using QLC+ 4.10.1 on a raspberry pi 2. I have noticed this issue on my standard linux (64bit lxde) machine too so it's not related just to the pi.
I use QLC+ in a pretty traditional theatre way, using scenes to define my basic "states" and then a chaser to make my cue-list which I step through during the show.
I discovered that I can use collections in order to layer multiple scenes together. This seems to me to be a very powerful feature for theatre. For example I plotted all the scenes for an entire show with the director about a week ago. We then managed to get hold of some RGB LED bars which we are using as footlights to enhance certain scenes. In order to make things easy for me, I made a few scenes just for the footlights, like "footlights blue", "footlights orange", "footlights white", etc.. Then, for those scenes where I wanted to add the footlights, I made a collection which comprises of my original scene plus the footlights scene. So for example I now have a collection called "inside aeroplane + blue footlights". This meant I didn't have to go through and edit multiple scenes. It also meant if I wanted to adjust the level/colour of the footlights, I could do it in one place, rather than having to edit loads of different scenes.
All good so far. The problem happens once I am running through these scenes and collections in a cue list.
So I have:
Scene A: inside aeroplane
Scene B: footlights blue
Collection C: A + B
In my cue list I have:
Cue 1: Fade in A 2sec, infinite hold, Snap out
Cue 2: Snap in C, infinite hold, Fade out 2sec
I would expect that the transition from 1 to 2 would be seamless (as C contains A), with the exception that the footlights would now be on. However, I experience a small "glitch" where scene A stops and then starts again with the result that all the lights flicker off and on again. It must be only a few milliseconds but enough to be noticeable.
This is only a very simple example. I have a few other collections which contain 3 or 4 scenes where the same thing happens. It's really handy to use collections for this kind of thing. Maybe I'm expecting too much, or not understanding some basic principle?
Anyway, thanks for listening.
John.
