offset in crossfade ?

Hi,

I'm sound and light technician in an amateur theatre company and we are using only static lights/dimmers, no moving things.
Until now we have been using Sunlite 2004 for our performances, but as Sunlite 2004 only runs on WinXP and 32bit machines, we are thinking about finally switching to something else ... in comes QLC+ on a Linux Mint PC with an Enttec openDMX box !

BUT ...

When creating chasers with all our scenes, for "nexting" through during a performance we program in the crossfades between the scenes.
In Sunlite we can set an offset, to a fade-out or to a fade-in ... which is very usefull (for example we want a slow fade-out of a scene, and when almost completely faded out, we want the next scene to fade in ... easily done by offsetting the Fade-in of the next scene by a few seconds ... very handy and very frequently used ...

How is this done in QLC+ ?
I don't see any possibility to put in "offsets" in the fade parametres ...
Am I missing something, or is there some work-around for this ?

Please help me out on this ...

Greetings

Not sure about you question, but each scene can have a fade in/fade out time, thus "nexting" through a chaser inside a cue will fade ...
See attached sample ... fades two RGB between red and blue and vice versa

So....what´s wrong with my sample ? Doesn´t it work like you expected ?

Try using a 'dummy' scene (generic : not used in 'real' life)
ie : scn 1, dummy scn, scn 2
the dummy will have a hold time equal to your offset.
so scn 1 starts fade out, dummy holds, then scn 2 fades in.

I do a little bit of amateur theatre work and sometimes find I need to put in some extra scenes just to get the effect I want.

In this case, if you added a copy of the original scene and then adjusted it to the dimmed levels at which you wanted the next scene to start fading in, then you could achieve your offset. It is a bit fiddlier but probably gives you a bit more control over the whole look.

See attached workspace with an example. I have created two cue lists to show the difference. You might need to adjust the fade times to suit the effect you are looking for.

Cheers

I did some experimenting with a blackout scene used as an offset. It seems to work quite well but the scenes I used were pretty simple. Not sure what will happen with more complex ones.

In terms of work flow it probably is a bit quicker as you can just keep adding the same offset scene to the chaser and then give it a different fade in time.

I have added it to the virtual console for you to experiment.
