      Hello,

      Looking for a way to fade between scenes on a custom curve. Would like the option to do s-curves, equal power, etc. I don't see any options for this in 2.2.2\. Thoughts?
      Thanks!

        @AlexWilliams,

        We don't have that yet. You'll have to submit this as a feature request.

          If you create the curve and attach it to the scene intensity you should get the desired effect.

            @Mark; thanks, will do. Would be a great finesse point to have. Where can I submit that?

            @Fred: sorry you mean put the fade to 0, then fade in using and envelope generator attached to a curvature actor? That would work if there's a dip to black, right? It wouldn't work in a scene crossfade situation, right? Unless I'm misunderstanding...

              Instead of the fade or jump use activate scene amount from a master scene. You can then use an envelope generator and the curvature actor to create the curve you want (in data) and attach that to the intensity of another scene. Here is a crude example, you will need to play with the curvature to get the kind of fade you want, of course you can connect a different curvature to each scene (and even different ones for fade in and fade out if you want). 078e55-scene-fade-with-curve.izz

                is there any way to manually control the fade via midi/other controller? for use with live music production. Having a pre-determined fade duration is limiting my control and leading to clunky and clumsy transitions between tracks.

                  have a basic functional solution here. the only problem is that i have to leave a blackout between the scene I'm mixing from the one I'm going into. I have to manually fire a jump actor when i'm happy the previous track is finished, with an enter scene trigger in the blackout which takes me straight into the target scene however i get a brief flash of darkness while the blackout trigger runs. it's not the end of the world but it would be nice to have continuity. for some reason without the blackout scene as a buffer it loads the scene i want but nothing within it is active or can be activated. Any suggestions. 078628-screen-shot-2016-04-22-at-12.07.34.png

                    How about a 'null' scene that just has an enter scene triggering a jump to next scene so you fully transition into black for 'N' milliseconds and then into the next new scene?

                      @skulpture; I'm trying to not have to go to black. for a continuous set the blackout creates a punctuation I don't want, but for some reason with the fader set up I have once I leave the scene I'm coming from the scene I'm going into stops.

                        @DIarmuiD - do you need to use scenes? or can your project be built in one scene, using envelopes to fade between projectors. i only use scenes when i know i can interrupt the flow. i've never found transitions between scenes to be as smooth as transitions within a scene.

                          Had considered this. 2 problems i encountered (1)  processing power. too many videos running slowing down my machine significantly. within each scene  I have at least 2-3 videos each with at least 2-3 effects and using midi to control parameters (2)  using a midi controller with limited controls and notes.

                            (1) If videos aren't playing when they aren't being used, then they're not using any processor. (i often use an envelope to fade out a vid, then send a value of zero to the Movie Player speed input, triggered by the end of the Envelope Generator)
                            (2) Are videos being played sequentially? you can use a Counter actor to increase movie numbers within the same Movie Player, or a Counter and a Selector to route the MIDI controls to different players in sequence.

                              Thanks a million, i am jumping between videos so there is no set sequence within each sub set, but the counter selector combo may prove to be a solution. will see if i can make this work. Thanks again.

                                    Here's another solution to try. @bonemap was saying that the GLSL Shaders crashed Isadora on their computer, but you can always pause the engine (Shift+Cmd+P) then go into that Scene and replace those with something else. 

                                    This works on the same principle as @Dusx 's "SYSt3m", putting complex programming inside Macros, all controlled via the same Scene, because any User Actor/Macros that are inactive, (via use of the User Actor On/Off), won't leech any processing power. I ran with this idea and suggested putting entire Isadora Scenes inside of Macros. I'll be refining this and making it into its own forum post at some point in the near future.

                                    Multiple Macro Scenes 1.2.zip

                                           Thanks for the offer, but I have some specific ideas on how to improve the modularity and flexibility of the system using new features within Isadora. 
                                          Also, specific integrations with custom plugins, that I am far from ready to release ;)

                                          As I learn, I will post and share. I'm sure a couple tutorials will come.

                                            Wondering if anyone knows what the default fade actually is in 2.5.2 - it seems like a linear fade, is that the case? Perhaps an obvious question, but curious as to what it was programmed as.
