Higher-resolution video output will tighten things up. Each pixel is very multiplied by the nature of projection, so squeezing more into the same space by using higher resolution images/projectors will make things much cleaner looking.
But if you really need to soften the edge inside Isadora you can create a mask using Izzy map with a white video feed, sent to a virtual stage that you then grab and apply as an alpha channel to your actual output. In this way you can apply a blur to the black and white image before using it as the alpha mask.. this will give you soft edges.

@dbini

Ah yes, I see, I use Get Stage Image, and the the Calc Brightness. Great, thanks! it seems to work. 

@citizenjoe aye thanks. For some reason i couldn't find that. Much appreciate

@flobandy

Hi, can you tell us what computer operating system you are using?

@fubbi Thanks, I'll check it out, though the activate scene actor is not the issue. 

In the meanwhile I figured it out. The fade between doesn't work, but a ramp generator changing the intensity of the projector with the mode set to 'transparent' does fade in the video as wanted. Going out of the scene and back to the 'background loop' does work using the standard scene transition fades.

Finally figured out a workable solution. Here it is if anyone else is interested in creating this particular functionality:

A few months ago @mark showed me something similar that he does with the Pulse Generator actor feeding a Float Counter or Counter actor to get smooth values going up or down. Super clever!

@dusx

Yes! Thank you.

@fred

thanks Fred, i will investigate....

How to call an Applescript file inside the patch?

 you can also use Osculator ( 22€) to run an apple Script. In Isadora send an OSC message (e.g. with a waveform actor) to Osculator 

and set in Osculator the received message to start the Apple Script:

I sent you a DM.

For instance, can an envelope generator actually impact a control panel slider beyond "showing value of linked property."

 @dimitrisC I took the above to mean "do something beyond updating the Control Panel visually". Indeed you can do many things to update the Control Panel visually, but nothing you do in that respect will push values from the Control into other actors.

@woland merci

@dusx

Naturally while trying to make you a cleaner patch I found my error. Must have thrown a black background into a video mixer somewhere in my efforts to make the assets transparent — which only showed up once I had ungrouped layers, thereby masking everything. Ungrouping works(!) ... which is what you all said in the first place. 

As always, thanks for being willing to check my work.

I just remembered Mark also did a Guru Session that covers background Scenes: https://www.youtube.com/watch?v=rq8ZhvK6vSM

@jeisenman

You could use Isadora:

With a USB-DMX device or ArtNet device (tutorial) to interface with a commercial or homemade DMX-controlled projector dowser.You could use the TCP/IP actors, User Actors (Sanyo, Christie), or the Send PJLink actor to control a built-in shutter if your projector has one and accepts PJLink commands (some also have Artnet-controlled shutters).You could modify a CD tray to make an improvised dowser and control it with an Arduino using the Arduino Firmata plugin (discussion).

Best wishes,

Hi,

Sorry for not replying, I just found out that watching my own posts was not activated by default in the forum, so I completely missed the last replies...

Thanks for the ideas, I'll investigate further next time I need to receive Art-Net in Isadora.

Oh that is too bad. But many thanks for the explanation!

@woland

thanks buddy, i thought someone might like to tinker with it. interesting to note that user actors created with the beta are not accessible to the public release.

Thank you very much ! :)

Let me know if there's anything else I can do to help or if the file isn't clear enough.

sorry for the looooong title

Don't be, it was an absurd and amusing issue to solve. I typed my reply and then spent about two minutes trying to figure out where the "Submit" button was before I realized that I'd have to edit the title of the topic before I could respond. 😆
