Here are a couple of example patches I made in the past covering this topic. They're probably similar to what @bonemap already posted, but maybe they'll be helpful too.

@ericksommet

It's not exactly what you're asking for, but here's some resources that might help you learn more about this concept in Isadora:

Example file I created that covers the basics of motion-tracking: https://troikatronix.com/add-ons/tutorial-basic-motion-tracking/

In-depth live-stream Guru Session by Mark Coniglio, the creator of Isadora, focused entirely on motion tracking with the Eyes++ actor: https://www.youtube.com/watch?v=RKSwV4vjq7o

Example project file I made for someone on the forum that used motion tracking to trigger things: https://community.troikatronix.com/topic/6213/dining-experience-using-isadora-advice-please/6?_=1711366182217

Will do!

@woland

Thank you so much for this detailed answer to my questions!!!

This is very helpful!

Hi!

My Audio card is Realtek(R) Audio.

Thanks for your help!

@nitnatnoe

I recommand the NDI way with a good gygabite (minimum) ethernet link and a properly configured network.

The HDMI way its also CPU hungry, you are limited with the distance between machines, you must buy a card and the settings are not so trivials.

With a proper network, you can also send other informations from TD to Izzy and vice versa.

There's also a written tutorial here: https://support.troikatronix.com/support/solutions/articles/13000046020-how-to-run-multiple-scenes-simultaneously-using-the-activate-scene-actor

@dillthekraut lots of places have fibre, especially for very long runs. Reels of rugged cat7 are multi use so they are pretty popular. This is especially true when you only need a single converter when the projector has built in hdbaseT

Should we be concerned that you are needing motivation? 

Nah, I just ran across this while looking for something else and found this (though I appreciate the concern). Past me didn't have easy access to a printer but present me does. I like to keep little mementos around my desk that make me happy and I thought this would be a nice addition. <3

Best wishes,

Oh whoops I put a screenshot from Isadora 2 from an old post because it looks really similar to what I was actually trying to show which is this:

I edited my post above to remove the incorrect information.

It can be done in a myriad of ways, using multiple hardware and software combinations. Neither will be easy or hard. It all depends on skill and - in the end - time and money. 

@jfg, @bonemap @CitizenJoeGreat,
Thanks that worked:) really nice!

The times are delayed so all three videos stop at the same time and fade to black. Is that possible?

Triggering Things in a Sequence in the Same Scene

Enter Scene Trigger actor > Timed Trigger Actor > Sequential Trigger actorAlternatively: Enter Scene Trigger actor > Timer actor > Comparator actors looking for each time when there's supposed to be a trigger.Set the 'mode' of the Comparators to greater than or equal to ("ge")Initialize the first value input of each Comparator at '0'.Connect the output of the Timer actor to the first value input on each Comparator actor.Note that the Timer actor outputs milliseconds, so if you want a trigger at 3 seconds, put "3000" into the second value input of the Comparator actorFade in and fade out within the same Scene can be handled by Envelope Generator actors hooked up to either a Video Fader actor, a Video Mixer actor, or the 'intensity' input of a Projector actor.

Triggering Things Across Multiple Scenes/With Scene Transitions

Enter Scene Trigger actor > Trigger Delay actor > Jump actor if you want a scene to automatically jump to the next oneFade in and out while transitioning between Scenes can be handled by the Jump or Jump++ actors' fade inputs.Fade in and out of background Scenes can be handled by the Activate Scene Amount actor in combination with Envelope Generator actors.

@woland Thanks L much appreciated!

Best wishes,

@woland

Brilliant.  Thank you!

@mark_m said:

but how do you do this?

 ! Quick Answer: Use the Background Color actor to create a 'canvas' that will fit all your stages in one.

Here is an example file create in Isadora 3.2.6

It requires for 1920 by 1080 video files as sources. (you can swap in any 4 sources of the same size).

NOTE: I use a Shapes actor to generate some 'sprite' and animation in this example, but if you wanted to animate an Image or Video (picture player or movie player) across the large canvas, I would replace the MultiMix (and shapes) with the Player (movie or picture) and another Matte++, again with 'scale FG' set to off. In that state it works amazingly as a compositor/animator of 'sprites'.

@nic

Any thing will work actor wise, you don't need to use an absolute value actor, the import thing is that the loop doesn't get fed back into the system from one point

encoded H.264

 Playback will be smoother with a non H.264 encoding. (this encoding requires more than a single frame be loaded for each frame show.. so loops are problem-matic and reverse playback is terrible). If you create HAP files (or prores) each frame can be shown when only the data for that frame is loaded. You can find hints about the quality/usage of your video media in the media panel when you rollover/hover over an imported file.
