@woland Amazing resource! Thanks SO much...  - John

I don't suppose you know of a way to package that up as a skeleton output that the decoder would recognise?

Unfortunately, it is not currently possible to programmatically create data with the special type "skeleton".

@dbini Thanks!

@dusx Thanks. Given this, as most of my calculators are used in momentary situations (button press, dial turn) I think that Javascript makes more sense. It greatly simplifies my patching. If I run into a situation where they are updating as a stream, I'll try to use calculators. 

I appreciate your input. 

Best, J

projected stages keystoning

It's also worth noting that you can also make a background Scene where you send all your video and then route it to the right Projector actor. Using this global projection mapping method, you only ever need to have one Projector (in the entire file) per Stage if your keystoning/mapping is the same for every Scene. It has the added benefit that if you ever have the need for different keystoning for the same Stage within the same file in different Scenes, you can use this same method, but use the actor chain Enter Scene Trigger > Trigger Value (2) > Broadcaster in the Scene that needs the "specialty" mapping/keystoning to affect a Router actor in the background mapping Scene to change the video's route so that instead of going to the "normal" mapped Projector actor (1 on the Router actor) the video goes to the "specialty" mapped Projector actor (2 on the Router actor), then have another Enter Scene Trigger > Trigger Value (1) > Broadcaster in the next Scene to switch the Router back.

Wow that is such a detailed a very complete answer / explanation !

There are almost always multiple ways to accomplish the same task in Isadora, so I like to give examples of different methods because some may be more or less well-suited for a particular use case. :)

PANASONIC GH4 DSLR > ELGATO HD60 S > ISADORA. Has anybody been able to make this setup work using the GH4 for live capture, as my laptop will not recognize the the Elgato device? Elgato does not show up in Quicktime or any of the Elgato softwares. Any guidance and advice would be much appreciated. I'm using Izzy 3.2.6 in a Macbook Pro, 8 GHz Quad-Core Intel Core i7, Ventura 13.2.1.

I also looked at @dusx's multi toggler which uses javascript, but it does not seem like a fit for this problem.

 Just to provide a link to my Toggle User Actor, since it may be helpful to others that come across this thread: TROIKATRONIX : ISADORA - DX – JS – Multi Toggle

@woland I agree with you, but in this case As a challange to myself I wanted to try to replicate the treatement and have the occasion to think mathematically. I'll try.

@gapworks

I allready suspected, you would go there. But I wonder what you actually need to change here? The resolution and aspect is defined by the systems OS display settings. The only thing you might have to change in the stage setup settings, might be the selection of the right display. As far as I know, there is no other possibility beside GUI and mouse. But in general, if you allways use the same physical output, you most times don't need to change this manualy. The resolution here, will be changed automaticaly, matching the resolution set in the systems OS display settings.

If the aspect doesn't change, Isadora will then allways scale to the full physical output. No need for other changes.

But things get complicated, if content and output aspect doesn't match.

See this not to old thread about it.

It shows the same issue, from the other End.

@Woland made a nice patch, which shows  how scaling in isadora works and which options you have.

@dillthekraut Thank a lot ! That would have been what I would have done (more or less) but I was in a production so I didn't have time and resources to test it in that way. I'll definitely look into it and report it here as soon as I can. Interesting case 

@bonemap you can use any video editor. If you have the multi channel audio you can use shutter encoder to add it to or replace the audio on an existing movie (must be exactly the same length). If you need to do it for an avi virtual dub will do it.  You will generally need to start with a 6 channel wav file for 5.1. 

You are right the multichannel audio capabilities on the movie player are lacking. You can play multi channel audio fine though and although you cannot route on the fly you can change the channel order in your audio setup on your computer. Alternatively most modern sound cards will let you do routing and some like RME will let you control the routing with osc or midi. 

If you need to route multi channel audio inside and SDI signal it’s pretty common to use an SDI audio embedder. This lets you combine the outputs from an audio mixer with the output of a video system and have control over line delays and channel order. 

@jtsteph

I'm very interested to know what this looks like in practice.

Also, I realized that this User Actor that I originally got from @mark and then modified might be useful for similar use cases as well (though probably not for your exact use case).

I also hope I'll be able to find the time to finish the file soon...

@Bonami I just finished the file in my After Hours Isadora Lab. Here's the file: redundancy-heartbeat-switch-2024-02-29-3.2.6.izz

The file and the link to a recording of me building this addition to the file will be posted in the Isadora channel of the Office Hours Discord soon.

This updated file includes an example Content Scene:

One of the things this Scene does is explain how to keep your Scene List in Synch across the two files (it's the section at the top right labeled "#Keeping the Active Scene in Synch Across Two Files").

Here's the guts of the Macro from "Method 1 - Next/Prev Scene" (I'd recommend the second method instead though):

Here's the guts of the Macro from "Method 2 -  Scene Synch" (I'd recommend using this method):

It's possible I made a logic mistake somewhere, as I haven't tested extensively with two computers, but feel free to let me know if you encounter problems and I'd be happy to fix the file.

Best wishes,

Woland

@woland

They just confirmed to me that they were using the preview.
Already solved !!
Thank you Lucas for everything, as always (you were right)

other (negative) consequences

 The Ungrouped layer method allows you to 'interlace' image layers during scene transitions. This can create some very interesting effects, since Projector layer settings are used.
However, this method is not default since by default it mixes scenes in an additive manner, where the newer Grouped by Scene option flattens each scene individually and mixes them with a more 'cinematic' crossfade not possible with the Ungrouped option.

@fred and @DusX 

Thanks for the heads up. I did get the integrated GPU working alongside the dedicated GPU just as a test. Next step will be to get all four projectors hooked up and build some test cues to see what happens...

I also want to check the Star-Tech extender to see if it works as an option... 

@jandraka

thank u so much for this hint. now it works like charm.  just in time! Although i had to redo the whole patch.  

@riodio You also normally have to use Z translate to move the object backwards, so its comes into view. I normally start at -50

@dbini 

Oh! You are absolutely right...I don't know why I didn't see it.
I'm going to explore it and maybe come back with new questions. Thank you very much for opening my eyes!
Best,
Maxi
