I have just confirmed that the corner-pinning and flipping in Stage Setup does transfer to Blackmagic Output, you just need to enable Blackmagic output for the Display itself instead of for the Stage, then do the flipping and corner-pinning on the Display, not the Stage.

1. convert from a port on your mac to the connection on the beamer?

2. Extend the signal from your mac to the beamer?

3. Possibly decode a signal from an extension system to the beamer?

The issue you report (unavailble resolutions) sounds like part of your chain is not able to handle the bandwidth you are transmitting over a the cable/convertor setup you are using. Can you test the directly plugged in port and cable/convertor chain piece by piece with different convertors and cabling (the ones you know work)?

If there are any features on your projection surface - door edges, holes, ridges etc it can be useful to mark them on the line up pattern too, as long as you measure them exactly and put them in the right place on the line up - it can make your line up faster and more accurate as you can quickly put the corners in the right place and drag the features to match.

Having perfect squares in your test pattern is very useful, you can measure projected squares with a tape measure and see if they are actually square.

It would be nice to have an option in the Stage Setup to deactivate an output (e.g. Display Setting = NONE). Further it would be nice, that Isadora recognizes, which parts of a stage are deactivated and does not calculate these outputs to save resources.

Background:

We had a theatre production with 6 beamers and a Control Monitor running on a Windows 10 computer. 4 beamers were connected to a videowall processor, which were recognized as tow wide screen monitors by Windows, so we had in total 5 monitors showed in Windows.

Once during a rehearsal, we had an electrical damage on the computer and we had to replace it a week before starting the show and during a period, where it was really hard to get computer hardware. We were not able to find a computer with a graphics card, which can output to 5 monitors on a single graphics card (since Isadora only support that), the maximum was always 4. We tried a long time to find a way to work with only 4 monitors but we were not able.

So we decided to use a Laptop for one beamer and connect the remaining beamers to the computer and just let run Laptop and Computer the same Isadora show file except for a different configuration in Stage Setup. As fare as I know, there is no possibility to deactivate an output. So we had to remove all projector actors for the one beamer on the computer show file and we had remove all projector actors for all other beamers on the laptop show file, which also took a lot of time because of 80 complex scenes.

I think that such a deactivate output feature a situation, where each minute counts, would be really useful since one can just take some laptops, copy the show file, connect the beamer to it, deactivate every output, which is not connected and let the show run.

Thank you very much

I'm still having trouble getting the mouse wheel to control the zoom. It doesn't seem to deal well with feedback loops. I want to get a value, add the scroll wheel delta, and put it back in that value. But even watching for triggers, I haven't gotten it to work cleanly. Seems to add the number a bunch of times in a loop.

For now, I'll just use right-mouse-down with vertical position for the zoom.

So I have left-mouse-down to drag the box around the screen and right-mouse-down to change the zoom. It's working well enough, but it seems kinda hard to get the mouse wheel controls to do what I'm looking for.

thanks, that will be a useful workaround. Very helpful.

But I would still be curious to know if any Catalina users are able to use the QC KeyEventEmulator...

@woland yes! thanks, it's pretty much the same idea of using a TripleHead right? I'll try this

 Yes, sort of. Making it one big video really helps things stay in synch. You may run into issues if your aspect ratios differ though. This method is also excellent when you're trying to edge-blend content across multiple projectors.

I'm pretty much convinced the main problem I'm seeing (Prores files not playing back so reliably; see above) has nothing to do with the Ultrastudio output, given that GLSL shaders play back near-flawlessly.

You may want to look at @mark 's video tutorials for Value Scaling

Part 2

I know this means going back to CPU actors but the fluidity of the video card/box is much better than a graphics card.

Thanks
