Crazy, right? I think I'm most confused by seeing it work on other machines. Maybe a driver update would help?

Thanks Mark!

Best, Matt

Whoa golly what a snipe hunt am I on in this theatre.

I upgraded the MacPro to Isadora pre-release 1.3.1f06.

• In doing this I'm able to force preview to the CI projector at resolutions less than or equal to 1024 x 768 (Mark, when I made the force preview window larger I was only getting a black stage).
• Using the Image to Video and connecting to a Projector actor, I see a black stage both in forced preview, and displaying only to the stage.
• There's no difference in performance with or without remote access.
• The long and the short of it is that on the Mac Pro in the theatre, quartz does not behave in 1.3.1f06

I did some additional tests on my computer at home and like you I'm not having any issues rendering to an external monitor. For my home test I'm running OS X 10.8.4, and Isadora 1.3.1f06 to match the set-up of the theatre. Huh.

Mark - when I get to the theatre tomorrow I'll try a force preview at a stage resolution of 1920 x 1200 and report back on the results. In programming the show I have been using remote access over a wired network to screen share with the Mac Pro. Is there any chance this is causing a problem?

Tomorrow I'll try both:

Force Preview at 1920 x 1200

No Remote access

Thanks again for the extra help on this gentlemen!

Best,

Matt

I can try it on an external screen tomorrow though but technically it should be no different should it?

My initial tests on Mac OS 10.6.8 worked as expected -- no crashes or problems with a 1920x1080 external monitor. I'll try with 10.7 later, but won't be able to try with 10.8 immediately because I'm away from home for the next three weeks and won't have access to my Mac Pro. But the laptop isn't a totally fair test, because things can be a bit different when you have a discrete GPU card as you have in the Mac Pro.

Matt, can you set your force stage preview size (in the Stage tab of the Preferences) to 1920x1200 and see if this stops the patch from working? (If the QC patch were for some reason to exceed the maximum texture size because of the output resolution, this could cause a problem.)

Also, ensure that the 'stage' input on the QC actor is set to the actual stage you will use when you're showing it on the Barco.

Maybe Graham will find a problem if he tries it. Graham?

You two are phenomenal.

Alright, included here are the quartz composition and an Isadora patch with two scenes:

CI projector - the patch using the CI projector

Video Projector - the patch using a video projector

As a note, on my end both work in Forced Stage Preview, but only the video projector scene works when outputting to an actual projector. I've tried this at resolutions of everything between 800 x 600 to 1920 x 1200 and have had the same results for each resolution.

Thanks for another set of eyes on this.

If you don't mind, can you send the Custom QC patch to me so I can try this? It should most definitely work directly into the CI Movie Player.

Weird, right?
