Layers don't be synchronize withe the same cue
in MAIN
Hello,
In my project I use tow projectors and I project the same image in the same time in this tow projector which are superposed (to have more luminosity..)
So, do that I simply duplicate layer and move one in the first projector and the other layer to the seconde one in the second projector. But some time happen, when the cue come, they don't start in the same time and so I have and my tow images are completely unsynchronized (about 0.5seconde). And into a sceen of 9,6m / 5m it's a big problem in live!
any idea why it's happening, Or other idea how to project the same thinks in tow different output without using mad mapper, and I need to map differently this tow projectors so I can simply spleet one output...
Thanks

Be sure you click on the "Optimize" button on the top-left corner, and check that your codecs are ok for realtime.
Then check that your drive is fast enough to playback all your movies at the same time.
If your cuepoint is in the middle of a movie, this is not a good practice for the reasons explanined in this thread. It's better to split your movie at your cuepoint (despite we're working at a better solution).
Lastly, a good practice to use the same content at two different position, is to use a "copy layer" : see this tutorial.

You can use 2 instances of millumin.
instance 1 : create your show just for one screen and active syphon output !!!
instance 2 : use syphon of the first instance and create a copy layer. So you can map like you want !!!
If the first instance doesn't work, the problem come from the files. A SSD is better if you have a lot of files in same time
Bye
If you have the same problem on 2 different computers, your graphic card may have a problem.
You should test your project on another computer, to see if the problem is related specifically to your machine. Run a test with simple "copy layers" (such as explained in this tutorial, but without After Effects).

Do you use "copy layers" ? It's the best way to keep all your content synchronized amon several layers.
Please watch this tutorial for more information.

First of all, you cannot create a "millumin show with 50fps base" : in fact Millumin is synchronized to vertical refresh rate of your monitors (typically 50hz or 60hz).
Also, movie rate can be different from monitor refresh rate. For example, movies at 50hz VS monitors at 60hz : in that case, some a +- 1 frame difference could occur. But it's very rare, as this kind of conversion won't be necessary for movies at 25 or 30hz (the monitors is fast enough, 50 or 60hz, to playback all frames).
Lastly, Millumin uses Apple libraries to playback movies : it's more efficient to be in 64-bits mode, so Millumin can use AVFoundation libraries. If you have OSX 10.8, you can activate 64-bits mode in the Preferences (if you don't have this option, be sure to update Millumin to the latest version, which is always recommanded).
Let us know the progress.

Millumin is software only. We do not sell hardware+software such as Watchout or Pandora Box.
"Hardware framed-locked" graphic card are very specific, and only a few models are available(mainly NVidia Quadro and ATI S400). Unfortenatly not the ones for Mac (except FirePro I think, but such genlock is not available on OSX as far as I know).
We'll try to reproduce your issue.

Thx for investigations.
@tom: have you tried to scale and position both clips on only one of your displays and then film the screen with your camera? Because even the same type of displays can produce frame delays.
And could you try to use 720p50 "time code test file" instead of 1080p50? If QuickTime does not play your clips at stable 50fps it seems that your machine is not strong enough, and if this is the case Millumin will have the same problem. With the Mac Pro I can play easily 8 ProRes 1080p50 with stable fps.
@philippe: to compare Millumin with watch out/pandoras box is not fair, as you already said. And there is no need for me to sync machines at this moment. I just want to have 5 (6) frame synced outputs out of one nMac Pro.
For future Millumin v2 with smpte feature it would be great to have frame locked playback with more than one machine and perhaps there is an option that Millumin can double check the playback position and compare the position of the "play heads" every frame and then readjust/respeed the different machines to guarantee the sync.
Thx
Ok we use the same system, good base for testing
I'm still on 10.9.5.
Did you watched those two tv clips next to each other on one screen?
I tried SwitchResX for smaller setups without a Matrix.
But EDID management with a DVI cross point is much easier. Especially if your Mac forgets which screen is display 1,2,3,4,5,6 you route the ins and outs via the cross point instead of playing the screen assignment quiz in Millumin
Did you do that TC video file test?
Anyone interested in my TC ProRes file?
