mutli projection + isadora

I have two questions and perhaps people could help me.
I have screens opposite to each other, two projectors and one mac.
I have created two different mask 1&2 in photoshop ( representing sale 1 &2 of boat) and I have imported them in Isadora. Now I would like to project simultaneously on the two screens the same film but using the two different shapes, is that possible, if yes how could i do this?
Also i would like one film to start one screen 1 and then happening in screen 2. Is any one know how I could do this with Isadora? I will still have tow projectors and one mac.
thank you for anyone who could help me, because I am struggling and start to have grey hair...

hi,

if you have not already, you should ask @ the isadora user forum. i'm sure other users might find the solution useful too.

Hello,'
this is Marlon.
I assume that you are using only one computer, if that is the case:
I think that in Isadora or jitter you have to design and time your changes in two stages or windows. You have to program the synchronization ..The idea is that you create two outputs and design your changes or states.
The main issue is that you have to play it in a computer with two graphic cards to have two performance screens . I know that you can do this easily in a Mac G5 and also have more than two (because you can get until 4 xtra video cards). So you have your extended screens with possibility of having your desktop and two virtual screens. So, you place the stages or the windows there you your "choreographed" media outputs.
I know that there is a lot of people using this guy:
the matrox ( a device that creates more than one outut) with one computer.

If you have access to more computers you can connect the computers via tcp/ip or midi and network them to coordinate in their states.
Let me know if this is helpful.

(I knw that her in the network the is maya Ciarroci witha lot of experience in Isadora) and multiple outputs.

Hey there, Maya here.
As Marlon said above, you will need a computer that in some way can handle two separate channels of video (two stages). Either you have a mac tower with an extra video card or a laptop and a Matrox DualHead2Go. Check it out at the Matrox website. If you search the Isadora forum under Matrox DualHead2Go or TripleHead2Go you will find some information of how to set it up. Basically the device creates a extra wide desktop that equals two video screens. You then play your images to the same stage with two movie players and projectors but put their left orientation to 0 and 50 and their width to 50.
If you have a tower if two video cards you then will have two movie players and projectors but set to different stages. You will need to set this up under "video" in the preferences. This an easier but more expensive way to go. Good luck!
