thanks all for the feedback about this issue. now i have a better overview of what I might be dealing with.

I am also working on a project like this (with thomas grill, who solved many problems before I even thought of them...). in principle synchronisation works fine. now your may ask why do other people pay so much money for expensive hardware? the problem lies in details: first resolution: for some cases you want to go with the highest available resolution 1080p (and in the future even more), and suddenly you will see small appearance of jitter, mostly because quicktime is different inside a quicktime player and outside quicktime, also because in most cases you have to convert color formats. then, compensating a drift without losing frames is very tricky. from my experience so far, Pd solutions only work up to 720p and only if you use a drift compensating algorithm - sending a bang for every frame over the network always causes jitter (although you may not notice). It is no big effort to try a pd version and see if you are happy with it. marius.

hi
I need to have several video outputs that run in sync. A friend who works in a art exhibition space told me there would be couple of solutions for this but both involve buying pretty expensive equipment like special DVD players.
I thought then that a solution for this issue could be to have several computers on a local network playing video (with GEM) and synchronise them via OSC. But I dont have any experience doing such a thing, never used OSC for anything similar. Also I dont have a clue about how to synchronise together videos.
Has anyone done anything similar? any experiences to share?
thanks!
