fredfish Posted June 2, 2011 Share Posted June 2, 2011 I'm looking for a tool which allows you to warp the output of a mac, in order to provide vertical and horizontal keystone correction. Is this possible within software? Link to comment Share on other sites More sharing options...

fredfish Posted June 2, 2011 Author Share Posted June 2, 2011 Quartz Composer. Having asked around a bit more, it seems that some older graphics cards supported keystone correction, but this functionality no longer seems to be available without expensive / overly complex software. Next time it might be easier to go for a barco Sh!t Shaper Screen Shaper. Link to comment Share on other sites More sharing options...
Andrew Edwards Posted June 2, 2011 Share Posted June 2, 2011 Qlab definitely supports a custom quartz render. The video upgrade from the free version is not particularly expensive. Talk to figure53, there might already be a qtz for it. Link to comment Share on other sites More sharing options...

Talk to figure53, there might already be a qtz for it. I can see that qlab has translation / scaling / rotation functionality, could someone tell me how to implement that custom render? Although I have used Qlab, Quartz is beyond my knowledge at the moment. Edit: I don't have the pro video features on this machine Link to comment Share on other sites More sharing options...

Well worth investigation. Is it then possible to do more advanced geometry correction through qlab in a similar way? I was thinking perhaps mapping on to curved walls, cylinders etc. It would certainly be much cheaper than many of the other hardware or software solutions.
