Hello,

i am making a mixer of video, where also you can use it with live video from cameras, when the mixer plays with normal video everything its ok, when i am opening the camera of my macbook the video starts blinking..

Did you use an external camera or a build-in?
Because i have something like intrerruptions, so i am thinking thats my problem, but i dont have any compatible camera for mac to use it..

You ware sanding matrix from move and grab object to jit.scalebias at the same time, which resulted in blinking effect.
The trigger object sand bangs one by one,from left to right outlet.
My solution is not the best,but it was a quick one, because one of the object still gets unneccecery bang.
Just a sketch how would be better.
