Some transitions accept addition arguments through the filter property, for example, you can set the location of suckEffect using
...
CAFilter* filter = [CAFilter filterWithName:@"suckEffect"];
[filter setValue:[NSValue valueWithCGPoint:CGPointMake(160, 240)] forKey:@"inputPosition"];
transition.filter = filter;
...
