A Question about Expressions
I pick-wipped a position of a lens flar to the Position of a Null Layer (Tracking Data).
NOw, the Flare is following the shot in the right way, but unfortunately the beginning position of the Flare is wrong. Where and How do I have to ad the offset x and y co-ordinates to reposition the flare?Thanx a lot.

You could for example add the following to the expression generated by the pick-whip:
+value
This means that the original value of the flare position will be added to the pick-whipped value.
This way you can easily change the original value so that it matches your needs.Bartek Skorupa

Tried it, it’s a rather difficult, cause it is adding to existing value – it involvves quiet a bit trial and error. I remember, there’s just some information you can ad to the x and y axis to shift it a certain amount of pixels.
