  problem tracking a flare effect to camera movement…

  Posted by David Lieberman on May 1, 2008 at 4:18 pm

  Hi,

  I’ve got a video clip which i shot of an alleyway and its a bit shaky… in the back of the alleyway i’ve added a glowing window. Its a solid layer with a sapphire lens flare added to it… i’v managed to make the layer move with the camera shake by parenting it to video clip (after i tracked it and all that) but my problem is that the flare doesn’t track with the layer…

  is there anything i can do to make the flare effect itself track or do i need to change the position of it frame by frame?

  thank you…

  thanx for the help.

  I’m not familiar with that plugin, but it’s probably just a matter of using a layer space transform expression like this:

  L = thisComp.layer(“your window layer”);
  L.toWorld(L.anchorPoint);

  Some variation of that, depending on how you have things set up.
