  Lens Flare jerkiness??

  Posted by Mark Linthicum on June 10, 2010 at 8:25 am

  Any one know why AE is doing this to me??

  The lens flare source point is to stay on the tip of the star and the lens flare jumps around, i tried to make it not move on the X axis but it did not help. it still jerks from left to right.

  here is the image, if you go frame by frame you will see The circle on the lower left behind the text jumps around.

  Any insight would be appreciated.

  Thanks, Mark

  A few specific details will help us understand how you did this and thus maybe enable us to give some solutions. When you’re in a project, you know all details and you just want to solve the things that do not work, but remember we are not mind readers, remote viewers or AE diviners… so we have no idea how you set up your project unless you tell us.
  So- did you track the star corners and link the flare to that data or did you animate by hand?
  Is the footage progressive or interlaced?
  Any other details that may clarify the way you worked…

  It is not tracked, I just placed keframes in the timline evert few seconds to track the point. .
  The footage is progresive.

  Are the keyframes of your animation set to linear or bezier?
  If you have bezier this may cause the jitter- turn all keyframes to linear.

  Thanks for the help,

  I am using CS4, ProRes Footage upresed from DV

  I understand AE uncompresses any footage you import into it, so it should not matter the footage type. especially since this flare is not part of the image it is generated in AE and all looks fine with the exeption the movement of the lens flare.

  Thanks, Mark
