  Perspective Corner Pin Tracking and obscured points

  Posted by Terrym on February 19, 2007 at 11:36 pm

  On my shot I am walking to the left and the pole shown here ( https://img85.imageshack.us/img85/5981/untitleddddddddiy1.jpg ) obscures the tracking points in my shot. When they do this the tracking points go to hell and my box goes completely out of whack, then goes back to normal after the pole passes.

  I am looking for a way to delete all the key frames while the pole passes over a side and so it will draw a straight line in between the left over key frames for the corner pins. Right now it will not do that for some reason and no matter what readme or help file I look at I can’t find out how to do this.

  Right now I have the banner opacity key to 0% while the pole passes over a side but I don’t want to do this, thanks for the help!

  Try to track up to the point where the pole gets in the way and then stop tracking and move the CTI to after the pole stop obscuring your track points. Then put the track point into place again and finish tracking.

  This will leave blank tracking data in this range, but it will interpolate and you can fix the bounce by hand.
