  Better 3D Camera Tracking?

  Posted by Callum Morrison on March 21, 2016 at 11:16 pm

  I am using the 3D camera tracker in AE on a shot where a lot of snow is present. As a result there is often some ‘slipping’ of the camera when I try to track it.

  Is there a good way around this error in tracking? I am using 3D stroke for my effect, which uses the default AE camera – simple position tracking is not an option.

  Would it be worth looking into Mocha?

  Example shot: https://www.youtube.com/watch?v=dLPuWQYGc6o&feature=youtu.be
  With track points: https://www.youtube.com/watch?v=pcgQuUGKi8M&feature=youtu.be

  The slip is pretty minimal, but noticeable. Look at the top right light streak around 6 seconds in.

  Any help is appreciated, thanks!

  Ok,

  To get an idea I assume I just want to make the footage as detailed as possible? Add sharpness and contrast to make edges more defined?

  Cheers

  Another possible approach is to smooth the results.

  Apply the smooth expression to camera position and/or point of interest.

  Messing with the original video didn’t seem to work; it gave track solving errors.

  I’ve ended up messing about with the smooth expression and I feel that what I have now – ‘smooth(1,11)’ on position and ‘smooth(0.5,1) on orientation works pretty well. I might tweak it a bit more but it certainly seems to be the solution! Cheers!
