  Real world units

  Posted by Jake Smith on January 14, 2011 at 1:39 pm

  Hi Everyone,

  Is there a way to figure out real world units in AE? For instance, 100px = 1ft. I pretty sure there is not, but I wanted to get a second opinion.

  For instance, let’s say you have a piece of footage and you know your subject is 3 feet from the camera. Now you need to create a camera that would be 3 feet away from from your center point in Z space.

  Cinema has the ability to use real world units in v12 so I created the camera in there and imported it. I was getting a number around 90.5px = 1 foot. This is a fine work around, but just curious to see if anyone else had some information on the problem.

  Thanks!
  Jake

  Also, the real world distance and the distance as viewed would vary a lot dependent on the field of view of the camera. Different lenses will cause things to appear very different depending on the angle. AE is not a 3d program so again, as Dave said, no.
