  Create a Shape then track it

  Posted by Colin Shamrock on November 2, 2009 at 11:13 pm

  Hi,

  I’m trying to something simple. Yet I fail. Please please please can someone help my, this is driving me bonkers…..

  What I want to do is create a circular shape around somebody’s hand for example. Then I want to track the hand and apply the tracking data to the position of the shape.

  First, I tried adding a shape wipe to V2 over the background on V1. Scaling down the wipe means I get a decent circle. But I cannot track it, and applying another effect with tracking parameters to it, e.g. a 3D warp, obviously moves the image on V1 too. Well that’s not what I want, so I try again.

  Create a circular shape with the paint effect, then track it. Sounds good. Tracking works. But when I create a circle and choose Outline as a mode, I don’t really get a nice circle. Far from it. Cannot make the border thicker. I can create a solid and then a second shape that erases the parts I don’t like, so I get a circular shape with a nice border, but that is a bit cumbersome.

  Does someone have any idea on how to do this? I’m on a Media Composer 3.0.4, btw….

  Any help is greatly appreciated and will give me back my sleep.

  Cheers,
  Colin

  How about drawing a circle in the Title Tool, then track that to the hand?

  Hi,

  thanks, that works. First I thought it wouldn’t, but of course if you promote a title to 3D, you get the tracking category in the effect editor.

  Many thanks for your help, that saved me from a lot of keyframing!!!!!

  All the best,
  Colin
