  contract camera movement

  Posted by Ali Brakat on June 10, 2018 at 2:35 pm

  Hi,
  I have a shot with camera banning like this one
  https://www.shutterstock.com/video//clip-5945381-virginia—october-2008-epic-large-scale-revolutionary
  now if I track the camera in 3d and want to use that tracking info to contract the camera movement so instead of the null following the point it fixes that point by moving the clip

  the purpose of this is to compose it in another clip so I want to get rid of the camera movement
  any ideas?

  You don’t need to get rid of the camera movement to compose with another clip. You can track the camera motion and then make the composited layer(s) follow the tracking data.

  yes that’s what I want to do
  when I track the 3d space I want the point that’s tracking the camera movement to be used to transform the clip to get rid of camera ban check this comp

  I am blending the shot into the comp so when there is a camera ban it’s visible if I can get rid of it perfectly it would be much better than keyframing the clip to get rid of the ban

  in other words, I want the soldiers to be walking on a still background be reversing the camera motion,
  What do you think?

  I don’t want to track an element into the clip but I want to use the clip itself as an element in my comp

  the movement of the background makes the blend visible and I can’t key it properly to be completely visible without a rotoscope which what I am trying to avoid 🙂

  So you want to stabilize the shot of the soldiers and composite it onto the other shot? To stabilize a shot in After Effects, you can use the Stabilize Motion button in the Tracker. Or you can track a point using the Track Motion button (or points), apply the track to a null object, and parent your layer to that null.

  However, in the panning shot you showed, there is only a small part that is in both the beginning frame and end frame. Taking out the motion would involve zooming in probably over 500%, which would make the shot unusable in many ways.
