  script to move on y axis

  Posted by Valerie Morrison on June 14, 2009 at 3:49 pm

  Hey everyone,

  I’ve got 6 tracks each with 1 video event. Each of these videos have several keyframes on 3d alpha track motion (hope I’m saying this correctly).

  I want to move every video (at every keyframe) on the y-axis. Basically I need to move the videos (which are like PIPs) so that they are centered vertically on the screen. I was hoping to use a quick script to loop through all of the tracks and just change the positionY = 0 for all keyframes. I’ve found a few things while doing research, but nothing that I find simple enough.

  Can anyone point me to a simple 3d track motion looping script?

  Thanks

  Valerie

  Hi Valerie,

  This script will set all of your track motion keyframes so that the Y value is zero. Just cut and paste into a file named ResetTrackMotionY.cs and place it in your Vegas script menu folder.
  
/**
 *       Script: ResetTrackMotionY.cs
 *  Description: This script will reset all of the TrackMotion keyframes Y values to zero
 *       Author: John Rofrano
 * Last Updated: June 14, 2009
 **/

  using System;
  using Sony.Vegas;

  class EntryPoint
{
   public void FromVegas(Vegas vegas)
   {
      foreach (Track track in vegas.Project.Tracks)
      {
         if (track.IsVideo())
         {
            VideoTrack videoTrack = track as VideoTrack;
            if (videoTrack.TrackMotion.HasMotionData)
            {
               foreach (TrackMotionKeyframe keyframe in videoTrack.TrackMotion.MotionKeyframes)
               {
                  keyframe.PositionY = 0.0;
               }
            }
         }
      }
   }
}

  This script only works in Vegas Pro 8.0 or 9.0.

  Thanks John, that’s exactly what I was looking for. I can use this for the basis of other changes to rotation and position, rather than having to do things manually.

  Thanks so much.

  > I can use this for the basis of other changes to rotation and position, rather than having to do things manually.

  Yes, the other positional attributes are:
  
keyframe.PositionX
keyframe.PositionY
keyframe.PositionZ
keyframe.RotationX
keyframe.RotationY
keyframe.RotationZ
keyframe.OrientationX
keyframe.OrientationY
keyframe.OrientationZ
keyframe.RotationOffsetX
keyframe.RotationOffsetY
keyframe.RotationOffsetZ

  Glad I could help.

  I see that John came through with a script, but honestly I don’t think you need one. To make several tracks move in unison, all you need to do is insert a new track above them, make each of those a Child of the new one, and then set keyframes for that first one (called the Parent). The rest will move as a group controlled by this Parent track.

  The button to make one track the child of another is at very right of the track header and looks like a bent arrow.

  Rob, Good point. I was going to mention that but after re-reading the post I felt that the OP was really trying to adjust things and not move them dynamically. But you are correct… the easiest way to move them in unison with with a parent track.
