Copying Shift Channels
 
 
 

Using the Channel Editor, you can copy a tracker's Shift channel values and paste them into any other channel in any module. For example, you can copy jitter values to the X and Y position channels of an axis to add realism to a static scene, or to a channel to add noise.

There are two Copy buttons in the Stabilizer. One takes the aspect ratio of the clip into account and the other one does not.

The coordinate system that the Stabilizer uses for mapping pixels on the image differs from the system used by other modules. In the Stabilizer, the pixel with coordinates (0,0) is in the lower-left corner, while in most other modules it is in the centre of the screen. When pasting shift curves to the channels of an axis, use the Copy button that takes the aspect ratio into account. Since this button also accounts for the differences in pixel coordinates between modules, it ensures that the values are mapped properly.

To copy and paste a shift channel:

  1. In the Channel Editor, open the folder of the tracker whose shift values you want to copy.
  2. Select the X or Y Shift channel, or the entire Shift folder to select both X and Y Shift channels.
  3. Click one of the Copy buttons, depending on whether or not you want to maintain the aspect ratio.
  4. If necessary, load the clip to which you want to apply the Shift values into the appropriate module.
  5. Open the folder of the channel to receive the copied shift values and select the appropriate channel(s).
  6. Click Paste.
