Changing the keyframe default settings
 
 
 

To change the keyframe default settings

  1. Select Edit > Preferences and open the 3D Tracking page.

  2. Enter the keyframe Step value. A step of approximately 15-20 keyframes is generally a good trade-off between computation speed and accuracy.
  3. Enter the Maximum keyframes. This value allows you to limit the calculation time regardless of the sequence size.
