Several properties in this tab can help you achieve a better track. Here are some
important ones:
• Number of Features: The amount of automatic tracking points created by
the tracker. If you increase this, reduce Feature Separation.
• Detection Threshold: The higher the number, the more precise the tracker
has to be in finding trackable points.
• Feature Separation: The higher the number, the farther apart the tracking
featureshavetobe.IfyouincreaseNumberofFeatures,reducethisvalue.
• Track Validation: This setting tells Nuke whether the camera is handheld
or Free Camera, meaning a free-moving camera, or if it's nodal or Rotat-
ingCamera,meaningacameraonatripod.TrackValidationvalidatesthat
the tracks are correct.
