Working with the Motion Stabilizer
505
Advanced Tab (Motion Tracker)
The Advanced tab allows you to fine tune the motion tracking for more accurate results.
You can often adjust a failed tracker by increasing the Failure Threshold value. Typically the
Failure Threshold accuracy should be at least 90 percent for an accurate result. It is also
recommended that the Failure Threshold is close to or slightly below the Auto Update
Threshold value.
Parameter Description
Pre-Blur option Select to apply a blur to the image. The blur temporarily
reduces noise in the footage that can help produce better
tracks.
Track in Reverse
option
Select to track backwards. This is useful if the area you want
to track grows larger as the effect proceeds or if the area is
off screen at the beginning of the effect.
Input Channel menu Select an option to determine which channel in the Source
track is used to calculate data. The option includes:
Luminance, Saturation, Red, Green, Blue. Experiment to
see which channel produces the best result in your effect.
Saturation in particular may be useful if the lighting in the
effect changes over time.
Sub-Pixel Accuracy menu Select an option to estimate motion to an accuracy of a
fraction of a pixel. Select the accuracy you need up to 1/256
of a pixel.
Smaller fractions provide higher accuracy but may take
longer to estimate.
