Optical Stabilizer

The BCC Optical Stabilizer filter enables you to quickly and easily
stabilize shaky video footage, such as clips that were shot with a hand-held
camera. The Optical Stabilizer uses optical flow technology to analyze every
frame in the source clip to determine the movement of the camera and then
adjusts the position, rotation and scale of the clip to compensate for the
unwanted camera movement. Depending upon filter parameter settings the motion
in the clip will either be smoothed or completely locked down. Unlike many
image stabilization tools, the BCC Optical Stabilizer does not require you to
set and keyframe user-defined tracking points, which is very useful for images
where point tracking data is unreliable.

Because the very nature of post camera image stabilization causes the image to
be cropped, this filter includes post image stabilization options to fill the
blank areas around the of the frame, such as:

  • Repeating pixels along the cropped edges,
  • Mirroring the image along those edges,
  • Filling them with solid color
  • Leaving them transparent. 

An autoscale function is also included in the filter. The Auto Scale function,
which is enabled by default, automatically transform scales the image so that
it fills the frame across time. Also included in the filter are seven user-
selectable transform scale algorithms, which ensure optimal post-transform
image sharpness.

Note that Optical Stabilizer is designed to be applied to individual clips
without cuts.  If you have a “compound” clip that contains multiple cuts you
should first split the content into separate segments for each cut and apply
Optical Stabilizer separately to the individual segments.  Similarly Optical
Stabilizer is not designed to be applied to Adjustment Layers or Precomps that
span multiple separate clips, but instead should be applied separately to each
individual clip.
