Each parameter can be set to a value between 0.0 and 5.0. A value of 0.0 turns off the
parameter, and a value of 5.0 applies the strongest possible transformation. The higher
you set each parameter, the more camera motion is compensated for in that axis.
For example, if you want to remove horizontal, vertical, and rotational movement, you
should set the Translation Smooth and Rotation Smooth parameters to a value above 0.
You may need to experiment to see which values steady your shot the best.
Correcting Black Borders Around Your Clip
When the SmoothCam filter compensates for camera movement, it translates, rotates, or
scales your clip in the opposite direction, potentially causing a black border around the
edge of the clip in the Canvas. To correct for the black border, the SmoothCam filter
determines which frame in your clip requires the most scaling to remove the black borders
and then automatically scales the entire clip by that amount.

Factors That Affect SmoothCam Scaling
You can control how much the SmoothCam filter scales your clip in several ways,
depending on the effect you are trying to achieve:
• Reduce the Translation Smooth, Rotation Smooth, and Scale Smooth parameter values
so that less motion correction is applied. This means that there is less black around
your clip, so less scaling is required. Try to adjust these parameters to find a balance
between acceptable scaling and adequate motion compensation.
