     \item[Translation search steps] Ideally the search operation would compare the translation block with every other pixel in the translation search radius. To speed this operation up, a subset of the total positions is searched. Then the search area is narrowed and re-scanned by the same number of search steps until the motion is known to $\frac{1}{4}$ pixel accuracy.
     \item[Block X, Y] These coordinates determine the center of the translation block based on percentages of the width and height of the image. The center of the block should be part of the image which is visible at all times.
     \item[Maximum absolute offset] The amount of motion detected by the motion tracker is unlimited if this is $100$. If it is under $100$ the amount of motion is limited by that percentage of the image size.

-    \item[Settling speed] The motion detected between every frame can be accumulated to form an absolute motion vector. If the settling speed is $100$ the absolute vector is added to the next frame. If the settling speed is less than $100$ the absolute vector is downscaled by the settling amount before being added to the next frame.
+    \item[Settling speed] The motion detected between every frame can be accumulated to form an absolute motion vector. Settling speed determines how fast the accumulated translation fades away, and the image resettles to its actual appearance. If the settling speed is 0\% the total absolute vector is added to the next frame. So every frame that is processed accumulates the whole motion of the past. If the settling speed is 100\% the absolute vector is cancelled completely, adding no past translation to the next frame. If the settling speed is intermediate between 0\% and 100\% the absolute vector is downscaled by (100 - settling amount) before being added to the next frame.

     \item[Track rotation] Enables rotation operations. The motion tracker tracks rotation in the master layer and adjusts rotation in the target layer.
     \item[Rotation block size] For rotation operations a single block is compared to equally sized blocks, each rotated by a different amount. This is the size of the rotation block.
     \item[Rotation search radius] This is the maximum angle of rotation from the starting frame the rotation scanner can detect. The rotation scan is from this angle counterclockwise to this angle clockwise. Thus the rotation search radius is half the total range scanned.
