This effect adds blur to the image; it copies the image multiple times, shifts
the the copies in a given direction, then combines all of the images together to
simulate a directional blur.
You can adjust the following settings for this effect:
Angle setting. This defines the angle in which the
images will be shifted. 0 indicates the top as the start point and values
greater than 0 move the start point clock-wise, and images are directionally
blurred as follows:
0 indicates the images are being blurred to right.
25 indicates the images are being blurred to bottom.
50 indicates the images are being blurred to left.
75 indicates the images should be blurred to top.
Blur defines how far the images will be shifted to create
the blurring effect in the resulting image.
These settings for this time lapse software effect (12 as the blur
setting) move the blurred image a bit to the bottom (25 as the angle setting).
