Iterations: Choose the number of noise-smoothing passes
(between 1 and 4) from this pop-up menu. For instance, if
you choose 2 passes, the noise-removal algorithm is
applied to the media file twice. The file resulting from the of
first pass is used for the second pass, and so on, so that
the more times a pass is performed, the fuzzier the image
becomes.
Algorithm: Choose a noise-smoothing algorithm from this
pop-up menu. Choose Average to modify each pixel’s
color by taking an average of pixels around it, including its
own color value. Choose Replace to modify each pixel’s
color by taking an average of pixels around it, while
ignoring its own color value. Choose Merge to modify each
pixel’s color by taking a weighted average of surrounding
pixels and itself (with the pixel’s own color value given
greater weight).
Sharpen Edge: Sets the contrast around object edges. This
effect can counteract the softening caused by noise removal
or blurred source material and increase the perception of
sharpness in the video. However, note that too much of this
effect can make video look grainy. Drag the slider to set
sharpening between 0.0 and 100.0. (You can also double-click
the value and type a new value.)
Text Overlay: Superimposes text onto the image. The Text
Overlay effect contains the following properties:
Position: Choose a position for the text overlay from the
pop-up menu, such as Center, Lower Left, Lower Left–Title
Safe, and so on.
Alpha: Drag the slider to set the text opacity between 0
(completely transparent) and 1 (completely opaque). You
