Sharpen Edge
Enhances the image contrast around object edges. Some codecs blur the video image, so this
filter can counteract the softening effect of noise removal or blurred source material and increase
the perception of sharpness in the image. When used to an extreme, the output media file can
look grainy.
The Sharpen Edge filter contains a single control:
•
Amount: Sets a sharpen setting between 0.0 and 100.0.
Text Overlay
Superimposes text onto the image. This is a useful tool for stamping other relevant text
information onto your output media file.
The Text Overlay filter contains the following controls:
•
Position: Positions text in the image. Choose from any of 13 positions such as Center, Lower
Left, Lower Left - Title Safe, and so on.
•
Alpha: Sets the text opacity. Choose a value between 0 and 1. A value of 0 makes the text
completely transparent, and a value of 1 makes it completely opaque.
•
Overlay Text: Type your text here.
•
Text Color: Click the color well to choose a text color from the Colors window.
•
Select Font: Click this button to open a window for selecting font, style, and size.
