Video Filters
Scale
Adjust the Scale slider to change the size of the keyed image. Image scaling always
preserves the correct aspect ratio of the image. A value of 100 scales the image so it
fits within the video frame and fills the frame horizontally and/or vertically.
Offset
Adjust the Offset slider to change the position of the keyed image. Higher values
move the image further toward the center of the video frame. A value of 100 positions
the image at the center of the frame.
Notes
No notes.
