About the Input Video Aspect Ratio
The V-440HD is capable of simultaneously handling video images in
differing formats and with different aspect ratios (the ratio of the
vertical and horizontal dimensions). The V-440HD outputs video by
scaling (enlarging/reducing) the input video so it matches the
output format.
* For more on output formats, refer to "Selecting the Output Format" (p. 26).
You can select the type of scaling for the video with the following
procedure.
1.
Press the MENU button.
2.
Select "2. HD/RGB Input."
3.
Press the ENTER button.
4.
Select the channel in which you want to make the settings
from "HD/RGB ChA/B"–"HD/RGB Ch4."
5.
Press the ENTER button.
6.
Select "5. Scaling Type."
7.
Press the ENTER button.
8.
Select the scaling method.
Select the most suitable scaling type from the menu, selecting
from "Full Scale," "Fixed Aspect: Letter," "Fixed Aspect: Crop,"
or "Manual." The initial setting is "Full Scale."
