NCast Presentation Recorder Reference Manual
Once the frame is defined, the next step is to check for correct aspect ratio.
4.3.2. Set Aspect Ratio
The aspect ratio of an image is the visual width divided by the visual height. For most computer systems
“square pixels” are displayed, so the aspect ratio of the image is the pixel width divided by the pixel
height. In video systems, however, often “non-square’ pixels are displayed and the aspect ratio differs
from the pixel width to height ratio. The Frame Size (see 4.3.1. above) only determines the pixel
dimensions of an image. For proper display the aspect ratio must be specified and used to render the
final image.

4.4.1. PIP
If the “PIP” window is enabled, its (X,Y) placement and (W,H) dimensions are overlaid on the frame.
Typically this might be in the upper-right or lower-right corner of the frame. The PR-HD Series user has
the option of determining if the PIP window obscures any portion of the Main window. It can be placed on
top of or outside of the Main image.
4.4.2. PIP Border
If this control is selected a small border is drawn around the PIP window.
