Cropping tab
Use the Cropping tab (Figure 28) to enable and disable cropping and set the desired cropping
rectangle. Cropping means removal of unwanted video around the edges of the incoming image. For
example, if the incoming video is letterboxed, with an aspect ratio wider than 4:3, you can crop
away video at the top and bottom of the image and capture just the active portion. The Left and
Width controls are used to crop the left and right sides of the video.
Note: This type of cropping is different from the final desired Display size that is usually set by the application software that
negotiates with the driver to deliver the desired output.
The Display size is the size of the Osprey graphic in the dialog box. It is used to understand the size
ratios versus the video appearance between the Reference size (incoming signal), what you see in
the dialog box (Display size), and what appears at the client, i.e., such as Windows Media Encoder.
