Canvas Size
The first menu item in the Output menu is Canvas Size. When Output > Canvas Size is
selected, a drop-down menu with various canvas sizes is displayed allowing you to
select the canvas size you want. You can also select Auto. This automatically sets the
canvas size to the highest resolution that was selected when the encoder was chosen.
Note: Canvas size selection 1080p Anamorphic (1440x1080) is a narrower (1440)
display stretched to display as 1080.
There is also a Custom option that enables you to set the canvas width and height.
Wirecast can manage a wide variety of input sources, enabling you to have several live
camera sources. However, really high-quality video sources can cause more harm than
good. For example, an HD camera feed into a Wirecast canvas that is set to HD
resolution and then broadcast out in HD, requires a lot of work for the graphics
processor. If the frame rate starts to drop but the CPU usage stays steady, it creates a
bottleneck. The solution is to reduce the frame size going through Wirecast. Therefore,
there is no need to bring input video in at HD resolution if Wirecast is streaming out a
lower resolution.
