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 set to HD resolution, 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.

Keep in mind that resizing down is good but resizing up reduces quality. As a rule, you

should try to keep your resolution as constant as possible from source to output. There

is no benefit from using an HD camera if you’re only broadcasting a low resolution

stream. This only increases the work your computer must do without any increase in

output quality.

Virtual Camera

Wirecast enables you to present the output of Wirecast as if it were a camera (a virtual

camera), allowing it to be automatically detected by other applications when they are

launched. To setup Wirecast as a virtual camera, select Broadcast > Virtual Camera Out,

then select the output resolution to use. You can also select Match Canvas to cause the

resolution to be the same as the current canvas size.
