* Under Broadcast, select Broadcast Settings. For the Encoder Preset you will need to edit an existing preset until it looks like this:
For Audio I chose MPEG-4 Audio and Best Quality. It won't let you save at higher than 44.1 sample rate, not 48. Odd. Save the Encoder Preset under a reasonable name, then select it as the active Encoder Preset. I called it "720p23.976". Set the Destination to "Record to Disk" and choose the file location. This includes a default filename: check "Auto increment filenames" and it will add a numeric suffix for each file recorded. Make sure that all the stuff you just set up appears in the window at the top of the panel and then click Save. In fact, all you have done here is to set up an Encoder Preset, because if you had wanted to set WC up for broadcast live streaming, this would not be the settings you would use. To set the Record parameters, click the little hard drive labelled "Record" in the top left of the WC main window and do most of the same thing again, except for the fact that you simply have to select the Encoder Preset that you created earlier. When you click this in future, it will start capturing to disc.

Now we come to the tricky bits. Wirecast has five layers on which you can place content/sources. The default layer is #3 and as you currently have the Layer Panel visible, you will probably see that the only source there is is your Intensity Pro card on that layer. You can rename the layer to something more appropriate, such as "Video" by double-clicking on the label.
