Tutorial: How to Composite PowerPoint and Talking Head Video in Telestream Wirecast
Any time you produce a webinar that's got PowerPoint and a talking-head video, it's helpful to present them in the same video frame. This tutorial explains how to composite these two sources in Telestream Wirecast.
Adding the Audio
To add the audio, I click the plus (+) sign in the lower-left corner of the Editor, and then click the HDMI Input B-1 in the media panel in Figure 9 to select this audio input. And then I’m done.
Figure 10 (below) shows the new composition we just created on the far right in the media elements panel below the program window. To take that live I click it, press the Go button, and now we’re live.
Figure 10. And now we’re live.
So I think this layout is very effective for showing both PowerPoint slides and a talking head video, and now you know how to produce it in Telestream Wirecast.
