RealShow is a smart tool to record and share your PowerPoint slides with
actual video presence and in-depth audio-visual guidance and illustrations.
RealShow has a very simple interface that helps presenters to integrate their
valuable slides, freehand typing and drawing, and video narration into one
single peace of video. RealShow coordinates webcam video of the presenter
with the PowerPoint presentation and saves the record as a single and
compressed video file in WMV, AVI, FLV, or SWF format. (in Business and
