Techniques are described herein for combining video frames of two or more real-time video streams into combined video frames of a combined real-time video stream for continuous presence. Video frames of at least two real-time video streams are combined into combined video frames of a combined video stream. The combined video stream is supplied to a video display for displaying the combined video stream. Each video stream includes video frames with subject and background images. The subject images of corresponding video frames of the first and second video streams are combined into a combined video frame of a combined video stream such that the subject image of the first video stream is positioned in an anterior portion of the combined frame and the subject image of the second video stream is positioned in a posterior portion of the combined frame.
