A video conferencing server () receives and combines video streams captured by cameras of plural video clients () and generates immersive video streams () for delivery to and play-out by these video clients (). A cut-out module () in the video conferencing server () generates a foreground mask () for a video frame () received from a conferencing client (). A camera shake detector () determines a displacement vector () for a subset of features in the video frame (). The displacement vector () represents a two-dimensional motion of the subset of features between a background mask and a previous background mask for a previous video frame received from the same conferencing client (). A camera shake correcting module () applies a displacement opposite to the displacement vector () to the foreground mask () before use thereof in the immersive video streams () for conferencing clients (), and a signalling unit () generates a shake indication () into the immersive video stream () delivered to the conferencing client () whose camera is shaking.
