For video applications, a method for dynamically switching from a current ROI to a target ROI is disclosed, wherein the target ROI only includes active speakers. Advantageously, if the target ROI crops a non-speaker, then the target ROI is expanded to include said non-speaker. Transitioning from the current ROI to the target ROI may be achieved based on a cutover transition technique, or a smooth transition technique. The cutover transition technique achieves the change from the current arrived to the target ROI in a single interval, whereas the smooth transition technique achieves the change over a number of intervals, wherein a percentage of the total change required is allocated to each interval. A system for implementing the above method is also disclosed.
