Abstract

Method for producing a produced video stream (PR), comprisinga) capturing a first primary video stream (PV) visually showing a first user (122,122") and a second primary video stream (PV);b) automatically producing the produced video stream (PR) based on the first primary video stream (PV) and the second primary video stream (PV);c) down-sampling the first primary video stream (PV) and the second video stream (PV), thereby achieving a first shadow primary video stream and a second shadow primary video stream;d) automatically producing a produced shadow video stream based on the first shadow primary video stream and the second shadow primary video stream, the automatic producing being based on automatic production decisions corresponding to decisions used to produce the produced video stream (PR); ande) storing the first shadow primary video stream, the second shadow primary video stream, the produced shadow video stream as well as information identifying the automatic production decisions.
