determining, for each part of multiple parts of the virtual 3D video conference, and by a first computerized unit, (a) a participant behavioral predictor to be applied by a second computerized unit during the part of the virtual 3D video conference, (b) one or more prediction inaccuracies related to the applying of the participant behavioral predictor during the part of the virtual 3D video conference, and (c) whether to generate and transmit to the second computerized unit prediction inaccuracy metadata that is indicative of at least one prediction inaccuracy that affects a representation of the participant within a virtual 3D video conference environment presented to another participant of the virtual 3D video conference during the part of the virtual 3D video conference; and

generating and transmitting to the second computerized unit the prediction inaccuracy metadata, when determining to generate and transmit to the second computerized unit prediction inaccuracy metadata.

12. The non-transitory computer readable medium according to claim 11 wherein the first computerized entity has access to a video of the participant, the video is acquired during the virtual 3D video conference; and wherein the second computerized entity has no access to the video.

13. The non-transitory computer readable medium according to claim 11 wherein the first computerized entity is an image analyzer and wherein the second computerized entity of a rendering unit.

14. The non-transitory computer readable medium according to claim 11 wherein the determining of the participant behavioral predictor to be applied by the second computerized unit during the part of the virtual 3D video conference is based on a behavior of the participant during a previous part of the virtual 3D video conference.

15. The non-transitory computer readable medium according to claim 11 wherein the determining of whether to generate and transmit to the second computerized unit prediction inaccuracy metadata is based on the effect of the at least one prediction inaccuracy on the representation of the participant.

16. The non-transitory computer readable medium according to claim 11 wherein the determining is executed by a machine learning process.

17. The non-transitory computer readable medium according to claim 11 that stores instructions for determining when the part ends and a new part starts based on the one or more prediction inaccuracies related to the applying of the participant behavioral predictor during the part.

18. The non-transitory computer readable medium according to claim 11 that stores instructions for sending a part end indicator to the second computerized entity.

19. The non-transitory computer readable medium according to claim 11 that stores instructions for sending to the second computerized entity, information about the participant behavioral predictor to be applied by the second computerized unit.

20. The non-transitory computer readable medium according to claim 11 that stores instructions for determining, by the second computerized unit, at each part, the participant behavioral predictor to be applied by the second computerized unit.

21. A method for predicting behavior changes of a participant of a virtual three dimensional (3D) video conference, the method comprises:

(a) determining, by a first computerized unit, a current participant behavior predictor, wherein the determining is based on an analysis of a previous video segment that captured a previous behavior of participant;

(b) calculating a current predicted behavior of the participant by applying the current participant behavior predictor on a current video segment;

(c) comparing the current predicted behavior of the participant to a current actual behavior of the participant to provide a comparison result;

(d) determining whether to generate and transmit prediction inaccuracy metadata, when the comparison result is indicative of one or more prediction inaccuracies; wherein the prediction inaccuracy metadata is indicative of at least one prediction inaccuracy that affects a representation of the participant within a virtual 3D video conference environment presented to another participant of the virtual 3D video conference;
