The system displays a video for each of at least a subset of the participants and a user interface including a selectable video effects UI element. The system receives a selection by a participant of the video effects UI element. In response to receiving the selection, the system displays a variety of video effects options for modifying the appearance of the video and/or modifying a visual representation of the participant. The system then receives a selection by the participant of a video effects option, and further receives a subselection for customizing the amount of the video effect to be applied. The system then applies, in real time or substantially real time, the selected video effect in the selected amount to the video corresponding to the participant.
