Exemplary embodiments relate to techniques for applying media effects to a video stream. For example, media effects may be applied and/or altered based on input from viewers or participants in the video stream. Changes to the media effects may accumulate based on the inputs. In another example, viewership numbers or engagement with a user applying a media effect may alter the media effect. In a broadcast context, actions of the broadcast audience (e.g., as measured by polling) may affect the broadcast and hence the broadcaster. Object recognition and/or people recognition may be applied to cumulatively alter the media effects in an augmented reality context.
