An emergency call to all event organizers.
Please, no beamers in front of the stage.
The stage is for a speaker; They use the whole stage and need professional sound AND lighting.
I hear often; there is no light. Otherwise, the audience can not see the beamer. Stop that!
Put the beamer at the side of the stage. Or above. Never in the front. You know why? See the video.
