Bad-Practice: Include 'presentation / video production' as camera input in MS Teams Meeting + Teams Live Event

Via MS Teams Settings you have the option to configure an external camera as device. This can be used to include the video output signal from external mixer (e.g. vMix, OBS Studio) into a Teams Meeting or Teams Live Event, and then to spotlight it for all participants in the Meeting.
But be aware of a serious caveat with such setup. From Teams perspective, that video signal is regarded as the camera display of 'face of a participant'. And Teams will continuous process it for optimal contrast of 'face' against the background. As long as in the video production there is indeed only a face, there will not be a real issue. But in situations where there is not (only) a face in the video production, e.g. slides are presented, the mismatch with Teams understanding results inevitable that the slides are on occassion not sharp rendered but blurry. The correct way to include the produced video signal into a Teams Meeting or Teams Live Event is via 'Share Content'; Teams Meeting prioritizes 'screen / content sharing' above the local 'camera'.
Nice outline on this:
