I am sure you have used video spot light in Skype for Business and loved this feature. But it made people crazy when they heard its not available in Microsoft Teams (Are you kidding ??), Yes for now its not available in Teams. This feature is very useful in several scenario, like you are delivering lecture with students and want to freeze the video (trainer/teacher) with spotlight (Of course you must be presenter in meeting to use spotlight), Once the individual identified as the spotlight will be the main video shown to all participants. This applies to PC, Mac, mobile, and Microsoft Teams room systems.
Microsoft heard your voice and now its around the corner and going to be release by SEP 2020 for GA (General Availability).
Stay tuned ! 🙂
