Picture vibrating

[mit1]

Recently when I'm hosting a meeting my screen begins this awful vibration. My picture fades in and out..and exhanges with other people in the meeting. My video is the only one that does it. HELP!

Following this question. Mine does this also. I also see myself freezing and my movement jerks back and forth. The audio is fine during this time. Please help!!
