While it is possible to use the "screen-share" feature in Zoom (or other video-conferencing platforms) for "in-classroom screenings" of streaming media, is not recommended by the Library. It will likely result in poor audio and video quality for students viewing the material and could stress internet connections. Additionally, some streaming platforms apply copyright protection to their content which prevents any images or sound being shared using the "screen-share" feature.
Ideally, a permalink to the streaming media would be shared and the students could watch the video prior to the start of class discussion, so that they may view it on their own time without having to worry about quality or computer/internet limitations. For synchronous "in-classroom screenings" the recommended procedure is to direct students to view materials on their own, in a separate tab or window, with their Zoom audio muted, and then return to the main meeting for the continuation of class.
"Streaming" multimedia (video & audio) allows the user to begin viewing video clips stored on our server, without first downloading the entire file. After a brief period of initializing and buffering, the file will begin to stream - or play - in real time. Your picture quality will be determined by your available bandwidth (download speed) and computer processor speed. Users with older processors and slower modem connections will have more dropped frames and pixelization.
