this is confusing me because depending on what was copyrighted is legal live. I know this because I spoke with an intellectual copyright lawyer. He has worked with TV shows. He told me that anything airing live that is an audio recording/cover song etc is exempt from copyright because LIVE broadcast doesn't need have a license. It's only when you re air or re play it. SO why YouTube is saying you can't have copyright when it's live is beyond me. Periscope and Facebook Live was sued once by Sony and the judge tossed the case out saying that because it was live it was fair game. The only thing you can't do is say hold your phone up to a movie or TV show and stream it.
Here is a section from Bonelaw Law website
"Typically, when a musical work is used in timed synchronization with video images, the user must obtain an additional license from music publishers; this license is referred to as a synchronization (“synch”) license.[9] Synch licenses can be expensive and time consuming to obtain. This is because synch license fees are not set by statute. Rather, synch fees are negotiated based on a variety of factors making the fees very unpredictable. Additionally, it is possible for a single song to have multiple songwriters and multiple music publishers, resulting in many hours of negotiations. Fortunately, as long as the video of the concert performance is streamed live, no synch licenses will be required. However, content creators and distributors need to be aware that synch licenses will be required if they desire to make videos of the musical performances available to the public after the live stream, whether in archived form, on their website, or for sale or distribution.[10]"
The only thing you have to pay for is a Performance Rights license which YouTube already pays for. This has been stated in hundreds of music companies like ASCAP, BMI and Harry Fox.
