Instagram Now Supports LiveStream from desktops

Instagram now supports rtmp live streams for people with a professional account. mimo You all should add some new settings to the output that can allow us to scale down the 1080p to 720p to compensate for the IG vertical view showing my entire screen. I know I can change the resolution, but it just crops on Instagram when I go live, showing mostly the center of the screen. Can this be added as soon as possible because I plan to use it together with Facebook and YouTube really soon?
