Our new video add-on for SessionLinkPRO is now in beta test stage. You can try it here:
Just login with your regular username and password, select your video source and send a video link to the guest. You may use your webcam, or, if you want to stream your production video, you can use a capture device to grab the video from your DAW. Blackmagic cards like e.g. Blackmagic Intensity and some Canopus cards work well. You can also try to use a screencapture with Camtwist or XSplit.
