We love the Epiphan Pearl! It is revolutionizing live event streaming, especially for education, lectures, sales training and corporate presentations. You can capture up to 4 HD sources at once, including output from your laptop. This makes it great for those needing to integrate powerpoint, screen grabs, excel, charts and graphics into your presentations. When it comes to encoding and streaming, Pearl does a fantastic job as well. In this tutorial you'll see just how simple and easy it is to enccode directly to YouTube Live.
