Video production can be a fantastic addition to your broadcast
Back in the day, using videos in your broadcast were a struggle from beginning to end. Not only was it taxing on your streaming machine, it was also unintuitive and very few streaming softwares had native support for video playback. You either had to do funky screen/monitor capture, install third party plugins or both.
Nowadays playing a video in your broadcast is as easy as throwing up an image or a webcam. It's easy, fast, reliable and can up your production quality a great deal.
I prefer working with video since I have so much more control, variety and the options are almost limitless versus working with other popular methods such as CSS or HTML. Although these methods are fantastic in their own right and has other advantages that a video might not have.
