The chroma backgrounds that you insert can be a movie or a picture. Wirecast does not include any backgrounds but it’s easy to import your own. I receive a lot of questions about where to get backgrounds. There are several possibilities to consider. Many websites sell or create images or movies that are specifically made for chroma backgrounds. Tube Tape is a great example.
The types of backgrounds available vary in complexity. Your talent in front of a simple image of a beach may create the setting that you like. However, a movie of a beach with a slowly swaying palm tree or moving waves may create a more realistic scene. Some background packages will even include multiple images or movies, each with different angles of the same scene. Each camera in your studio can be assigned to the background with a similar angle. This makes the scene look even more believable because as you switch cameras the background changes. Some of these background packages may also include “props” you can use in the foreground, such as a (fake) news desk.
Another great way to get images or movies is to create your own. You may spend a lot of time and money to find just the right background for your project. You might also find that several other people found the same background as you. Shooting your own backgrounds can be fun, effective, may save you time, and allows you to create a background that is wholly yours and unique. The best way to get started is to simply grab your camera and start shooting. It will take a couple of tries to find what works and what does not. However, you will be surprised at how easy it is to capture a great background image or movie. For movies, start with slow subtle moving backgrounds. Fast motion can distract from your on-air talent. Also keep in mind the aspect ratio that you will be streaming in. Using the same camera for both your background movie and your broadcast is a good way to ensure the aspect ratio is consistent.
Virtual-Studio-Set is another great site for backgrounds. They update with new backgrounds often. Several of their sets include moving parts, for example in the news room a large LCD screen drops down from the ceiling. With Wirecast, you can insert a movie into the screen that drops down. It is a powerful transition. Additionally, Virtual-Studio-Set has a free HD background for download every month. They are always good quality and great for experimenting with in Wirecast.
A search on the web may help you find other vendors. If you would like something custom-made, you can find that as well. Some vendors will even build a real set in a studio and take pictures so you have a virtual set. It all depends on what you want to do.
