![]() The most obvious place to find background footage for your chroma key is the Telestream Stock Media Library, which was introduced in Wirecast v12. If you don’t want to create your own backgrounds, there are several ways to obtain them online. Using the same camera for both your background movie and your broadcast is a good way to ensure the aspect ratio is consistent. Also keep in mind the aspect ratio that you will be streaming in. Fast motion can distract from your on-air talent. For movies, start with slow subtle moving backgrounds. However, you will be surprised at how easy it is to capture a great background image or movie. It will take a couple of tries to find what works and what does not. The best way to get started is to simply grab your camera and start shooting. 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. You might also find that several other people found the same background as you. You may spend a lot of time and money to find just the right background for your project. Please keep in mind that if you are broadcasting live you need to own the rights to the background images you are streaming.Īnother great way to get images or movies is to create your own. Most other image types will work, but those formats will give you the best quality. I would also suggest you bring in the highest quality images you can in PNG, TIFF, JPG, or BMP format. Otherwise the background may get distorted, squished or stretched. This is helpful because when you bring the image into Wirecast you want the resolution of the image to match the resolution of your stream. In the advanced search options, you can specify a specific resolution you’d like to search for. Type in any subject and you will find thousands of photos. I suggest you start with a Google Image search. Starting with a simple picture background is a fun and easy way to get started. Some of these background packages may also include “props” you can use in the foreground, such as a (fake) news desk. ![]() This makes the scene look even more believable because as you switch cameras the background changes. Each camera in your studio can be assigned to the background with a similar angle. Some background packages will even include multiple images or movies, each with different angles of the same scene. However, a movie of a beach with a slowly swaying palm tree or moving waves may create a more realistic scene. Your talent in front of a simple image of a beach may create the setting that you like. The types of backgrounds available from stock media libraries vary in complexity. The chroma backgrounds that you insert can be a movie or a picture. Broadcast from your new high quality news desk or live from the beach. They allow you to insert an image or video behind your talent, allowing them to virtually enter a set or location. The Chroma Key (Green Screen) functions in Wirecast are a great way to enhance your broadcast.
