- Online meeting between small groups of two or more people, OR a large audience
- Involves two-way communication (all parties interact), OR one to many forms of communication (viewers do not interact with presenter)
- Invitation-only events closed off to the public, OR open to anyone with the link
- Interactive features such as polls, surveys, and live chat
- Expensive and sophisticated equipment may be used, but not required
A webcast in its simplest form, only requires the following:
- Internet connection
- microphone (preferably not the built-in kind)
- streaming software
CameraIf possible, you should avoid using a computer’s built in webcam. Instead, use an external webcam, especially if this is going to be a low budget webcast with no live audience present with the speaker. Another factor for determining what type of camera to use is whether your webcast will stream live or on demand. If the streaming service has HD or 4K capability, the camera needs to have that capability as well. If the camera doesn’t have HD or 4K capability, then you’ll need a video converter with the ability to convert to HD. For “talking head” style webcasts, where one or more speakers will be close to the camera for headshots, external webcams and even high-end smartphones with HD cameras can do the trick. For any webcast involving multiple angles, live audiences, or in situations where there will be a lot of movement, a traditional camcorder is the best option. Webcams are beneficial when the webcast includes a single speaker sitting or standing in a static position, close to the camera, rather than in rapidly changing situations. This is where a camcorder with controls for everything from zoom, focus, to white-balance come in handy.
LightingWhen discussing what cameras to use in a webcast, you cannot ignore lighting. Avoid open windows or any sort of bright light behind the presenter. Bright lights in the background darken the face of the speaker or any object that is the focus of the shoot. Another thing to avoid is the mixing of lights of different “color” temperatures. For example, mixing indoor lighting such as fluorescent lights with natural outdoor light from a window, and mixing fluorescent with incandescent lighting can cause white-balance issues. In other words, the resulting image may have a colorcast with a washed-out appearance. Another smart practice in regards to lighting, especially when there is a single subject, is to use the three-point lighting technique. As mentioned previously, avoid using lights or any other distraction in the background. As the name suggests, three-point lighting consists of three lights: key light, fill light, and the backlight. The key light is the main and brightest light, and is usually set up at a 45-degree angle facing the main subject. The fill light cleans up any remaining shadows; therefore it is placed at a 45-degree angle at the opposite end of the key light. If there are any remaining shadows, a backlight, also placed at a 45-degree angle from the subject, is positioned right behind the speaker or main subject (Bolkan).
SoundGood quality video means nothing if the audio quality is poor. Many viewers find webcasts with poor audio to be a turn off, even if the video quality is excellent. Similar to built in cameras built in microphones do not produce the best results. It’s a good idea to invest in a separate microphone when investing in a webcam. Admittedly, a microphone built into a webcam is better than one built in to a computer, but often a camera may be positioned too far away from the speaker, which can lead to unwanted outside noise being picked up.
A Few Other Best Practices
- Knowing how and when to use visual aids. If the webcast is a voiceover, it is best to keep visual changes occurring at two to three second intervals. This way viewers do not lose interest.
- Good communication skills and practice. Having a presenter with good communication skills keeps the audience engaged. Even the best communicators need to practice to produce a professional result.
- If the webcast will be used for training where the script is too long to memorize, investing in a teleprompter may also be a good idea.
- On the day of the shoot, make sure to check everything more than once.
