Introduction

In the world of video production, character generators (CGs) play a vital role in creating visually appealing graphics to enhance storytelling. Whether it's displaying on-screen information or generating elaborate motion graphics, CGs have become a critical staple in the live broadcast environment. In this article, we will explore the basics of character generators, their features and functionality, how they work with software and hardware, and the role of CG operators in the live broadcast environment.

What are Character Generators?

Character generators, often abbreviated as CGs, are artistic informational tools used in video productions to generate characters and graphics in real-time. CGs originally referred to the generation of characters, but their usage has evolved to include elaborate motion graphics as well. The term CG is often interchangeable between character generators and computer graphics, as they both involve the combination of software and hardware to create visually appealing content.

Why Do We Use Character Generators in Video Productions?

Character generators are used in video productions to enhance storytelling and provide visual information to the audience. Whether it's actively displaying character names or passively sharing stock market data, CGs help engage viewers and convey important information effectively. With real-time graphics, CGs allow for dynamic content creation during live broadcasts, making them an essential tool in the video production industry.

The Basics of Character Generators

Character generators have a primary function of generating characters and graphics to be displayed over live video. This involves the use of software and hardware components to create and output visuals in real-time. Manufacturers offer different software choices, typically requiring a computer system with a standard operating system. The hardware chosen is essential for high-performance graphics processing, with high-end CGs opting for the latest graphics and video output cards.

Features and Functionality of Character Generators

Character generators vary in their user interface, features, stability, support, and cost. CG software allows for the design and creation of graphics, with options for customizing the graphics' appearance. Some CGs even offer customized keyboards to enhance the user experience. One standout feature is the ability to connect to and display external data, such as Excel files, RSS feeds, and scoreboards. This enables real-time data integration, expanding the possibilities for on-screen information.

How Character Generators Work: Software and Hardware Interaction

The interaction between software and hardware is crucial for character generators to create desired graphics. The software allows users to design graphics according to the video resolution they will be outputted to. Once the graphic design is complete, it is sent to the frame buffer portion of the output video card through the software. The output card then generates the graphic into an actual frame of video, which is sent to the receiving device through various mediums, such as composite, HDMI, or SDI.

Character generators can be used in two ways: internal keying and external keying. Internal keying involves the system internally keying the graphic over the video source and outputting the final composite as a single video source. External keying provides two independent video signals from the output card, one for the graphics or fill information and one for the graphics alpha or key information. These signals are supplied to a switcher to perform the composite of the graphic into the live video signal.

The Role of CG Operators in Live Broadcast Environment

CG operators play a significant role in the live broadcast environment. They are responsible for managing and recalling graphics on demand as directed by the show director. CG operators maintain active communication with the director, who may have specific graphics in mind or rely on the CG operator's expertise in graphic selection. This collaboration ensures smooth integration of graphics into the live broadcast and enhances storytelling through visual elements.

Communication Between CG Operators and Directors

CG operators and directors maintain open communication during live broadcasts. Directors may call for specific graphics to be displayed, and CG operators may suggest relevant graphics to enhance the story. CG operators can also cue and execute graphics based on the director's instructions. This communication ensures that the graphics are seamlessly integrated into the broadcast and align with the director's vision.

Cueing and Executing Graphics

Cueing and executing graphics involves precise timing and coordination between the CG operator and the director. Graphics can be outputted to the frame buffer for the director to review before transitioning them on-air. In some cases, graphics have blind reveals, starting off invisible and then animating into view. The CG operator works closely with the technical director to execute the graphics' transitions and compositing, ensuring a smooth and visually captivating broadcast.

Conclusion

Character generators have become indispensable tools in the live broadcast environment, allowing for real-time generation of visually appealing graphics. From generating characters to creating elaborate motion graphics, CGs aid in storytelling and providing valuable information to viewers. CG operators play a crucial role in managing and executing graphics during live broadcasts, working alongside directors to enhance the overall production. As technology advances, character generators continue to evolve, pushing the boundaries of real-time graphics integration and engagement.
