Television Production Process: From Capture to Emission
Production Process
Compilation of Information
The technical selection of capturing and recording each story is based on the concept of “informativa.” Facts are captured by cameras, and microphones record audio on tape or broadcast live. When recorded on tape using a VCR, the footage undergoes editing, processing, and post-production.
Camcorders, which are portable cameras with built-in recorders, allow for greater agility. The recording process has transitioned from analog to digital, eliminating noise and enhancing signal quality. Digital recording eliminates VCR signal degeneration and facilitates expressive editing.
Information services have their own production systems, separate from other programs. These systems include studios, booths, and mobile units. Cameras are typically mounted on tripods. There’s a growing trend toward improving technical quality and image and sound recording by replacing camera tubes with solid-state CCD sensors. The industry is also transitioning to the 16:9 format for cameras.
Computerization is crucial for drafting, documentation, assembly, and computer-based imaging. The news team decides which stories to feature, including those received beforehand, those on the agenda, and those that emerge during program preparation. A draft agenda remains flexible until broadcast time to accommodate breaking news.
Reporters cover news events, and the production team incorporates their reports into the program script. A final script is prepared before broadcast.
Production in Education
Newscasts often combine studio and on-location segments. One studio is used for news presentation, while another is used for recording interviews and program segments like the weather.
The studio comprises the set, control rooms, and sound and image control booths. This is where the visual presentation of the information is crafted.
Sound Control
Sound control monitors the quality of various audio sources, including studio microphones, speaker overlaps, and recorded music.
Image Control
Image control monitors the quality of images from the studio, video recorders, telecine, external feeds, and lighting.
Production Control
Production control directs and coordinates the work of the production crew before and during the program. They communicate with the presenter through headphones and microphones. During a live program, they monitor and select images and sound, and manage the arrangement and assembly of live visuals.
Studios mix various visual source inputs and use computer systems with specialized software for development. They are equipped with chroma-key technology, computers, and video walls.
Production Outdoors
Outdoor productions prioritize lightweight equipment for speed, mobility, and smaller crews, except for complex events. Journalists work closely with camera operators, utilizing available technical resources.
ENG (Electronic News Gathering)
ENG involves using a camcorder with an operational range of over two hours. It is operated by the reporter or a specialist. ENG is valuable for outdoor news, interviews, and short reports.
EFP (Electronic Field Production)
EFP utilizes lightweight mobile units with three autonomous cameras, a video recorder, editing equipment, sound equipment, and other resources for producing news and programs of moderate complexity. These units can handle on-site assembly and are housed in vans. They have microwave transmission capabilities for sending signals to the production center, and they can also use satellite channels.
Large Mobile Units
Large mobile units have five or more cameras and are used for covering complex events and live broadcasts. They use microwave links to send signals to a station, which then relays the signal to the broadcasting center. Signals can be encrypted to prevent unauthorized access to the footage. Mobile links can also be established from helicopters or motorcycles. The growth of digital satellite channels has made news transmission easier.
Post-Production Process
Editing and Production Equipment
The industry has transitioned to electronic editing. The integration of information allows for faster and more accurate technical setup. Recorders are connected to an editing console for electronic assembly. Two types of editing are common:
- Offline Editing: Allows for marking edit points using time codes.
- Online Editing: Uses the marked points from offline editing and employs professional equipment for a nearly automated process. This stage also includes adding titles, effects, and other post-production elements.
Technological advancements have provided real-time expressive resources for information, simplifying the production process. Computers facilitate the creation of headlines, animations, virtual reality elements, and graphics. Digital tape recorders can manipulate images to enhance or distort reporting, and they allow for making copies with minimal quality loss because they work from the original source.
Computers generate realistic images, icons, graphics, and diagrams, and they provide special inputs. Digital video recorders have multiple audio tracks for enhancing ambient sound, voiceovers, and music, improving the overall quality of the information presented. Dual-channel systems allow for an original language track and a translated track, while multi-channel systems accommodate multiple language versions. These audio capabilities are compatible with stereo and surround sound.
Hybrid systems that combine the functions of compact recorders and hard drives represent an intermediary step in the transition to fully digital workflows. Digital technology can be used with any camera; footage can be scanned, digitized, and treated with special effects. The output can be distributed across various media, including video, CD, and hard disk.
Reality, Computer Graphics, and Virtual Treatments
The use of virtual scenarios, pre-recorded image processing, and computer-generated imagery raises questions about the scope and limitations of information processing. It introduces the potential for manipulating information. Some television programs have incorporated virtual spaces to dramatize real events, blurring the lines between the virtual and the real.
Realistic animations are sometimes used in television to illustrate movements and actions. Computer graphics have enhanced realism and movement, creating the effect of lifelike motion. The merging of fiction and reality has led to new genres like docudramas and reality shows, as well as new forms of expression through simulations of events that may or may not have occurred.
