Answer:In a short infomercial, several codes and conventions are typically used to make the message clear and persuasive:1. Visual Codes: These include images, colors, logos, and symbols that are visually appealing and convey the brand's identity or message. For example, using bright colors to catch attention or a logo to build brand recognition.2. Audio Codes: These are elements like background music, sound effects, or voiceovers that create a mood or emphasize key points. For instance, upbeat music might convey excitement, while a clear, authoritative voice can establish trust.3. Language Conventions: This involves the use of catchy slogans, persuasive language, and direct calls to action (like “Buy now!” or “Don’t miss out!”) to motivate viewers. Short, simple sentences and repetition are often used for clarity and memorability.4. Technical Codes: These refer to camera angles, lighting, editing, and other technical aspects that shape the presentation. For example, close-up shots to highlight the product’s features or quick cuts to keep the viewer engaged.parate thanksss
