• A. Editing
• B. Switching
• C. Encoding
• D. Rendering

Answer: (B)

In video production, the process of selecting between multiple video sources and applying effects to the final output is called switching. This happens in real time with a video switcher, where you choose which input (camera, playback, graphics) is shown and you can add transitions, overlays, or on-air effects to the program feed as you go.

Editing, by contrast, is arranging and changing footage after filming for a finished project. Encoding is about compressing video for storage or transmission. Rendering is generating the final frames of a project, usually after applying effects in post-production. Switching is specifically the live action of choosing sources and shaping the live output.
