Key Video Terms and Concepts

1. Resolution

High-Level Goal: Understand what resolution is and why it matters in video production.
Why It’s Important: Resolution determines the clarity and detail of your video, impacting how professional and polished your final product looks.

• Definition of Resolution:
  Resolution refers to the number of pixels displayed on a screen, typically represented as width x height (e.g., 1920x1080). The higher the resolution, the sharper and more detailed the image.

• Common Resolutions:

• SD (Standard Definition): 720x480 pixels – suitable for older TVs and smaller screens.
• HD (High Definition): 1280x720 pixels – a step up in clarity for modern displays.
• Full HD: 1920x1080 pixels – the standard for most videos today.

• 4K (Ultra HD): 3840x2160 pixels – offers exceptional detail for high-end productions.

• Example:
  Think of resolution like brushstrokes in a painting. More brushstrokes (pixels) create a more detailed and lifelike image.

7. Dynamic Range

High-Level Goal: Learn about dynamic range and its importance in capturing detail in both shadows and highlights.
Why It’s Important: Dynamic range affects the overall quality and realism of your video.

• Definition of Dynamic Range:
  Dynamic range is the difference between the darkest and brightest parts of an image. A higher dynamic range captures more detail in shadows and highlights.

• Example:
  Dynamic range is like the difference between shadows and highlights in a photograph. A high dynamic range ensures both are visible and detailed.
