High Definition (HD) encompasses 720p (1280×720) and 1080p (1920×1080), providing good quality for most consumer applications. Ultra High Definition (UHD) includes 4K (3840×2160) and 8K (7680×4320), offering exceptional detail for professional production and large displays. Each resolution standard serves specific use cases and target audiences.
Mathematical Foundation and Calculation Methodology
Frame size calculation follows straightforward mathematical principles: Total Pixels = Width × Height. The aspect ratio (width/height) determines the visual proportions and compatibility with different display formats. File size calculation incorporates bit depth (bits per channel), color channels (RGB=3, RGBA=4), and compression factors. The formula for uncompressed frame size is: Frame Size (bytes) = (Width × Height × Bit Depth × Color Channels) ÷ 8. This mathematical approach provides accurate estimates for storage planning and bandwidth requirements.

Frame Size Impact Examples:

  • Storage: 4K video requires 4x more storage than 1080p at same bit depth
  • Bandwidth: Streaming 4K requires 25-50 Mbps vs 5-10 Mbps for 1080p
