Measuring video involves assessing various aspects, from its technical specifications to its perceived quality and delivery performance. Technically, we look at factors like resolution (e.g., 1080p, 4K), frame rate (e.g., 30fps, 60fps), bitrate (Mbps), and the codec used (e.g., H.264, H.265). Beyond these, objective metrics like PSNR (Peak Signal-to-Noise Ratio), SSIM (Structural Similarity Index Measure), and VMAF (Video Multimethod Assessment Fusion) are crucial for quantifying visual quality that correlates with human perception. For streaming, key performance indicators include startup time, buffering ratio, and seek latency, which directly impact user experience. Ultimately, the goal is to balance visual fidelity with efficient delivery and storage, ensuring an optimal viewing experience across different devices and network conditions.
