Teknik Detay
Video rec. 2020 follows standard aspect ratios: 1920x1080 (1080p/FHD), 2560x1440 (1440p/QHD), 3840x2160 (4K/UHD). Bitrate requirements scale roughly with pixel count — 4K at equivalent quality needs ~4x the bitrate of 1080p. For web delivery, adaptive bitrate streaming (HLS/DASH) serves multiple quality levels based on network conditions. Most viewers watch on mobile screens where differences above 1080p are imperceptible, making 1080p the sweet spot for web video delivery.
