Calculate video aspect ratio dimensions from width or height. Convert 16:9, 4:3, 2.35:1 cinema, and vertical 9:16 for social media and broadcast formats.
Calculate video bitrate from resolution, frame rate, and quality target. Estimate file size and streaming bandwidth for H.264, H.265, and ProRes workflows.
Estimate video storage needs from bitrate, duration, and clip count. Plan SSD, NAS, and cloud storage for editing archives and raw footage libraries.
3840×2160 = 8,294,400 pixels = 8.3 MP per frame.
Pixels = Width × Height; Megapixels = Pixels ÷ 1,000,0004K UHD is exactly 4× the pixels of 1080p — double linear resolution each axis.
Scale Factor = (W×H) target ÷ (1920×1080)4K at same quality needs ~4× bitrate of 1080p for inter-frame codecs.
Bitrate scales roughly with pixel count × frame rateUpdated: July 2026
1920×1080 = 2.07 MP. 3840×2160 = 8.29 MP. 4K is 4× pixels — impacts storage, GPU, and export time.
DCI: 4096×2160 (8.8 MP). UHD: 3840×2160 (8.3 MP). Different width for cinema vs consumer 4K.
19.9 MP per frame. Oversampling for 4K delivery crop or reframing in post.
Compare video resolution specifications and calculate total pixel count for production planning. Enter width and height or select preset (720p, 1080p, 4K UHD, DCI 4K) to get megapixels, aspect ratio, and relative scale vs HD.
