Calculate the storage needed for your DVR or calculate the amount of footage time your DVR will hold. This easy to use tool calculates the estimated video storage needed based on different codecs, qualities, resolutions, frames per second, motion percentage, quantity of cameras, and the amount of time to hold onto data measured in days. You can also calculate the amount of time in days or even years a system will archive before the oldest data is overwritten. Currently uses the following codecs: -H.264 -H.265 (full version only) -MPEG4 -MJPEG Currently uses the following resolutions: -352x240 (1CIF) -704x240 (2CIF) -704x480 (4CIF) -1280x720 (720p) -1280x1024 (1.3MP) -1600x1200 (2MP) -1920x1080 (1080p) -2048x1536 (3MP) -2288x1712 (4MP) -2560x1920 (5MP) -3840x2160 (UHD) Measures data in kilobytes, megabytes, gigabytes, terabytes, or petabytes to the nearest 1/100th.

How many pixels in a 12 megapixels image? How does that compare to difference aspect ratio? What is the resolution of Digital Cinema with 21:9 aspect ratio? How many megapixels by giving X width and Y height by image? How about the aspect ratio? The answer is here! This is a megapixel-resolution calculator, a tool to calculate and convert the graphical resolution base on 4 different aspect ratios 4:3 (SD), 16:9 (HD/fHD/4K), 21:9 (cinema) and 1:1. This tool also calculates and convert graphical resolution to megapixels. The output will include 4 different aspect ratios 4:3 (SD), 16:9 (HD/fHD/4K), 21:9 (cinema) and 1:1 if the ratio match one of these. Preview box will give you an impression for resolution input. 21:9, 16:9 and 4:3 is the ratio of x:y or width:height of the image sensor or output image/video format. Older digital cameras/camcorders aspect ratio is usually 4:3 (SD). However newer digital cameras/camcorders aspect ratio is 16:9 (HD/fHD/4K). Video cameras such as camcorders can be either 4:3 (SD) or 16:9 (HD/fHD/4K). Some camcorders (video and digital) can do both 4:3 (SD) and 16:9 (HD/fHD/4K).
