When I was using the DJI Mavic Pro drone in Cappadocia, Turkey, I forgot that I set the camera to capture images in 16:9, so I ended up with a bunch of wide images like the image you see above. The same goes for choosing extremely wide aspect ratios, where the camera crops the top and bottom of the frame, as in the image below: This image in was captured in 16:9 aspect ratioĬappadocia, Turkey. When aspect ratio is expressed in decimal numbers such as 1.50 or 1.50:1, it ignores the orientation of the image. For example, 3:2 indicates a horizontal image captured in landscape orientation, whereas 2:3 refers to a vertical image captured in portrait orientation. Lastly, when aspect ratio is expressed in two numbers separated by a colon, the first number typically refers to the horizontal side of the image, whereas the second number refers to the vertical side. When looking at image dimensions in pixels, a 6000×4000 image from a 24 MP camera also has the same 3:2 aspect ratio.
For example, the aspect ratio of 3:2 could translate to an image that is 3 meters wide and 2 meters high, as well as 3 feet wide and 2 feet high. It is important to note that aspect ratio does not represent the physical size of an image, or its dimensions in pixels – it refers only to the relationship of its width to its height. Nikon’s CMOS sensors have a 3:2 aspect ratioĪs discussed further down below, some cameras allow choosing different aspect ratios through the camera menu, providing cropping options other than the native one of the image sensor. All modern full-frame and APS-C DSLR cameras have 3:2 aspect ratio sensors, whereas 4:3 is a popular choice among smartphone, Micro Four Thirds and some medium format camera manufacturers. The most common aspect ratios of modern digital camera sensors are 3:2 and 4:3. The aspect ratio is often determined by the form factor of the camera’s film / imaging sensor, which is practically always rectangular. Similarly, an image with a 3:2 aspect ratio would be represented by 3 equal size units for its width vs 2 units for its height, as shown below: For example, a 4:3 aspect ratio would consist of 4 equal size units for its width and 3 equal size units for its height. You can easily visualize any aspect ratio by allocating units to the width and the height of an image. Some even prefer to express aspect ratio as a decimal, followed by a colon and number 1, such as 1.50:1. It can be expressed as a number followed by a colon and followed by another number, such as 3:2, or by a decimal number such as 1.50 (which is simply the long side divided by the short side).

PIXEL ASPECT RATIO CALCULATOR DOWNLOAD
You can download and read the documentation in the following links. MP4Box is a multiplatform command line tool that serves as a multimedia packager, with a vast number of functionalities: conversion, splitting, hinting, dumping and others. This calculator it's made in order to calculate a correct display aspect ratio for an anamorphic video, for example, you have a 720×480 DV video with an 1:1 storage aspect ratio and you want the video to be displayed as 16:9 display aspect ratio, in order to look correctly you need to use MP4Box to change the data/flag inside the video that handles the aspect ratio information to “32:27”, as you can see this is not “16:9” and that’s because MP4Box utilizes a very peculiar way to handle the aspect ratio information and it’s not the standard known aspect ratios that you’ll find on most DVDs boxes, it uses fractions to avoid non integer numbers (decimals or floating point values) so that’s the reason you have to manually calculate this values.
