VideoClip.pixelAspectRatioDenominator

Description

Returns the denominator of the pixel aspect ratio (numerator:denominator). (Read Only).

The pixel aspect ratio (for example, 10:11) determines the shape of each pixel. The first number (10) is the numerator and is the width of the pixel. The second number (11) is the denominator and is the height of the pixel. You can use the pixel aspect ratio to resize a video to appear less stretched.

// This script creates a plane, adds a VideoPlayer component and plays a video on it. 
// It uses the pixel aspect ratio denominator and numerator to resize the plane to prevent the video appearing stretched.
