Feasible methods to change aspect ratio for video files

Feasible methods to change aspect ratio for video files

Last updated on April 25, 2017 by

Aspect ratio is generally known as the ratio between width and height of a picture and video. When trying to fit a video or picture to a screen there are a range of aspect ratio’s available; 4:3, 16:9, 1:1, 2:1 etc. Generally, standard TV quality adopts the aspect ratio of 4:3 and the latest widescreen TV quality takes the ratio of 16:9. The viewing experience may be not good if the ratio doesn’t fit your media player screen perfectly. For this, it’s recommended to change aspect ratio by using professional editing programs. Because of this, I’d like to share some effective solutions for Windows and Mac OS.

Professional editing applications on Windows
