Various factors can affect the size of a video file, such as resolution, aspect ratio, frame rate, color depth, and sampling rate. They are unique elements of a video but are often used interchangeably. Before resizing a video, you should understand how they would influence the video. Let’s have a quick look below:

• Video Dimension: the width and height of videos are measured in pixels and are collectively termed the “dimensions” of the video. For example, if a video is 1280 pixels wide and 720 pixels in height, it is said to have dimensions of 1280x720 pixels (also known as 720P).

• Aspect Ratio: the proportional relationship between the width of a video image and its height. For instance, a 4K video with a dimension of 3840x2160p has an aspect ratio of 16:9. It’s advisable to resize the video to 4:5 framed for Instagram or 9:16 for Facebook stories, TikTok, and YouTube shorts.

• Orientation: a video can be landscape, portrait, and square.
Landscape orientation – the longer sides of the rectangle are at the top and the bottom
Portrait orientation – the longer sides of the rectangle are vertical
Square orientation – the video is framed with a 1:1 aspect ratio

• File Size: technically, file size is expressed in bytes, kilobytes (KB), megabytes (MB), or gigabytes (GB) and determined by bitrate, resolution, frame rate, and encoding method. Resizing a video not only means changing the video dimension and aspect ratio, but also involves reducing the video size. Refer to the step-by-step guide to compress a video from GB to MB >>
