Best Video Quality Setup for Reducing Video Size

Before we move to the free online video compressors to scale down your video file, let's briefly discuss the classic video qualities and technical aspects that define the physical size of your video file.

Classic Video Quality, Resolution and Aspect Ratio:

	Official Name	Pixel Size (width & height)	Aspect Ratio
8k or 4320p	8k video (Full Ultra HD)	7680 x 4320	16:9
4k or 2160p	4k video (Ultra HD)	3840 x 2160	1:1.9
1440p	QHD (Quad HD)	2560 x 1440	16:9
1080p (recommended)	Full HD	1920 x 1080	16:9
720p	HD (High Definition)	1280 x 720	16:9
480p	SD (Standard Definition)	852 x 480	16:9

To reduce the file size of 4k or 8k videos while still retaining their video quality, it's highly recommended to scale down the video resolution to 1920 x 1080p (Full HD) or 1280 x 720p (HD) because these two video qualities promise the best viewing experience online and compatible with the all online video hosting platforms.

So, in addition to the video resolution (like 4320p, 2160p or 1080p, 720p, or the number of pixels used to form a video image), what else defines the physical size of a video file? Well, there are 4 more elements:

Bitrate: Bitrate refers to the amount of digital information transferred into audio and video per second, or also known as bit/s. The higher the bitrate, the bigger the video size and better video quality. For example, a 1080p video has 8Mbps while a 720p video has 5Mbps.

Frame Rate (or FPS): A video actually consists of tons of images. And the frame rate determines how many images are shown consecutively per second. The higher the frame rate, the smoother the video and the bigger the file size. For example, most films and TV series are shot with 24 FPS.

Encoding and Encoder: Imagine that a video is a car and the video resolution, bitrate, frame rate, etc. would be different auto parts while the encoding and encoder should be the chassis and frame of the video. The commonly seen encodings are H.264, H.265 and the encoders are MP4, MOV, and AVI, etc.
