Are you addicted to recording videos? If the answer is yes, you must have encountered some circumstances that you need to shrink video file size, for example:

The video file size is too large for uploading to YouTube, Facebook or the like. You need to shrink the video size smaller, so you can share it on the web.
You’re willing to send a video to your friends by email. But you know, email has no access for large size videos so that you must compress video for email to make it accessible.
You want to put a camcorder recorded video to small-screen mobile display, while the video resolution is too large to be played on mobiles. Thus it’s wise choice to downsacle the video resolution to fit the mobile’s screen and compress it for smaller size.
You have a collection of videos, which took up a lot of storage space on your device or hard drive. In order to store more videos, you can shrink video size to free more storage space.

What Are the Factors Affecting Video File Size?

How can you shrink video on Mac and Windows for smaller size? Average users may be aware of seeking a video shrinker and know how to twitch some of qualities to reduce a file size like resolution and such dimly. But that’s not enough. To reduce video files size smaller but better quality, you should know what matters for video size indeed.

1. Codec

A codec is a software tool used to compress or decompress a video. Different codec uses different compression algorithm to encode video files. And the codecs used to compress the video will determine the ratio of quality to file size. For example, the HEVC improves up to 50% compression efficiency over H.264/AVC, while AV1 is claimed to boost 30% coding efficiency compared with HEVC and VP9, but same high quality. And owing to codecs are wrapped in various fomat containers, we have a test to convert a same video (H.264 codec MP4 of 1.05MB) to different codecs and formats as bellow:

Codec	H264 (original)	hevc	DivX	MPEG4	WMV2
Container	MP4	MP4	AVI	MP4	WMV
Size	1.05MB	486KB	3.01MB	2.99MB	2.75MB
Quality	Good	Excellent	Excellent	Good	Good

2. Resolution

The resolution describes the number of horizontal lines your video has in each frame and it’s displayed in width by height. Take 1920x1080 as an example, it means that there are 1080 horizontal lines, each 1920 pixels wide. The smaller the resolution is, the smaller your video size will be. But there are some common display resolutions for digital devices, like 1920x1080, 1280x720, 960x640 etc. You are not recommended to downscale resolution too much of your devices’ display screen, or else you’ll get poor video quality.

3. Frame Rate (FPS)

The frequency at which separate frames are displayed. It’s expressed in frames per second. The higher frame rate your video has, the larger size it will be, but more fluent at the same time. The main standards for video frames go for 23.98, 24, 25, 29.97, 30, 50, 59.94 and 60.

4. Bitrate

Bitrate, aka data rate controls the visual quality of the video and its file size. Higher quality files have a higher bitrate. If your bitrate video compression software gives you the option to choose variable bit rate, select 2-5 Mbps for SD, 5-10 Mbps for 720p, 10-20 Mbps for 1080p, and 30-60 Mbps for 4K videos to get the best visual quality.

5. Duration

It has been a common sense that the video file size grows with the duration. If your video is too long and too large, you can trim the length of video to divide it into pieces. If you’re trying to upload video to YouTube , Facebook that have a strict limit for video length, you might as well try this method after you’ve done other settings.
