Part 1: What Determines the Size of Video File?

Bitrate Decides Video Files Size

What is Bitrate?

Bitrate means the amount of video (or audio) data per unit time, and the unit is bps (bit per second), generally kbps (kilobits per second), Or Mbps (million bits per second).

Why bitrate decide the video size?

Different bit rates determine the degree to which the encoder compresses the video and are the key factors that determine the final video quality and file size.

The lower the bit rate, the higher the compression and the worse the video frame quality. The higher the bit rate, the higher the video quality, and the larger the video file size.

How To Understand It?

Use a simple way to understand it: for the same 1-minute video, the size of a 512kbps file (no matter what coding format or container format) is about 3.8MB, and a 1Mbps video, the size is about 7.6MB.

How to check your video bitrate on PC?

Read this article, you will learn how to check video bitrate: Find Video's Bitrate

After read this article, we will know:
1. The bitrate is proportional to the quality, but the file size is also proportional to the bitrate.
2. If the bitrate exceeds a certain value, it has little effect on the video quality.

Other Video Parameter is also Related to the Size of Video

The word "video format" is simple to be explained. Real video format contains two different meanings. The first is "video container format", and the second is "video coding format".

The most important point which could affect video quality is video coding format, whatever video container foramt is, 2 different video will have same quality if they have the same bitrate and same coding format.

In 2021, HEVC(h.265) is the best quality video coding format.

Resolution is a parameter used to measure the amount of data in a video frame, usually expressed as ppi (Pixel per inch).

For example, 320*180 video resolution, refers to the effective pixels in the horizontal and vertical directions. The ppi value(effective pixels) of the window is higher when the window is smaller, and the video looks more clear; when the window is enlarged, because there are not enough effective pixels to fill the window, the effective pixel ppi value drops and the video is blurred. (When zooming in, the distance between the effective pixels is enlarged, and the graphics card will fill these gaps, that is, interpolation. The pixels used in the interpolation are "false pixels" that are "guessed" based on the effective pixels' up, down, left, and right, and there is no original video information).

If two videos have the same bitrate, once you set one of them to a higher video resolution, this video quality will be lower than another.
If you want two videos to have the same video quality, once you set one of them to a higher video resolution, this video will have a higher bitrate, which also means a larger video file size.

FFrame rate(FPS): The number of pictures displayed per second. It affects the smoothness of the picture and is directly proportional to the smoothness of the picture. Frame rate larger, the picture will be smoother; Frame rate lower, the picture will be more jumpy.

If the frame rate is lower than 24 frames, the video we see will be stuck and very inconsistent. If the frame rate is higher than 24 frames, it is difficult for our human eyes to distinguish. However, if the frame rate is super high, it means more frames you watch per second, the video at this time will appear smooth and delicate.

Once you set a video with a great frame rate, the video will be smoother, and the video's bitrate will be higher.

tips

How to choose the most suitable video parameter

1. Select HEVC (h.265) as encoding format.

2. Select appropriate video resolution (suitable for playback equipment).

3. Select right frame rate(FPS): 30~60 FPS.

4. Select appropriate video bitrate.

Recommend Video Bitrate
Video size Resolution Bitrate
480p 720*480 1800kbps
720p 1280*720 3500kbps
1080p 1920*1080 8500kbps

Part 2: We Always Meet Video File Size Problem

problem01

Why can't my video be uploaded to social platforms?

Sometimes when you upload a video to YouTube/Facebook, the upload will be failed, one of the reasons is that the video size you upload doesn't suit their requirements.

The following is some SNS video upload requirements:

problem02

I have too many videos I want to store.

Sometimes you have CCTV(commercial or home) or dashcam, you will have plenty of videos be produced from CCTV everyday, at this time, you want to compress them or keep some parts of these videos.

And you always have many videos or DVD files need to storage on disk, but your disk doesn't have much space to store any more files, you want to make the video files smaller.

Also, many people have some blue-ray DVDs, they want to save them in a digital format to their PC or Mac.

problem03

I want to share funny videos to my best friend.

When you shoot an amazon video, you want to share it with your friends, but when you use Whatsapp/skype/email to send it to your friends, it says the file is too large, or the video upload speed is too slow.

Method 2 - Set Phone Camera Parameter

You can change the video parameter when you use a mobile phone shot video to reduce the video file size, keep in mind that the higher the resolution and frame rate is, the more space the finished video will take up on your iPhone. The following forms show the relationship between video parameter and video files size:

  • 720p HD at 30fps: 40MB per minute
  • 1080p HD at 30fps (default resolution): 60MB per minute
  • 1080p HD at 60fps (smoother video): 90MB per minute
  • 4K at 24fps: 135MB per minute
  • 4K at 30fps: 170MB per minute
  • 4K at 60fps: 400MB per minute

Part 4: More Tips About Video

low quality

How to improve video quality?

If you record a video in 720p, can it be upconverted to 4k resolution?

No, you can't, check the reason: "you can not convert 720p video to 4k"

Any other ways to enhance video quality?

Now, we have AI techology to enhance any video quality.
This AI-based video quality enhancer uses the deep-learning-based super-resolution technology and can enhance video from 480p (SD) to 1080p (Full HD), and from 1080p to 4K. A deep learning AI engine can study and analyze a low-resolution video frame by frame and create and fill in identical neighboring pixels to enlarge the frame by 300%.

lossless compress

What is lossless video file compression?

Lossless compression doesn’t throw any information out — instead, it simply stores the information in a more efficient way.

This type of compression enables you to perfectly reconstruct the original file. For example, you could compress a video file to make it small enough to send to another person. The recipient could then uncompress the file and open it on their computer without losing any quality.

In short, you’ll want to use lossless when you want a perfect copy of your video. It will take up more space, but the data will be preserved perfectly. If a “good enough” copy will suffice, lossy compression will save you a significant amount of space.

vr&ar

How about VR & AR?

In the future, it’s likely we’ll experience VR/AR in ways we can’t yet imagine. But, for now, there are plenty of imminent tech advances to look forward to. We’ll have faster, lighter, more affordable VR technology. And advances in smartphone technology (such as better cameras and processors) will mean we can enjoy slicker AR and VR experiences on our phones. And with 5G wireless networks, we'll be able to enjoy them wherever we are in the world.

8k

Is 8K the future video resolution trend?

We predict that 8K—an upgrade and complement to 4K resolution—will generate US$3.3 billion in global revenue in 2021, with this amount rising steadily over subsequent years. These revenues will come predominantly from sales of 8K TV sets to consumers (an anticipated 1 million units with an average selling price of US$3,300), with the standard becoming increasingly popular for the largest television set sizes. In addition, sales of equipment (such as cameras, monitors, storage, and computers) related to the creation and production of 8K content should generate hundreds of millions of dollars globally for the year.
