Do you have a video that you want to share with your friends or family over the internet, but the video is too large that you can’t send it? Do you have to record your homework and upload it to the learning platform so that your teacher can check it? So here is a question how to make video smaller to make all the processes easier and quicker? If you are bothered that you can’t transmit the large video successfully, read this passage. We have several ways to recommend to solve these issues.

You can directly jump to the part you need, or you can read the passage along to understand the reasons make video size large and the ways to address the problems.

Part1 Factors Affecting Video File Size

There are three factors affecting the video file sizes, including resolution, bitrates & FPS, and encoding. Next, we will talk about these three factors respectively and discuss how to make a video smaller to email or other ways to others.


Display resolution is the number of pixels displayed on the screen, such as 1920*1080 (number of horizontal pixels × number of vertical pixels), the higher the resolution, the more the number of pixels, the finer the image. In the same size of the screen, the higher the resolution, the better the display effect. But relatively, because the more information is recorded, the larger the file will be. Therefore, if you want to compress your video size, you can just change the resolution of the video.

Bitrates& FPS

Bitrate refers to the number of bits per second (bps) transmitted. The unit is bps (Bit Per Second), the higher the bit rate, the larger the data transmitted. Bitrate means how many bits per second are needed to represent the audio and video data after encoding (compression), and bit is the smallest unit in binary, either 0 or 1. The relationship between bit rate and audio and video compression is simply that the higher the bit rate, the better the quality of the audio and video, but the larger the encoded file; if the bit rate is less, the opposite is true. Bitrate refers to the sampling rate of digital sound and video from analog format to digital format, the higher the sampling rate, the better the restored sound quality and picture quality.

Frame rate is also called FPS (Frames Per Second) for short – frames per second. It is the number of frames per second that the image is refreshed, and can also be interpreted as how many times per second the graphics processor can refresh. The higher the frame rate the smoother and more realistic animation can be obtained. The more frames per second (FPS), the smoother the displayed action will be.


Encoding is the process of converting data into a format required for a number of information processing needs, including:

  • Program compiling and execution
  • Data transmission, storage, and compression/decompression
  • Application data processing, such as file conversion

Encoding can have two meanings:

In computer technology, encoding is the process of applying a specific code, such as letters, symbols, and numbers, to data for conversion into an equivalent cipher. In electronics, encoding refers to analog to digital conversion.

Part2 Methods to Make Video Smaller Size

Reduce Resolution

As we can see the higher the resolution, the larger the file will be. If you want to make video smaller size, you can reduce the resolution of the video. That is one of the most effective ways to compress the file size. Generally speaking, HD videos are 1920 x 1080 pixels. If you want to share it with others, you can compress your video to 1280 x 720p or 854 x 480p. But if you compress the video, there will be some quality loss.
