Method 1: Change the compression of file format. The premise of this method is that we need to install a decompression application, which will not affect the quality and clarity of the video and is easy to operate. However, there is no way to watch the compressed video directly, and it can only be used after decompression, and its compression rate is not high, which is not much smaller than that of uncompressed video. We can find the video directly in the folder. Right-click it and a menu will appear. Click the ".zip" button to add to XX.

Method 2: Compression without changing the file format. This method needs tools, and we can use computer fast video editing software to complete the operation. After it compresses the video, the video quality will be affected to some extent, but we can set the compression rate according to our own needs, either by percentage or directly by the compressed video size. The higher the compression ratio (the larger the amount of compressed video), the smaller the impact on image quality.
