How to Compress Videos with Video Compressor – Converter Otherwise, the image will look either stretched or squashed on a standard 16:9 display.
Aspect Ratios– While downgrading the video resolution, compression codecs ensure that the aspect ratio is maintained. By decreasing this rate, you can minimize the file size by a significant amount. 
Data Rate – This means the amount of data your screen displays per second. In other words, you can downgrade the quality of a 4K video by four times without screen-tearing. Resolution – if you have a 4K video file that you want to display on a 1080p screen, you can lower the resolution of the video file without losing any noticeable quality, as a 4K frame has over 8M pixels, while an FHD or 1080p frame has only 2M. These algorithms mainly focus on changing the following properties of your videos: Once the compression is complete, the file format of the original video will change depending on the codec. Some modern codecs like H.264, H.265, and VP9 are designed to balance the level of compression but not lose quality. This process is performed by using various algorithms called video codecs. If you’re using an outdated video compression tool, it may create blocky and distorted video clips. When you use video compression software, it will analyze all the pixels in a video frame and group the similar ones together in a larger block to compress them. It is done by removing repetitive and redundant elements, such as pixels, sounds, scenes, etc., from the original video. On a basic level, video compression means encoding the video file to take less space than the original file. What Is Video Compression, and How Does It Work?
