Abstract

Kinemaster is a very complete professional video editor application that can edit multiple layers of video, images and text, complete with precise video cropping. When the user performs video editing activities, and saves the edited video file, it will produce a video file that has a high resolution. Because the higher the resolution and duration of a video, the greater the video file size. Therefore the file size will cause problems because it is limited by storage capacity. To solve this problem, a solution is obtained by compression. The Prefix Codes algorithm is a lossless compression technique, which does not remove previous information, where the decompression of the compressed video is the same as the original video file. By using the Prefix Codes algorithm, the performance is a Ratio of Compression of 2 bits, a Compression Ratio of 50% and a Space Savings of 50%. These results prove that the compression of the extra video files by Kinemaster by applying the Prefix Codes algorithm can reduce the size of large video files to be smaller than the previous size.
