Convert AVI to GIF

.avi

AVI stands for Audio and Video Interleave. It has an extension written as .avi, and users use this same format to store audio and video on their PC, which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by keeping video and audio into a single file. The simple architecture of .avi format will enable it to run on various operating systems such as Windows, Mac, Linux, Unix. It is supported by multiple web players as well.

AVI format uses Resource Interchange File Format (RIFF) support, where the real data is stored into chunks, and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag, and it can decode the chunk containing metadata for the video. The second chunk gets identified by the movi tag, and it includes the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.

GIF, Graphics Interchange Format, is one of the most popular bitmap image formats on the World Wide Web, allowing you to share images. It also supports transparent views of various animations. Such files are used to develop web advertising with sequentially changing pictures and the graphics shell of video files. They use scan-line images with the depth parameters up to 256 colors of the RGB palette. The process of compressing files in GIF does not affect the quality in any way, as there is no loss because of the compression technique. Due to this, it is possible to convert to other formats while preserving the original image properties. Many applications open the extension to view and process images and video content installed on PCs and mobile devices regardless of OS.

The format was developed by Compuserve specialists, especially for its use in the web environment, which provided broad public access to data on such files. The extension uses the LZW algorithm to carry out a parallel process with the removal of segments containing insufficient information. This ensures the preservation of high-quality pictures. Thanks to the Lempel-Ziv-Welch algorithm, the format handles graphic files with repeating sections well, particularly images with a large number of single-color pixels horizontally. Interlaced data storage is also possible. Scan-line data is compressed to the smallest size. Reducing the number of colors required to create an image is provided by removing shades unnecessary to perform this process. The range of available GIF colors is from 2 (black and white) to 256 while reducing the number of colors leads to a decrease in the file size.
