## Description

Gifify is a tool for converting video files into optimized animated GIFs. It functions as a video to GIF converter and optimization utility that extracts specific clips from video files and burns text or subtitle overlays directly into the frames.

The project differentiates itself through specialized GIF optimization, using lossy compression, color count limiting, and custom color palette generation to reduce file sizes. It also provides precise control over the output by allowing users to adjust playback speed, reverse playback direction, and resize dimensions.

The software covers a broad set of video processing capabilities, including timestamp-based segment clipping and frame-by-frame image processing. These operations are handled via a command-line interface that supports stream-based media processing.
