What is an AVI file?
Audio Video Interleave (AVI) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows technology. It adheres to the Resource Interchange File Format (RIFF) specification, storing audio and video data in tagged chunks (specifically 'movi' lists) to allow synchronous playback. While widely compatible, the legacy AVI architecture lacks native support for modern features found in MP4 or MKV, such as variable frame rates (VFR), B-frames, and sophisticated chapter markers. It typically utilizes codecs like DivX, Xvid, or MJPEG.
How to open an AVI file
AVI files enjoy broad compatibility on Windows via Windows Media Player. However, because AVI is a container that can hold various codecs (e.g., DivX, Xvid), playback may fail if the specific codec is missing. macOS users can view AVI files using QuickTime Player if the content is MJPEG, but third-party players are often required for other codecs. VLC media player and MPC-HC are standard recommendations for handling the vast array of codecs potentially encapsulated within an AVI file.

What is a GIF file?
The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987, distinguished by its use of the Lempel-Ziv-Welch (LZW) lossless data compression algorithm. It supports up to 8 bits per pixel, allowing a palette of 256 distinct colors selected from the 24-bit RGB color space. The GIF89a specification, introduced in 1989, added support for transparent backgrounds, animation delays, and application extensions, establishing it as a standard for simple web animations and low-color graphics.
How to open a GIF file
GIF files possess near-universal compatibility and can be opened natively by all modern web browsers (Chrome, Firefox, Safari, Edge) and default operating system viewers like Microsoft Photos and Apple Preview. No third-party software is typically required for viewing. For editing frame-by-frame animations or modifying color palettes, raster graphics editors such as GIMP, Adobe Photoshop, or online tools like Ezgif are required.
