Video file format is a file format for storing
digital video data on a computer system. Video is almost always stored in compressed
form to reduce the file size.
A video file normally consists of a container format (e.g. Matroska) containing
video data in a video coding format (e.g. VP9) alongside audio data in an audio
coding format (e.g. Opus). The container format can also contain synchronization
information, subtitles, and metadata such as title etc.. A standardized (or in
some cases de facto standard) video file type such as .webm is a profile specified
by a restriction on which container format and which video and audio compression
formats are allowed.
Common video file extensions include AVI, MKV, MP4, MPG, MOV, WebM, WMV, and
so on.
 GIF
(Graphics Interchange Format) is a bitmap image format that was introduced by
CompuServe in 1987 and has since come into widespread usage on the World Wide
Web due to its wide support and portability.
The format supports up to 8 bits per pixel for each image, allowing a single
image to reference its own palette of up to 256 different colors chosen from the
24-bit RGB color space. It also supports animations and allows a separate palette
of up to 256 colors for each frame. These palette limitations make the GIF format
unsuitable for reproducing color photographs and other images with continuous
color, but it is well-suited for simpler images such as graphics or logos with
solid areas of color.
GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression
technique to reduce the file size without degrading the visual quality. This compression
technique was patented in 1985. Controversy over the licensing agreement between
the software patent holder, Unisys, and CompuServe in 1994 spurred the development
of the Portable Network Graphics (PNG) standard. All the relevant patents have
now expired.
- GIFs are suitable for sharp-edged line art (such as logos) with a limited
number of colors. This takes advantage of the format's lossless compression, which
favors flat areas of uniform color with well defined edges.
- GIFs can be used to store low-color sprite data for games.
- GIFs can be used for small animations and low-resolution film clips.
- Since a single GIF image palette is limited to 256 colors, it is not usually
used as a format for digital photography. Digital photographers use image file
formats capable of reproducing a greater range of colors, such as TIFF, RAW or
JPEG.
