GIF Animation

GIF Animation is a Animation using "multi-image" of Graphics Interchange Format (GIF). Also known as animated GIF.
=About=
Multi-image is a feature introduced in GIF87a that allows you to display multiple frames in sequence. With GIF89a, you can now specify the waiting time.
The use of GIF is decreasing due to the limitation of the number of colors and the past submarine patent problem (→ Graphics Interchange Format # patent problem and its details), but the main alternative standard, animated PNG (Animated Portable Network Graphics, APNG), is GIF animation, which is supported in many environments, is still widely used as of 2021 because the web browser is still in the process of supporting it and JPEG does not have the animation function itself.
=Pros and Cons=
Since it is basically an extension of an image file rather than a video file, its operation and support status are based on the image file, which has both advantages and disadvantages.
There are also advantages and disadvantages common to GIFs.
==Pros==
Convenience for both creators and viewers is the greatest advantage.
*1.It has been supported as standard in many web browsers for a long time, and no plug-in etc. is required.
*2.No video editing software or web programming required. All you need is a still image and a simple conversion tool.
*3.You can use the <img> tag and <a> tag similar to his normal GIF image for HTML description.
*4.The background can be transparent (a function common to GIFs).
==Cons==
Not suitable for large videos for a variety of reasons.
*1.Has no stream other than images. In particular, it does not have an audio stream.
*2.Only up to 256 colors (= 28) can be used. Therefore, it is difficult to express natural paintings.
*3.There is no inter-frame compression.
**3-2.The same frame can be reused. In addition, since the compression rate can be increased by using the transparency function to make a frame containing only a difference image, it is possible to indirectly approach frame compression.
*4.Not playable on many movie players.
*5.In Windows Vista and Windows 7, it is not displayed in the standard photo viewer.
=Alternative=
As an alternative to GIF animation
*1.Video file (MPEG-1 / -2 / -4 etc)
*2.Continuously display images with JavaScript etc.
*3.MNG or APNG (equivalent to GIF animation for PNG, but a separate standard)
*4.Adobe Flash
*5.WebP animation function
and so on.
