Saving a Blender animation is the process of preserving the animated sequence as a file on your computer. This allows you to share your animation with others, continue working on it later, or use it in other projects.
There are several different ways to save a Blender animation, depending on the format you want to use and the purpose of the animation. The most common formats are AVI, MP4, and WebM, which are all video formats that can be played back on most devices. You can also save your animation as a series of images, which can be useful for creating GIFs or other types of web graphics.
