The only file format that allow animations and can be uplaoded to wikis by default is *.gif.

There are lots of ways to create GIF animations. Image editors like GIMP and Photoshop (see this and this) allow creating animations.

You can also create an animation in another format, like AVI or MWV, and then convert it to GIF with convertors like mediaconvert.

You can also create a SVG animation, but it will require embedding it using verbatim.
