Record your monitor or a window then upload to Youtube, Gfycat, Twitter, or Facebook. You can also save to file. You can upload to Gfycat anonymously (without an account). For Gfycat, anything longer then 15 seconds needs to be converted to a GIF. This is the rules of Gfycat's website. When saving to file, you can can save it in the default format, which is .WEBM, or you can convert it to a .GIF or .MP4. This is done thanks to the ff-mpeg.js library (27mb). This library is responsible for the large size of this addon. Some services, like Twitter does not accept webm uploads, so I use this lib to convert to MP4 or GIF before upload. All uploads use the resumable APIs, so you can upload large videos without worry of upload failure. If connection is lost during an upload, the upload will resume after the connection is available again. This uses WebRTC to record. If you have it disabled, it will be enabled for the recording and then disabled again.

Gone are the days when having moving images on your website meant having to use GIFs or Adobe Flash. The emergence of HTML 5 and its multimedia features has allowed designers to do without Adobe Flash or heavy, slow-loading GIF animations and, instead, use the native HTML5 video player. However, HTML5 only supports a few video formats, namely OGG, WebM and MP4.
