Yep, GIF sucks, but it's unfortunately the only thing even remotely close to video that's embeddable on most StackExchange sites and a whole lot of chat platforms. Ffcast also integrates selection of the capture area, which is a rather finicky argument to pass from xrectsel to ffmpeg. No need for it if you're capturing fullscreen.
