[xmonad] Layout demo screen recorder recommendations sought

Hi folks, I've been working on a new layout, specifically for ultrawide displays. I'd like to record a demo of the layout in use. Does anyone have any recommendations for software for that, formats to publish in etc. etc. One caveat is that being for ultrawide monitors, the unscaled frame size would be pretty large (5120x1440 for mine) which might present some special issues ... advice would be most welcome.
