One 4k screen could show 4 1080p videos at once. I guess it is preference but keyboard and mouse if definitely the way to go I think. The goal of input devices is to minimize the amount of time and effort it takes to translate what is in your head to what is on the screen. Keyboard/mouse/controller literally only require flicking your fingers to see what you want. Custom keyboard shortcuts could be created for fast-forward and rewind. That plus alt+tab and/or multiple 4k monitors and you're probably flying through videos faster than hand waving.
