If you are editing videos, you’ll want something that helps you do it quickly and accurately. A real jog/shuttle wheel helps. Especially when it’s built into your keyboard. Of course whatever video editing software you are using has on screen interfaces that do the same things, but you still have to use a mouse and cursor to control them.
The GR100 keyboard adds just such a shuttle wheel so that you can turn to move quickly through a clip, and has an inner dial to locate the exact frame you are searching for. Some buttons around the dial allow shortcuts to other editing functions.
