So we can use the "advanced" photo mode (with fov, camera movement speed, camera angle, etc. not just hiding the hud) to create videos from the replays. A dedicated Play/pause key would allow to prepare the "shot" (position camera, find the angle, etc.) then press play and record (with shadowplay or similar), press again to pause replay and prepare the next "take" and so on. Rewind/FF keys would be a plus. Right now you can do something similar for screenshots as the "j" and slow/fast time keys work while in photo mode.
