While this isn't exactly the intended use of this mod... and there may be issues with this idea I'm not thinking of, theoretically it would be really useful for those with less powerful computers to be able to record their gameplay with the replay mod, then simply render it back out into a flawless, high resolution, high framerate video for further editing. However, in order to do this the HUD would have to be recorded and played back when enabled in spectator mode. Obviously audio etc can be recorded separately and synced with the video with very minor performance issues.
