If you watch 1080p video on full screen, then yes, you can't move the slider exactly where you want it to be, because you can only jump to keyframes and slider has more empty between those keyframes because video is short.That video has total 7 keyframes (frames: 0, 5, 101, 105, 106, 108, 204, 300) so those frames are only points were you can navigate directly.
