Well, there's a lot to say here. First, you should work on consistent stroke, regardless of grip (French, German, Swiss/Basel, hybrid, etc). Slow the stroke and focus on quality of sound and maintaining a vertical stroke, even and marcato (same speed up and down). Then work on staccato (faster down than up) and legato (faster up than down). Eights (8 eighth notes per hand) is fine for doing this. Be less concerned with how it looks than how it sounds.
Second, he's done an admirable job of gaining speed with (and I don't mean to sound judgmental here) pretty unrefined technique. Learn to use your fingers, wrist and arm to create motion. Think of these as a range: closer to the stick is finesse, farther from the stick is power. Practice rudiments from slow to fast to slow, pianissimo to fortissimo to pianissimo, open to closed to open. What you'll notice is that fingers are more responsible for pianissimo, arm for fortissimo; fingers for fast, arm for slow; fingers for open, arm for closed.
There is a great Sonny Emory video on YouTube where he shows a great exercise where you maintain your fulcrum but you finger exercise each finger through sets of eights. I'll look for the video and add the link.

Once you improve fingers, wrists and arms, the next big leap is combining these into the Moeller motion. There are several good videos on YouTube about this, but it is the most natural means of playing fast, musically.
