First of all, the footage is too bright. Blackpoint seems to be at 30~32 RGB, which is too high. Depending on the RGB<>YUV conversion standard, this is either 16 points too high ("Studio RGB"), or 32 points too high (sRGB).
With levels corrected, you'll find the footage has more overall contrast, and less need for sharpening. (Perhaps it could be sharpened a 'lil bit, but then, it would be beneficial if the already-present "edge-enhancement" (dark halos beneath bright features) would be removed prior to that.)
