I am assumming a VHS-C or Video 8 source, which isn’t all that great as a video source to begin with, but here’s some basic tips.
You could apply a slight colour curve and a touch of contrast (0.010 or 0.020) to reduce the washed out look and possibly add a slight sharpening.
The colour corrector is only necessary (in this case) so that your whites look white. If you just want to ‘boost’ your colours and give them a bit more ‘oomph’, take a look at Saturation adjust and boost your mid tones (it’s one of the presets).
Shooting outdoors in bright sunlight is always a challenge, and I would shoot with a camera using an ND filter to be able stop down the iris.
