How does Scott Kivowitz improve in-camera audio when shooting outside?

Scott improves in‑camera audio outside by using a high‑quality on‑camera shotgun mic instead of the built‑in camera mic, specifically the RODE VideoMic NTG.

The mic:

1. Mounts on the camera with a shock mount to reduce handling noise
2. Uses a windscreen to cut wind noise
3. Has high‑pass filters to remove low rumbles
4. Offers a safety channel and gain knob so levels are clean and not clipping
