Product reviews and executive demos reward predictable mirroring more than maximum bitrate. Your audience cares that the tap follows the cursor and that fonts are readable on a projector—not that you squeezed an extra megabit per second from a dying Wi-Fi link.
Live mirroring answers “what is happening right now?” Recording answers “can I prove what happened later?” The hardware path overlaps, but the intent, disk usage, and post-processing differ—mixing them up leads to giant MP4 files nobody watches, or missing repro clips when QA needed them.
People rightly ask where their screen pixels, audio, and files go when they mirror. The short answer for NearMirror: the session is between your computer and your phone over USB or local network—not through a cloud “view your screen” relay.
Mirroring always trades quality, latency, and CPU/network load. Small adjustments on both the desktop and the phone side often matter more than chasing the highest resolution slider.
