Your iPhone camera is amazing. Especially for video. Modern iPhones capture 4K video, and pretty much any iPhone from the past few years can easily do high-definition 1080p. It’s also likely that your videos will be stabilized, so they look smooth, like they were shot with a Steadicam, not a shaky human hand.
The sound, though, isn’t as good as the image. The iPhone’s microphones are good, but not nearly as high-end as its camera. Also, the best place for a microphone often isn’t right next to the lens. It’s better to put it as close to the sound source — usually a person speaking — as possible. The good news is that it’s easy to get much better sound on your iPhone videos. Here’s how.
