Mini Lesson

Every time you press the red record button on a phone or tablet, you are doing something that would have seemed like magic just 100 years ago — capturing real life in sound and pictures that you can play back any time you like. Devices today have incredible tools built right in that let you record, create, and share your world.

What is audio recording?

  • Audio recording means capturing sound — voice, music, nature sounds, stories — as a digital file.
  • The device component that picks up sound is the microphone.
  • Common uses: voice memos, podcasts, audio stories, narration for a project, recording a song.
  • Tip: speak clearly and hold the device 6–12 inches from your mouth; avoid covering the microphone with your hand.

What is video recording?

  • Video recording captures both moving images and sound at the same time.
  • The camera lens captures the image; the microphone captures the sound — both work together.
  • Most tablets and phones have a front-facing camera (for selfies and video calls) and a back camera (for filming outward).

How to frame a good shot

  • Landscape orientation — hold the device sideways (horizontal) for wider scenes, most videos, and nature shots.
  • Portrait orientation — hold the device upright (vertical) for close-ups of a person’s face or a tall object.
  • Keep your subject centered or slightly off-center — the main thing you are filming should be clear and easy to see.
  • Check the background — make sure nothing distracting is behind your subject.
  • Hold the device with two hands and brace your elbows — a shaky camera makes it hard to watch the recording.

Playback

  • After recording, press the play button to listen to or watch what you captured.
  • If the recording is too quiet, move closer to the microphone next time or increase the device volume.
  • If you are not happy with the result, record it again — practice makes perfect!

Safe recording rule — always ask first

  • You must always ask permission before recording another person — even a friend or family member.
  • Recording someone without their knowledge or consent is disrespectful and can be harmful.
  • Never share a recording of another person online without their permission and a trusted adult’s approval.

Ask yourself: "What does a microphone do? What does it mean to frame a shot? What must you always do before recording another person?"
