The lesson
Good audio starts at recording: get the microphone close, choose a quiet room and record a few seconds of silence for noise reduction later.
A clap at the start creates a sharp spike in both camera and recorder audio; line up the spikes to sync.
Most editors can sync automatically by matching waveforms.
Step by step
- Record a short interview with a clap.
- Import camera and recorder files.
- Sync by waveform or clap.
- Check lip sync.
