Submissions will be edited. Please let the camera roll 10 seconds before and after the action. Use off-camera microphones, if possible, especially for interviews. If it is necessary to use the on-camera mic, try to do the interview in a quiet environment and keep the camera close to the subject. Monitor the audio.
Some cameras have manual controls for audio input, while others do it automatically.
Minimize distortion and eliminate distracting noise if someone is talking. If the camera has an earphone jack, it is helpful to listen through headphones during the recording. Don't be shy. Get close to the subject. Ask for permission ahead of time to approach platforms or podiums.
