The International Award Association will be entitled to edit the video as they feel appropriate. The content of your film may be used in future productions. Keep the camera as steady as possible even when you may be filming handheld shots. Wherever possible, place the camera on a stable surface, eg. a table if a tripod isn't available. This will also allow you to guarantee a better, more consistent focus.
Most camcorders have automatic features which compensate for differing lighting levels.
As with photographic cameras, keep the sun or any bright light sources behind the camera in order to best light the subject and to avoid lens glare. The sound must be on the video tape. Most on-camera microphones are good but do stay reasonably close to the camera in order that the microphone can record your voice clearly. Too much distance between you and the microphone will produce disappointing audio results with hiss, bizz and possibly ambient background noise also. So stay close to ensure good, clear sound recording.
