You can see if the drama studio or lecture theatre are free but keep it simple.
Do not over complicate the filming.
Get the right MES (costumes), film the performance in a variety of ways – get the performer to sing and film in close up – get the performer to sing again and this time film it in long shot – get the performer to sing again and this time film in mid shot – get the performer to sing again and use some movement/angles. Then change MES and locations if you want.
Use 2 cameras at any one shoot so that you can double up during performances.
You will then have several different sequences to cut between. SIMPLES!
PROPS – use upturned bins for drums……blow up guitars……electronic keyboards for pianos. IT IS ALL ABOUT THE FILMING!
You only have 1 lesson to get your performer dressed, rehearsed and filmed. You need to be organised.
Sometimes LESS IS MORE!
