When filming live music, you must plan the shoot very carefully beforehand. We had three locked off positions and four camera operators. Planning the positions is vital - as is making sure you have battery power and recording time throughout the 90 minutes of the gig. It was vital we had a master that we could use at any time because the four main cameras were DSLR. As they have a maximum record time of 12 minutes, we had to stagger our recording to ensure coverage.
