With filming a music video, comes a responsibility. Organisation is key, making sure all your dates are marked down, and the actors know when the filming is being done. Also exaggerate your time, if you think it will take two hours of your time, say it might take two and half or three hours, then they can work their day around that time.
Make sure you have all the equipment you need: Camera(s), Tripod(s), lights, set and actors. Be sure to double check everything you need is working and take an extra battery or a charger in case your camera dies.
Have everything planned out, have your storyboard on hand, even if you stray from it slightly, keep it for your structure. Film the scenes in order, it will make editing much easier.
Make sure your actors know what they're doing. Give them the lyrics/script in advance so they can learn the words. Let them know if they need to do anything that they might never have done before (dancing, acting). Make sure they know where they are supposed to be on the day of filming, and what they are going to be wearing (hair, makeup ect...) this will take the pressure off you if they already know what they are doing.
Make sure you have booked anything to you need, for example for my music video I wanted a plain white background that was large enough for me to walk around in, so we could get full body shots. In order for us to do that we had to search local places that will let us use a space like that. My filming partner, Rachael rang up different studio to enquire about using their space. We managed to book a studio in Barlow, just outside our local town.
Being organised and making sure things like this are booked in advance is vital, especially if you have a deadline.
