Take Advantage of Image Magnification Screens.
One way to avoid the expense of hiring a crew to record video footage is to tap into image magnification screens. If you perform live at an event and there are more than 500 attendees, there is usually a large screen image magnification system so the people in the back of the room can see you. The image magnification is accomplished by hooking up a video camera to a projector. IMAG systems appear in many performance situations, including rock concerts, conventions and conferences, sporting events and illusionist performances, to name a few. If these systems are present, many times there are video recorders in the system, too. Ask the producer if you can have a gratis copy of your performance, or negotiate it into your fee.
Keep some blank tape up your sleeve.
It’s a good idea to carry an external hard drive with you when you speak or perform, just in case the venue you perform at doesn’t have any spare hard drives. It would be a bummer to have a killer opportunity to be video recorded in front of a great audience and the only thing stopping you is the lack of something as simple as video storage.
