I've never performed on TV, but if I were I would follow the advise of Gary Ouellet. In short:
(I assume your doing close-up in an uncontrolled environment i.e. at the mercy of the producer and director.)
- Choose something simple DO NOT try something new.
- Avoid threads and such.
- Avoid angle problem effects.
- Prepare for things that could go wrong and work on the "outs".
- Try to get a "front only" camera shot.
- Avoid any kind of backlighting.
- Do the trick for the Director and tip him/her to the secret, so they work with you.
- Do not show the trick to the host, you want a real reaction.
- Play to the camera "home audience", completely ignore the live audience.
- Talk to the camera, which is two feet away.
- Choose short effects.
- Choose visual effects, (color changes for example.)
- Forget about the magi at the club, your audience doesn't even know about the club.
- Do magic in the hands close to your face, if possible.
- Plan on only one take.
- And last, but not at all the least: SELL YOUR PERSONALITY and not the trick. Do a trick you and everyone else really enjoys.
Audition your audience ahead of time, walk around performing card tricks while the director is getting ready, and watch for people who react to your magic- these people will be placed near you before the red light goes on. Also, add lots of comedy, it greatly helps you be likeable.
If you really want to be on television you can do it. Never give up. It can can make your career blast off. Just ask Michael Ammar (hopefully he answers), The Amazing Johnathan, Lance Burton, Alain Choquette, David Copperfield, Brett Daniels, Bill Malone, Luis De Matos', Melinda, The Pendragons, Mark Wilson, and a host of others.
