My advice

by FilmmakerGuy

I started my first documentary a year ago last October. I've shot one feature narrative and am currently working on the documentary, and both formats require a different set of philosophies. With a narrative, you almost have to have a well-planned, well-organized shoot. But with a documentary, you just have to do the best you can under the situation you're in. That said, rule number one is:
1) Get the shot. Try to arm yourself with the best camera you can afford, the best microphone, the best crew, and if you're setting up an interview, try to make the room as welcoming as possible

Popular Q&A

Are wireless microphone transmitters universal?

Or do they have to be specific brands/models to go with certain receivers? I have a Sennheiser EM1, and a handheld, and I'd like to buy a wireless lavalier and transmitter to use with it as well. It used to come packaged with the Sennheiser SK2 transmitter, but it is both discontinued and not sold seperately.

My question is, can I buy any old transmitter and assign them both to the same channel? Or does it have to be the new Sennheiser G3 transmitter that costs $250?

Thank you!

The receiver and transmitter have to be on the same frequency and not necessarily brand specific, Be careful of the type you get, The frequency band for wireless mics has changed and the top end has been lopped off. Make sure you don't get one that only works in the bit that is now illegal and has been "dumped" by someone else.
