Re: BMPCC - Microphone Prototype
It's quite a nice video, but I didn't see the microphone anywhere in it. :-P

Re: BMPCC - Microphone Prototype
Interesting!
Just a thought: if the operator sneezes while recording .... it's going to be in stereo? :-) Andrew |

Re: BMPCC - Microphone Prototype
Hi Wolfgang,
I am a bit puzzled by your prototype pocket camera powered microphone as I did not think there was any power available from the BMPCC. However I am impressed with the amount of detail and the shades of colour in your shots. Were you using ProRes HQ or DNG and also what lens were you using? |

Re: BMPCC - Microphone Prototype
Thanks Wolfgang,
Interesting, I have tested the same lens but was very disappointed with its sharpness and I returned it to my supplier. At that stage I did not add any sharpening which I am now trying with other lenses. |

Re: BMPCC - Microphone Prototype
Hi and thanks again Wolfgang,
More contrast and a bit more definition with the Nikon, is it the 60mm Micro Nikkor? What should I think about the colour patterns? |

Re: BMPCC - Microphone Prototype
I don't quite understand this topic, is it because you are going to try to sell the mic setup and are keeping what it all is a secret for now?
Anyways the sound sounds amazing to me so if you will ever share what it is and how to set it up please tell me as I would like to see how much all the pieces cost and if it is practical to build one myself, whatever it is that is. |

Re: BMPCC - Microphone Prototype
Dylan,
I am guilty of taking this thread off topic but I have also wondered about its original purpose. In the absence of any other information it looks as though the headphone diaphragms are being used as microphones with their outputs being fed into the BMPCC mic input. This would explain the placement of the wind protection fur patches but not the power consumption. |
