Paul Frigon Posted November 14, 2007 Share Posted November 14, 2007 (edited) Hello I received a rx5 yesterday, and there is this part I cant figure. Is this an accessory ? Ive seen it on the pictures in a manual but no explanations. Looks like its a tiny light bulb that goes right under the gate. What is it for ? printing sound on the film ?! Thanks for your help Edited November 14, 2007 by Paul Frigon Link to comment Share on other sites More sharing options...

Nick Mulder Posted November 14, 2007 Share Posted November 14, 2007 Its for sound yes but not optical sound no... - I dont know the exact process as I doubt I will ever have use for it (although one day I might read up on it for interests sake) but the bulb would flash a frame of film for registration later in the editing process. It might make a interesting talking point key-ring or similar or there might be some Luddite film-maker out there who would really appreciate it (but probably has 7 of them already) - i.e. dont just throw it away !

Paul Frigon Posted November 14, 2007 Author Share Posted November 14, 2007 So its for sync, interesting. Thanks for the answers Link to comment Share on other sites More sharing options...
Premium Member John Sprung Posted November 14, 2007 Premium Member Share Posted November 14, 2007 So its for sync, interesting. Yes, it's called a bloop light. The way it works is that it's wired to a box that the sound guy has. That box outputs a tone and turns on the light when a button is pushed. The tone goes on the tape, so nobody hears it but the sound person. The light simultaneously fogs a few frames of film. This serves the same purpose as clapping sticks on a slate, but does it unobtrusively. It was used primarily for documentary work. The name "bloop" comes from what the tone sounded like when you rocked it back and forth in a synchronizer. Definitely either keep it or put it up for sale. -- J.S.

chuck colburn Posted November 14, 2007 Share Posted November 14, 2007 I believe the sync pulse came from the MST motor which also generated the pilot tone to sync the sound recorder. http://www.bolexequipment.com/MSTMotor.htm Link to comment Share on other sites More sharing options...
