Would it work that sound wave produced by the K3 would be digitally deleted? And then have clear sound?

Thank you.

If you are refering to the feature on Final Cut Studio's Soundtrack that will sample a sound and notch it out of an audio track, it can work amazingly well but keep in mind that it does remove those frequencies from the audio and might make the remaining audio a little thin. Also, you should record a clear few seconds of the sound alone IN THE ENVIRONMENT you are filming with the same mic placement for it to work properly.

Federico, what you are referring to is digital noise reduction.


For it to work you need the following.

1. Sound of the Camera Running w/o any dialog/speaking (from the same MIC position).
2. Sound Recording of the Dialog and Camera Running.


With the two you can "scrub" the sound out.

It helps to record in 24bit/48khz or better and to use one of the following programs.

P.S. Using too much of this noise reduction creates "ring-modulation" synthesizer artifacts.
Combined with a 4-band EQ you can get it down to a minimum, but not remove it all-together.

ADR (Automatic Dialog Replacement should help.)


Here are some products that perform this function.

1. Adobe Audition (Used to be Cool Edit ) - Noise Reduction Menu (Pretty Decent)
2. Apple Sound Track Pro / Logic Pro - Audio Units Plug-in.
3. Digidesign/AVID Protools DINR (Inteligent Noise Reduction RTAS plug-in)
4. BIAS Inc, Sound Soap 2 and Sound Soap PRO (Audio Units and VST)
5. Sony Pictures SoundForge/Vegas Noise Reduction plug-in VST and DXi.

Also you may need a decent Audio Units, RTAS/TDM or VST 4 band EQ.

Sony GML EQ seems to be the most precise to RTAS/TDM and Audio Units.
Pushtec EQ or Waves EQ is good if using Native/VST or other Windows Stuff without Protools.

Non-withstanding your room ambiance will be removed along with the camera noise.
But you can fake it with Convolution and Impulse Reverb Plug-ins.

Hope it helps.



Best is to wrap the camera in carpet/jacket/blimp and hold the MIC far away.

What worries me is the sync. If the camera is only used with the spring-wound motor there will be trouble syncing, right? If shot with the Tobin motor (or other) it may keep in sync. How can this be solved since there are lots of old Bolexes and K-3 around. It would be great to invest in 16 mm on a budget. Thanks! By the way, vivo en México DF
