when taking videos of a solo piece ...... I mean no compas or background rhythm, that noise in the background which sounds like wind is killing me I really hate it it sounds like f..sh..sh..sh..sh..sh..sh..sh..sh
does anyone know anything about this case ? how to deal with it ? or reduce it ? I even tried with cams with cost of 300$ and still got the same sound
I played with some plug-ins from vegas like " Track Noise Gate "or" Neat Video " they're 50 % efficient I guess ...
anyway thought some of u might use some tricks or know some info and would like to share
Sounds like AGC is kicking in (Automatic Gain Control). A lot of cheaper video cameras have it on all the time - see if you can disable it and go manual for your levels.
Wind is tough to solve in post-production (depending on how bad it is), even if you have to ability to control levels at a sub-frame resolution you won't be able to do much of anything about wind noise over instrument/voice. When mic-ing something on location a good wind-shield for the microphone is essential, unfortunately good ones aren't cheap (see rycote.com).
rolling off low frequency is a partial solution, of course it plays havoc with the target subject fidelity.
I don't use vegas but none of the stock filters I've tried in pro-tools or adobe apps work very well, sometimes they help a little on dialog.
Do you mean actual wind or the space in between louder noise? I thought you meant the hiss, when there is nothing going on - which is almost certainly AGC.
sorry Escribano I wasn't so clear ... but actually I didn't mean the actual wind .. I mean the sound that happen when the room is silent .. I don't know how to describe it .. but lets say for example I am in a silent room and I'm recording the scene without making any sound .. when revising what I recorder .. you will probably still hear something sounds like wind but it's not an actual wind . but the reason I called it like that .. because it was described on most sites on the internet as wind noise .
anyway I think I can't get rid of it ... I can only reduce it a little . and btw IZotope RX has some nice features
I know next to nothing about this--and would actually like to see someone confirm or reject this advice--but here's something I found on an Internet forum a year or two ago.
One person said:
Take any eq, and dial in a single band with a narrow q. Then boost the band to the max and sweep it across the entire spectrum until the noise pops out. Then, just cut that frequency and adjust q to taste. It works even better if you loop a small 'room tone' section that just contains the offending noise and not a bunch of other stuff.
Another person added: To elaborate a little further on what he said, use a peak (not shelf) EQ set to a narrow Q (bandwidth), set it to a high level of boost and sweep its frequency across the spectrum until the noise is most exaggerated. Be careful with monitor levels as you do this, as the offending frequency could get quite loud.
Once you've found the frequency, fine tune it by narrowing the Q even further and sweeping the frequency in minimum steps until the noise is most accurately spotted. Then, without changing the Q, fully attenuate the EQ band. If the noise disappears, try less cut until you hear it again, then back down again until it's gone, but no more. This way you the minimize side effects.
If it's still there after the initial attenuation setting, then try widening the Q until it's gone. If that doesn't quite fix it, or if there is too much unwanted effect on the overall sound, try adding in a second (or third, or fourth) band set to the same frequency to increase the attenuation. If it's available, Waves Q10 is an excellent EQ for this application, but most parametric style EQs (adjustable boost/cut, frequency, and bandwidth) will do a good job too.
Can you load an example? What Escribano wrote about AGC would cause exactly that... raise the gain in silent moments, causing a lot of shhhhh then lower as you play, with some delay.
Room acoustics would come last on my list, and doubt they would resolve hissing. Only after I had bought decent low noise ration recording equipment and removed all noise making devices from the room, including your computer would I start working on that, none of this is cheap.
Fixing a recording after the fact is like putting a band-aid on a cut you can always see the scar, better to remove the broken beer bottles from the floor... so work at a clean source... but the band-aid is probably a cheaper solution.
Everybody has cameras now, it's worth trying your friend's to compare.
I just listenned with cheap headphones (what I have here) and with those I can hear the hiss at the beginning and at the end, in silent parts, not sure, with these headphones, if it's still there when you acutally play.
I'm no expert by the way, just sharing this from my own experience. Escribano's ACG is still very possible, in my case it was a little easier, it was hissing constantly, old or crapy camera, I just stoped using it.
I think I see a window open at the back, I would normally want that closed. But what kind and model of camera is it? And I would definitely try some of my friend's camera to test them out.
Hey, I listen to it with proper speakers and the hiss is there throughout so I doubt it's anything like fluctuating gain. I think it's just a crappy mic of a regular camera, what I hear is hiss and not background noise.
If you have a mic, it's pretty easy to test record yourself with it in the same spot. Like I said I just stopped using my camera and used a good mic with a good sound card, all with high signal to noise ratio.
If you can fix at the source then you'll be stuck to do patch up work using eq or noise reduction.
now I have an idea of what is happening. @rogeliocan : I guess you're so right .. I need a new recording set, coz mine isn't that good . @Ron.M : you're exactly saying the truth .. because after a second thought this results is very good according to the room I was in. @at_leo_87 : thank you man I will grab that adobe right away.
make sure the section you capture for the noise profile has only noise and no guitar sounds. the keep noise button is useful too. i used to select it and raised the noise reduction until i heard just a tiny bit of guitar. then i unclicked it and selected remove noise.
that way, i didnt remove too much and just kept the good stuff.
adobe audition is really good. there's so much stuff you can do with it.
