Removing fan noise in footage using FCP

I have audio that has a low-freq fan hum. I have a long time ago read about a built-in (?) filter in FCP that analyzes the hum, and using phase-turn eliminates (or at makes it less noticeable).
But I can't find that filter? I tried the Hum remover, but to me that filter is more for removing that 50 (or 60) Hz humming you might get when using poor audio cables.
Any tips is greatly appreciated!

You will find that if you remove the fan noise completely, you'll also damage the voice. A blower generates a full spectrum sound. THe absolute best way to fix this is at the time of the recording

Removing Fan Noise

I shot a wedding in August and it was terribly hot in the church. They had setup many many fans to cool off the audience, which was nice but the audio for the ceremony has the underlying fan noise in it. The groom was mic'd and the only other source of sound I have is from the shotgun mic on the camera, eliminating the fan noise at the time of recording seemed impossible with the equipment that I had.
I am able to do the reduce noise and you can barely hear the fan noise but it makes the audio sound like it is in a tin can, is there anything I can do to not make it sound so tinny? I have tried to remove the noise to the point where the tinny sound starts but you can still hear the noise very loudly, almost making the noise removal pointless.
Any suggestions?
Thanks
Jeff

If the noise is a very low hum (low as in frequency, not amplitude), try using the low cut filter under process . . . eq and filters.

Removing Fan noise from lighting

First, thank you for your responses... Secondly, I know these problems should be thought of in advance and not to rely on post so I would appreciate help rather than criticism...
There is noise from the fans of the lights. A single person is speaking to camera in an inside room. I have reduced noise (set noise print –> reduce noise) in ST Pro, which got rid of fan noise (-45db), but distorts the voice so it sounds like he is speaking underwater. I added an EQ filter, but can't get this to sound very good...
I have Soundbooth CS5 and FCS. Thanks for any help.

STP noise reduction has a tendency to do that rather quickly. The only thing that helps is to reduce the amount of noise reduction which defeats much of the purpose.
First first adding some parametric eq to reduce the bad frequencies and then do a noise print and noise reduction, using less reduction, no lower than about 54dB.
You can also go into the spectrum analyzer and try to carve out the bad frequencies. This is more difficult than in Soundbooth's version, which is were I generally head off to for that sort of work.
Recently I've been trying Isotrope's RX noise reduction and find it miles ahead. Where I was using it I found I had to back up and reduce background in a lot more shots I'd previously just skipped over. It's one of those things that can be too good. It's spectrum analyzer is also quite good.
Good luck

What is causing the very Loud Fan noise everytime I use the computer? What is causing the Heat as well? Please help

Please Help!
My computer has been making very LOUD fan noises. I know this cant be normal. How can I fix this issue?
This has been going on for a while now. As soon as I turn on the computer....the noise starts.

Go check out Activity Monitor on your Mac. It will show you which programs are running, and how heavy their use of your CPU is.
When mine does this, for some reason, I have a bunch of "Managed Clients" running at once. I use Act. Mon. to shut them down, and my Mac runs normally.

Removing Wind Noise from Audio in FCP

Is there a way to remove/filter wind noise from audio for use in FCP?

I'm not sure if you're if your sarcasm is targeted at me or Apple but just to clarify:
By rolling off the bottom end prior to using a Noise Print style NR technique you'll get a far better end result than just asking something like SoundSoap to decipher everything.
Wind noise is dynamic. NR tools like SoundSoap and other basic noise tools do not adequately address it. Since much of the problem with wind is in the very low frequency range simply rolling that stuff off cleans up the signal significantly and sometimes is all you need. Adding noise print style NR after the LF has been eliminated will produce a much better result.
Another technique for changing the perceived amount of interference from a dynamic source like wind is to copy a chunk of relatively clean ambient tone and pasting it over areas where there is noise but no dialogue. This step will obviously not help of a strong wind gust happens over the voice but it does improve the overall perceived quality of the recording. I usually don't offer this suggestion right off the bat because it's more of a surgical procedure which takes a bit of skill. What most people are looking to do is just clicking on the "remove noise" button.

HT3964 How do I stop my Macbook from overheating and making a fan noise?

My Macbook Pro 17 Inch keeps overheating and making a fan noise after I use it for... say... an hour.
I use Windows on my Macbook, is this related to my problem? If not, do I need to get my fan replaced?
It gets annoying whenever I play a game, and then suddenly my Mac goes to sleep for no reason (probably due to overheating).
The fan noise is kept to a minimal when I use a web browser, or listen to music, but it goes up when I start an application.

Since overheating is something the computer tries to prevent, it will shut down if the temps get too hot, thus your experience is not overheating.
You can have a look at Activity Monitor (Menu Bar > View > Show All Processes) and then sort by CPU to see what the culprit is during downloading.
A hot Mac is not that big of a problem, the fan takes care of the heat and if you do not mind the noise, then that is it.

IMac G5 fan noise

Hi MGW,
Baby Boomer recommended that I check with you about our iMac G5 fan noise since you used to have the same model. For a reference as to what all has been suggested and done go to: http://discussions.apple.com/thread.jspa?messageID=9810894&#9810894
I've done some internet searches and come across some other ideas on what may be the problem and if it is not too much trouble I would be very interested in your thoughts about the suggestions by DeathStalker13 --- please scroll down to #19 at this link:

Here is another link that I've found information about iMac G5 fan noise. I'd also like your impression about the methods that these people have done to solve the issue:
http://scienceman.com/legacypgs/00imacG5fanforum.html
I've also contacted a local AASP store and from just our telephone conversation they think just cleaning the fans and inspecting the computer which would take 1-1/2 hours at $95/hour should take care of the problem.
We'd really appreciate you opinion. Thanks!!!

Thank you so much for answering so quickly. I apologize for not being able to do the same. We had unexpected house guests and everything else was set aside while they were here.
This morning I have been researching trying to figure out how to disable Flash but so far I've been unsuccessful. We have a Power PC Mac OS X 10.4.11, Safari version 3.2.1.
Under the Safari "Help" it says, "Safari works with the plug-ins that are installed with Mac OS X. To see a list of installed plug-ins, open Safari and choose Help > Installed Plug-ins."
I checked and the Installed Plug-Ins list only has one "FLASH" listed - Shockwave Flash. I didn't know how to disable it or if I should.
You suggested changing to Firefox or Camino. We already swap between Safari & Firefox (version 3.0.12) for other reasons. Unfortunately, the fan noise is the same whether we use Firefox or Safari.
It was interesting that under Firefox "Help" they recommended disabling Adobe Flash plugin: http://support.mozilla.com/en-US/kb/Usingthe+Flash+Plugin+withFirefox?style_mode=inproduct
They said something about, "vulnerable to an extremely malicious exploit" and that until Adobe has an update, you can disable Flash. I followed the instructions but the only plug-ins I found were the following:
Default Plug-In
Netscape Navigator Default Plug-In
Java Embedding Plugin 0.9.6.4
Runs Java applets using the latest installed version of Java. For more information: Java Embedding Plugin. Run version test: Java information.
Java Plug-in
Java 1.3.1 Plug-in
Java Plug-In (CFM)
Java 1.3.1 Plug-in (CFM)
QuickTime Plug-in 7.6.2
The QuickTime Plugin allows you to view a wide variety of multimedia content in web pages. For more information, visit the QuickTime web site.
Shockwave Flash
Shockwave Flash 9.0 r159
Shockwave for Director
Macromedia Shockwave for Director Netscape plug-in, version 10.1.1
I haven't changed anything yet, as I'm not sure what I should disable. We have considered putting up with the fan noise since it isn't as bad since we cleaned the fans but if there is an easy fix we'd really appreciate your advice. Thanks!

Suggestions for removing video noise from converted Hi8 footage

I am about to start capturing Hi8 material into FCP 6 through a Sony D8 camcorder that does the analog to digital conversion. Even after cleaning the tape heads, I notice a very few lines of noise at the very bottom of the frames - like a dirty head. From the camcorder side everything looks normal - no noise. From the FCP side in VTR mode you can see the noise. I am not sure if this is an artifact from the analog to digital transfer or if the tape head is still dirty.
Question: assuming I cannot eliminate the noise on transfer/input, is there an easy way to apply a universal filter or horizontal "clip" function to imported video to remove the bottom few lines of video? I guess I could always overlay a black canvas covering only a few lines on the bottom, but maybe there is a more elegant solution?
Thanks in advance for any counsel!

What you are seeing are timing errors that are an artifact of analog recording and generally are outside the viewable area of a CRT TV (i.e. in the overscan zone). If you are setting these up for digital presentation - web or computer play only, these items may be seen.
You have a couple of options to deal with the tearing ..
• Recapture the material using a Hi8 deck and a separate analog/DV converter with a full frame Time Base Corrector between the tape machine and the analog/DV converter. This will clean up the timing errors but is an expensive proposition.
• Crop the image. This will leave a very slight letterbox effect and may not be noticeable unless you mix the material with non-cropped material.
• Slightly enlarge the material so that the tearing falls outside of the 720x480 area. Expanding images much beyond 110% softens/pixelates the images noticeably and my not be acceptable.
• Live with it.
Good luck.

Is it normal to get fan noise after 5 minutes of use?

Each time I use my Mc=b Air, fan noise starts within few minutes of use while office temperature remains cool.

It is not normal.
Fan
The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.

I am using XDcam footage in FCP

How to i import footage into FCP without losing image quality? how do I get footage into a DVD authoring program without losing image quality and what is best program to use? THANK YOU!!

There is no loss importing into FCP. There is always loss going to a disc based delivery system. DVD is only standard definition and heavily compressed. Blu-ray is much better, but it is far from lossless.

Increased fan noise, CPU temp and random fan rpm bursts when using Leopard

I have a 2.2 Ghz Macbook Pro that I purchased in August 2007. I was running OS X Tiger on my mac till about a week ago when I decided to upgrade to OS X Leopard. Ever since the install, I've been facing numerous problems and issues with the general functionality of the computer. Specifically, the biggest issue relates to increased fan noise and random bursts of increased fan rpm (as monitored using iStat). I did not have any of these issues when using OS X Tiger. Further upgrading to 10.5.1 wasn't helpful either as it did not resolve the issue.

Welcome to Apple Discussions!
It may be worth running the Apple Hardware Test, just in case you have a sensor going out or something like that. Sometimes and upgrade will cause an underlying problem to make itself known.
Did you do an Upgrade as opposed to an Archive and Install or an Erase and Install? If so, there could be some software problem associated with the issues you are having. I tried an Archive and Install, and had so many issues that I went ahead and did an Erase and Install. I've had no problems since.
Good luck!

Editing stereoscopic footage ("3D film") using FCP

Does anyone have any work around to doing stereoscopic editing using FCP?
We've been debating the viability of wrapping the left and right eye images in Quicktime, making it "invisible" to FCP.
I am curious if anyone has evaluated or used the product for stereoscopic film editing.
Markus

I only know that Avid has just announced support for stereoscopic editing in Media Composer v3.5. FCP has never claimed any real ability to do it that I know of. I always assumed that people edited with just one eye, then separately assembled the two images for screenings. If the timecode matches for both eyes that shouldn't be too hard. But if you need to edit and monitor in 3-D all the time I'd guess you're looking at some hard work to make it happen in FCP.

Fan noise after an hour of use

I was installing a package which took approx. an hour. At the end of the hour, I could hear the fan noise. That's the only time I have heard any noise (for that matter). Is that normal. I have a Mac Pro 15" Retina. Thanks!

This may help explain the fan's operation: Learn about the fans in your Mac
After installing a package Spotlight activity increases, and it's normal for that to cause temporarily elevated temperatures. The fans should quiet down in a few minutes.
If you suspect something abnormal read: Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity

Mac Pro 2x2,8 Ghz - Fan Noise - Please help evaluate

Hi Guys,
Since yesterday, I'm the proud owner of a Mac Pro 2x2,8 - Really happy - really nice machine.
However I'm slightly irritated by the posts I've read all over the internet, saying that you can't hear the fans of this machine at all in idle.
As you may have guessed, my box is not silent at all - it is quite quiet compared to other noisy PCs, yes, but no match for the previous iMac 24" which it replaced. You could hardly hear the iMac versus now the Mac Pro... you notice it's there... sitting under the desk - audible.
I realize that fan noise is highly subjective, and I'm using the Mac in a completely silent environment. No AC, no nothing. I've tried the following: removing the hard drive and silencing the graphics card... Upon bootup the Mac would quickly "turbo" it's fans and then go to it's normal state. The loudest fan (which is drowning out all other noise) is the one at the bottom front (CPU?).
Looking at istat, it's in normal parameters (500rpm or so) and doesn't move up or down...
Comparing it to other devices, it would sound like a PS3 when having played 1 hour (fan speed at level 2-3) or an (quiet) xbox in idle mode (dvd not spinning). I know... geeky comparisons
Now, again - not close to my interpretations of "whisper quiet" "can't hear it at all"... "only hear it when I put my ear to the grill" "sounds like it's cooled passively"
Which makes me think that either
a) people out there are deaf /
or
b) my Mac needs a closer look by a genius
Would really appreciate your opinions.
Thanks,
Tom

hey tom,
you might have the same problem i have. I have the 2.8 octo 2008 mac pro. and it used to be whisper quiet. I was amazed. But recently as in the last few weeks the graphics card fan has become audible. I put in an e sata adapter last week and while inside the mac pro I took a look at the fan to see if it was dusty or visibly distressed. Nope. Couldn't find anything wrong with it. So now i'm just dealing with the noise. Which is too bad cause I really really really don't like fan noise. But the air conditioners on most of the time now so I really can't complain about a little fan noise compared to the ac's grumbling.
but i'd like to know if others are having this problem
thanks,
