• The noise reduction for source VHS

  I am trying to edit video clips captured from VHS tapes it took years.  I wonder what is the best practice, or a quick and easy way to video noise, especially undulating video tapes at the bottom of the screen.

  Thank you!

  For tracking error, considered the horizontal band of noise to keep it from the image, you might be better to Scale-UP the Clip a little (fixed effect > Motion > scale), and then use a bit of movement > Position to effectively 'crop' off the coast of this background material. Note, with the scale, you will be as effectively "crop" slightly to one side, or both.

  For the video noise, I often use video neat, but it takes a bit of work, more adds perceptible time Renders and exports.

  Good luck

• I can't find anything in the manual that explains how the instant noise print settings in the noise reduction effect.

  I am a Pr/Ae user, not an expert in hearing.  I face an excerpt of interview with excessive noise HVAC air movement. I watched the tutorials and read the manual, I see nothing about this setting - noise Print Snapshots. (in the noise reduction) What is the difference in the output of different numbers and why?

  I'm also surprised to see if I'm doing the same NR twice on a clip (done by chance) really works better, without much in the way of artifacts.

  I'm trying to reduce the number of variables I have try different combinations.

  Thank you.

  Regarding the size of snapshot FFT - well, it is not easy to explain without going in the works of the FFT, and is not exactly notions... the best explanation of what the differences are is probably this one:

  Techniques of the noise reduction for Adobe Audition CC

  What it does not say on this page, that's what we discovered collectively using NR - and is that the best way to apply it is indeed in the stadiums-, but with a different size of the FFT for each one and not too wide in a go. You will get inevitably less artifacts of higher values, but they do not so well on the lower frequencies, so to a certain extent, it must analyze your noise; with CVC, you won't need the lowest setting, unless there are a lot of very low frequency "rumble" in the sound, and it is fairly consistent.

• The noise reduction does not work in Lightroom CC

  I have Lightroom CC with the most recent version installed as of May 17, 2016.  For some reason, the noise reduction slider doesn't do anything on any image.  Even at 100%, I can tell zero difference in the image.  Y at - it a bug that happens here or I do something wrong?  I use the same camera and image settings I have for more than 2 years.  Nothing has changed that I know.  Any ideas?

  Hi jeffb,.

  I tried the same thing at my end and I can change the Luminance, detail, and contrast of the image. I use WIndows 10

  Please check the picture you're working on doesn't fail, you can also try resetting that default return Lightroom preferences.

  Press the shift + option keys immediately after you restart Lightroom and select Preferences reset in the dialog box.

  Kind regards

• The noise reduction works only on MAC Lightroom 5.4

  I knew that the noise reduction that I apply to my photos is visible in the area of software development. I'm going to the library he disappears and the same thing happen if I export the image in any format.

  I post a screenshot where you can see an example of image with the desired noise reduction applied (right) and the same pictures, as he shows in the field of the library (left). Switching between the two areas (library and develop) results as a toggle of noise reduction.

  Dropbox - example.tiff

  
  

  Is there a way to fix this bug?

  
  

  Thank you.
  

  View generally develop - Fit is more crisp than the library or export, when there was enough noise reduction added to an image to give the impression of sweetness, and people complain that sharpening is not applied; However, in this situation through extreme noise reduction settings, an artificial coarse replaced fine-grained noise that seems to manifest itself differently according to develop Fit, and the complaint is that the library has no NR applied.

  More in detail, there are two questions here, both to the user, LR:

  (1) a user-hope that the No 1:1 to the point zoom is specific about the detailed settings.  It is not the case.  Years, there has been a warning of exclamation point on the detail settings section that says see things only to 1:1.  If a user doesn't see or ignores this warning and then their expectation wrong, as in this situation.

  (2) the detail of Luminance Noise reduction slider has been increased from the default value of 50 up to 100.  This has the effect of converting the sound of grain in an angular course texture, which is easily visible in reduced size except in the view to develop was inaccurate.

  In the next-by-side to zoom 1:1, the left panel is according to the user settings with the Lum-NR-Detail slider to 100, while the right has the cursor Lum-NR-detail set at the default value of 50, with all other parameters of the user remains the same:

  

  I would summarize what happens not as a bug but a different response from the develop-adjustment incorrect attended a different coarseness of the noise which is caused by an extreme environment of the Lum-NR-detail slider.  Since there is no resizing and not sharpness in export settings, I don't think that 1/3 bug has nothing to do with anything.

  It would be nice for the original poster (OP) to describe exactly what is wrong, after knowing the view to develop it is accurate if not seen at the 1:1.

• How to prevent echo over the noise reduction

  I had a dickens of a time trying to find how to reduce the echo that remains after the removal of the background noise. However, I do not give to the top and after playing with some of the settings, I believe that I thought about it! I use Adobe Audition CC (6.0). You'll want to follow the steps below as a means of noise reduction, not after it. So we prevent the echo over the noise removal, do not get rid of it... if that makes sense. Then, start with your original audio with noise, then...

  1. Perform normal selection of background noise and sampling procedures, it (SHIFT + P)
  2. Select all audio data (CTRL + A).
  3. Prepare to apply the noise reduction: Effects > restoration/noise reduction > noise (process) or CTRL + SHIFT + P
  4. In the window that appears, I played a bit with the three parameters (see image below):
     • (85%) noise reduction slider
     • Reduce by slider (approximately 40 dB)
     • In the "Advanced" section (you may need to click on the small triangle/arrow to decompress), the spectral decomposition rate (10%). It is this final setting that makes a HUGE difference!
  5. Put audio on the loop if it is a small clip and click the play button to hear a sample of the noise reduction applied.
  6. Adjust the three above mentioned settings until you get the desired effect.
  7. Click 'apply '.

  I hope that helps!

  

  Can I make a suggestion?  Although you're experiences were useful, trying to find a unique size of the entire solution "one pass" probably doesn't give the best results.  Basically, if you hear NR artifacts (the quality that you are referring to) any point you made too much noise reduction only once.

  As a general rule, you're better off doing 3 or 4 passes the very slight noise reduction, entering a new sample of noise each time.  For most 'normal' noise, it can also be very useful to increase the size of the FFT (in the Advanced menu) a parameter preset or so before grabbing each of these sequential noise samples.

• Adjustment with exposure adjustment brush cancels the noise reduction

  Hello

  I just noticed the following problem:

  (1) camera Raw 6.5; Bridge CS5 (4.0.5.11); Mac OS X 10.6.8; Mac Pro 3.1; Dual Quad-Core Xeon; 8 GB OF RAM.

  (2) start with a loud raw file (mine is a Canon 5 d II).

  (3) apply to noise reduction (luminance: 30;) Detail of the Lum: 75; Lum contrast: 0; Color: 25; Color detail: 50).

  4) go to the adjustment brush and set a nonzero exposure value.

  (5) apply the brush to the image and notice the effects of the noise reduction to disappear (noise returns).

  6) click clear all button to clear the adjustment brush and the noise reduction works again.

  This seems to happen only with brushes of adjustment with a nonzero exposure value (application of brightness or other settings do not seem to produce the problem).

  Anyone else seeing this?

  Thank you!

  There are a few known issues with the exposure setting local leading to overall appearance of the image changes, especially in the highlights.  The problem with the noise should already resolved with the ACR 6.6 release candidate (RC), currently available.

• How to get rid of the bubbly voice after noise reduction?

  After the noise reduction it is somewhat an echo so I used this method How to prevent Echo for the noise reduction to get rid of it and, now, my voice became very sparkling. No way to get rid of the bubbly voice?

  Which of the methods described in this thread that you use?

  If you read beyond the first post, you will find that many of us in complete disagreement with the working method first described - doing one pass with the sliders for NR and reduction in the value of values is a recipe for the sort of things you describe.

  Your best bet will be to return to your original file and repeat the noise reduction.  This time, playing in the past 4 or so light, rather than trying to do it all at once.  In the "Advanced" tab, set the size of the FFT to 2048, the NR slider at 20% and the reduction to 10 dB.  Apply the effect, then capture a new impression of noise with the size of the FFT to 16384 then 4096, and 8192.  You can vary the slider up and down like so requires, but each get subtle.

  Working this way should allow you to achieve your NR without echo or bubble effect you mention.

• Hearing (CC 2015.2) noise reduction does not

  IM on an Apple running 10.11.6 and hearing CC 2015.2
  recently, I have to obtain the reduction of noise at work at all without success. I work as usual by selecting an impression of noise, and then opening the noise reduction and I immediately get a massive pop. If I stop the preview and start it again I get the same thing. There is no preview adjustments either. any parameter there is no change in the preview. If I try and select noise only it isn't even a change.

  If I apply the settings there isn't even a change even with more stringent parameters.

  I have no idea what is going on here and I really want to use the tool.

  Thanks for any help. !

  Well I took a risk and just blew the whole directory to ~ / Library/Preferences/Adobe/Audition/9.0.
  Not sure what was bad or something has been altered after the last update, but this fixed the problem.

  Hope that this thread helps out someone else in the same place.

• The noise removed, now Audio is melodious

  Can I counter audio snoring? Once I removed the noise from the Hall, the moment sound of chirping voice through a bad telephone connection. I downloaded videos from before and after the noise reduction.

  Before:

  After:

  I'm afraid that you have rather exaggerated it...

  You would be better off removing noise is going smaller, to use a different size of the FFT for each passage, with reduction under each. With this kind of the base level, you will be much better served by using the highest size FFT it is for most of it, but it should also be a collar with a setting of low and medium. Also, don't forget that it's called noise reduction, not removal. Saw a small amount of noise actually remaining with the signal tends to hide many of the murmur and usually other more 'realistic' sound signals, if you wish.

• Cc of Lightroom export no noise reduction and sharpening changes

  I have recently updated to Lightroom from 5.7 to CC, but can not get the noise reduction and sharpening of changes to export. The files are imported from a D7200 of Nikon NEF files. After you change the image, I can see the changes in library modules and put at the point, but not in the exported jpg file. Any help is greatly appreciated.

  Thanks for posting the requested screen captures and ISO setting. You see more noise in the exported JPEG image file in the library and develop modules because you have output applied sharpening (sharpen: high screen). This is the case additional sharpening not present in the library modules and develop. ERGO: They will be different. Output sharpening should be used when reducing the size of the image with "Resize to Fit" checked. Each time an image is resized it loses the edge sharpness and output sharpening restores the details of contours in the small size file.

  Follow the instructions in deepakgahlot provided in response #1 and ensure that the export module output sharpening > sharpening for: is not checked. If you still have questions please download one of the files on Dropbox image or other file sharing site and post the sharing link.

• Noise reduction, clarity and sharpness of Vs masking

  Maybe I used too much clarity for the birds and noise reduction. Some recommend on dpReview, no noise reduction and now I tend to believe them. Recently, I tried using little to no noise reduction, little or no clarity, a lot of sharpness and about 40% of masking. This gives the details of good bird feather, and anything with less detail has little better bokeh and noise. In areas of low detail it seems to me that the masking reduced the noise caused by the sharpening, but it has less effect on the noise increased clarity. Is this true? If this is the case, birds, photography is better clarity used sparingly and selectively, as on the head?

  Another reason for all of this, is that once I read even a little masking degrades the sharpness but now I doubt that. Maybe LR which has improved over the years.

  Thank you

  Doug

  Reducing noise from luminance indeed (and the extended color noise reduction) tends to erase fine feather detail.

  I recommend:

  * lowered the noise reduction and if you are not using it, how the cursor nr.detail up crank - this will help maintain fine feather detail and is superior to sharpen detail to maintain details otherwise lost pen due to the reduction of noise.

  * a lowered sharpening in detail, to reduce noise and reduce the "need" to reduce the noise.

  * and sharpen masking to taste...

  Also note: exactly 50 masks all global sharpening sharpening room and can therefore be used in conjunction with noise reduction to smooth bokeh areas.

  And of course you can add sharpening or clarity locally too.

  I know that I have not responded to your question perfectly as asked, but I don't know what to say, then...

  Have fun

• Classroom in a book - CS4 - Lesson 6 - cannot get rid of the noise

  I'm on Lesson 6 version CS4 classroom in a book. I worked on the image with the mother and child, but I can't seem to get rid of the noise in the mountains and the sky. They look very grainy. I've followed all the steps exactly and even went through screen shots to see if any setting have been changed which may not have been mentioned. I compared my version to the version 'End' and they seem very different. The mountains and the look of the sky much better in the "End" version, although the mother and child look more exposed. On mine, the people look much more sharp, but the noise in the mountains is terrible and the sky is also quite grainy.  I redid this part of the lesson about 6 times, four times on my PC and twice on a MAC, but the results are always the same.  The sharpness which lesson you do at the end, while improving certain parts, the granulation in the worst of the sky and the mountains.

  This has been very frustrating.  Clearly something more was done with the image of 'End', which was not in the lesson.  Even if people, in my opinion, look better in my finished version, the mountains and the sky look terrible, and the background was the entire point of the lesson. Does anyone have ideas, what has been done to make the smooth background to the image of 'end '?

  I dug my copy of PS CS4 classroom in a book and went through the same lesson to see what results I got.  I can confirm that the noise reduction is not optimal.  See the example in the picture 'after ':

  

  Compare with the results of a 3rd party plugin noise reduction (in this case Topaz Denoise) using a standard preset:

  

  This version needs a bit of sharpening is to the people.

  In doing this exercise that I was reminded why I dislike the Classroom in a Book series.  It makes you go through the steps like a zombie, tell you what value to enter in each field, but it does not often do the fields. Certainly, as a reader, you are free to experiment, but which do not encourage lessons. And the fact that the results do not always match the book and readers are disappointed when the results do not confirm my opinion that the book is not encourage experimentation.  Perhaps a further reduction of noise was made for each channel in the Advanced setting of section.as described in the box of Lesson 6.

• Question output noise reduction

  Whenever I have apply the noise reduction in LR3 Beta 2, the settings will be displayed in the preview area in LR, but as soon as I export to JPEG, the treatment disappear.  It only occurs with noise reduction - all other treatments remains on the image.  Any help?

  I understand the confusion. This is a gap in low resolution

  displays that requires a lower resolution image must be

  generated to show you a preview. Lightroom 3 tries to give you a

  an extract which is quite accurate in using subpixel rendering, but

  Lightroom 2 gives you an overview particularly badly to develop which is

  a side effect of the way the preview is generated. He uses a much lower

  resolution interpolated to the version of the image display resolution

  for reasons of speed in the zoomed-out view. Often, this shows you

  more noise is actually there because you don't get the average

  of pixels you should get when zoom you back. Sometimes, however, as

  in your case, it shows you actually less noise than is really there.

  Both are objects of art of the choices made. Only when you zoom

  1:1 will actually receive you a correct rendering of the image taking everything

  the parameters of development into account.

• A way to be precise with the noise removal filter

  Hello! as the title says, I need to learn a method to apply this adjustment only to the tip inside areas of an image. as I'm sure you know, the filter options remove noise will do the job at the expense of the loss of sharpness if necessary. remove the most noise, lose clarity. It's a blur, actually. so, how can I quickly and accurately make a selection of the only areas of detail/edge of the image (the time factor is especially important if your dealing with a pretty complex picture with many lines - my case, actually)?

  With an image like this, I and just create a new layer with the noise reduction. Then, I use the brush on a mask tool to remove sections of the line of the layer with the noise reduction. It's easy with this, because they are all straight lines, and you can click the top of the line with the Brush tool, shift click down the line to have a very straight and precise line on your mask.
