Adaptive noise reduction filter only applying to parts of a clip

MAC 10.9.4
3.5 Ghz 6-core
16GB ram
AUDITION CC
PREMIERE CC 2014
This is happening over and over to me, along multiple projects and multiple clips.
I apply Adaptive Noise Reduction, and tweak the properties. It sounds great but then when I 'apply', the filter is only applied to about 50% of the clip.....meaning it sounds great when tweaking the filter, but after when it is actually applied, only parts of it will apply.
IE, If I have a 15 second and apply noise reduction.......It sill sounds while tweaking parameters. Then after I hit apply, seconds 1 - 4 will sounds great (filter applied) seconds 5-9 will sound awful like no filter has been applied, and seconds 9-11 will sounds great again, and 12-15 will sounds awful again.
There is def something wrong here., This never used to happen in CS6, ever. Only when switching to CC.

Hi,
I have little use for/of the adaptive version of the noise reduction filters only because I want it ALL cleaner, so here is what I suggest: I left a very-detailed posting about "batch processing" in which I outlined using the the process version in the Waveform Editor. Give that post a read Re: How Do You Apply Process Effects To Multiple Clips In A Multi-Track?
Let me know if you need more help.

Audition CS6 crashes while running Adaptive Noise Reduction

Hi everyone!
So that is the problem, I edit an audio file, run Adaptive Noise Reduction filter, and somewhere during the processing the computer just crashes. Sometimes it happens and sometimes not. I saw that computer showes up an alert message just before the crash but I wasn't fast enough to read what was written there. Recently I did a clean system install and have just some programs installed. Before system reinstall the problem was not there, although the program (audition) is exactly the same. What to do?

I run the pro version, but it's basically the same. I've got all the updates installed, but I haven't noticed it slow down at all. Mind you, this is a fast system anyway. But if it's crashing, then installing updates won't fix that; you need a fresh reinstall on an absolutely clean disc first. Okay, that's a pain - but look on the bright side; you aren't running Windows 8. Recently I wasted nearly a day of my life on that, and I'll never get it back. The basic rule about M$ OS's hasn't changed - it's only the odd-numbered ones that are worth bothering with, as a rule. And none of them are worth installing until the first service pack is issued.

Weird Banding with Noise Reduction Filter

Working on a night shot of a building and processed through ACR7.2 and forgot to reduce the noise - and opened in Photoshop. Went to Filter/Reduce Noise and immediately get wierd banding in the window blinds. This banding is there regardless of the noise reduction settings and could not get it to go away - See attached screen shot of before and after applying the filter. So I went back and opened the file again in ACR7.2 and applied the Noise Reduction there and bingo, noise level dropped and looked good with no banding. Looks like the Noise Reduction capabilities in ACR7.2 are way better than the Noise Reduction filter - but surely the banding should not be there; especially if images do not get processed through Camera RAW.
Running latest version of Photoshop CS6 (latest patches applied), Windows 7 x64 16GB RAM, Intel 4000 with latest drivers installed. Camera file was ACR2 from Canon 5DMKII imported as a DNG file - then opened in ACR 7.2
Before Image Opened in Photoshop before applying the Noise Reduction Filter
After Image in Photoshop after applying the Noise Redcution Filter
Seems like a bug to me
By the way, the screen captures are from the image viewed at 100%

The aliasing effect you're showing is obvious, but are you saying the noise reduction operation also changed the color of the image?
I didn't think so. Your "before" image appears several steps removed from your "after" image.
It would be best if you'd capture a "before" image of your entire display just before and just after applying the filter that causes the aliasing pattern, and also specifically describe or screenshot the exact parameters being provided to the filter causing the problem as well.
In general, if you're getting aliasing introduced into high detail / high frequency parts of your images, you might find it advantageous to work at a higher pixel count - i.e., change the output size in Camera Raw so that you're opening images at an upsampled resolution. That's the only way I work, and I find it advantageous to have more pixels representing the image while editing in a lot of ways.

Neato Video Noise Reduction Filter

Merry Xmas
A fellow filmmmaker has used the 'Neato Video Noise' plug in with pretty good success. Was wondering if anyone else out there has tried it?
I have some underexposed footage shot on a DVX100, (low daylight footage), which I tried tweaking with the FCP HSL Filter. But as you may know, the HSL Filter must be used carefully (sparingly), or it will cause grain.
Anyone know if Neato's Noise Reduction Filter works more efficiently?

Thank you

No, there are no built-in noise reduction filters.
There are a number of free and commercial solutions out there ... the free ones are obviously worth checking out but less capable (try TMTS Noise Reduction and Smart Noise Reduction), of the commercial filters http://www.neatvideo.com/ and http://www.revisionfx.com/products/denoise/ seem popular.

Encore 2.0 Noise Reduction Filter Information

Adobe Staff and Forum Members,
Would somebody please explain how changes in the noise reduction filter change video quality. It seems the standard setting is 30% and I don't have a manual with the trial version to understand what changes to make on order to best transcode older video. I'm waiting for my hard copy of Encore 2.0 now but in the mean time any information would be greatly appreciated. Have a great day!
Thank you,
Don

> How much time does a change in the noise reduction filter have on transcoding time?
I don't have any hard data to quote, but it's significant (and also depends on whether you use CBR vs. VBR 2-pass). But offhand, I'd say the filter will at least double your transcode time. You may find the results worth the wait...the output preview should help you to decide this.

Noise reduction filter???

Does anyone know of a high quality FCP-compatible video noise reduction filter for HD footage? Is there even such a thing?

All of the software that works with this does this... soften the picture.
The controls are precise however, and I've used it with really low light footage to advantage.
Denoise is a video noise reduction filter plugin for FCP google it... render is awfully slooooooo. Color renders faster. free download of demo with big red x thru all footage I think. Lots more controls.

Need Noise Reduction Filter

I need to reduce some Noise or at least Reduce Colored Noise in some night shots of the Aurora. In Photoshop there is a neat Noise Reduction filter that allows one to do this... but I can't find anything in CS3 or 1.5 versions.
Am I missing something here?
Is their a 3rd party software that will do this?

Will do... email me at [email protected] and give me your email (Soon as I'm going to kill that one... too much spam). I'll let you know. This is a huge project of remastering 17 hrs of Aurora footage... time laspse, color, levels... the whole works. May be months before I'm done.
Also... I just checked out their website. WOW...!!! Is it really that good? I'll be in heaven.
I see the Pro version lets you do HD Wide format... which I'll start shooting my projects in soon.

Noise reduction visible only in Develop area.

My Lightroom 5.4 for mac has a bug in noise reduction. The noise reduction is visible only in the develop area, and while switching to library it disappear. This affects also exported files and published files like flicker's one. I work with raw files taken with my nikon D5100. Is there any way to fix this bug?

Are you viewing these at 1:1 / 100% Zoom or smaller? Can we see screenshots of what you’re seeing at 1:1 zoom? Are you apply Export sharpening? Are you resizing smaller? Flickr does add its own sharpening, I believe.

Soundtrack Pro on the fly noise reduction filter?

The microphone I use for voiceovers has some fuzzyness that I always end up having to clean up afterwards by taking a noise print sample and then applying the filter. Since I am always using the same mic for this, is there a way to create a preset filter on the front end (as I am recording) so I don't have to go back and reprocess the noise reduction afterwards? Basically I am looking for a way to create a microphone profile and apply the filter on the fly so I can streamline my work flow.
Many thanks.

Why Noise reduction filter on adobe PS Touch does not work?

I use iPad mini and want to reduce noise on my photo, but it does not work event though I have moved the slider from 0 to 100. It tried with another app that is adobe ps express, and it worked well. Kindly, i need your helping to solve my issue.
Regards
Sigit
Note:
1. My device ipad mini with ios version 6.1.3
2. The app name is adobe photoshop touch

Good day!
As far as I understand this Forum is dedicated to beginners’ problems with Photoshop.
Photoshop is not Photoshop Touch, so you may want to post on the appropriate Forum for that application.

Noise reduction won't display properly in LR 3.4.1 Develop Module

I encountered this issue first time last night - noise reduction will not show in "Fit" view of the Develop module for pictures that have a graduated filter applied as well. Having said this,
- The pictures display correctly in Library Loupe view (Fit and 100%)
- The pictures display correctly in Develop module when zooming in to 100%
- The pictures display correctly in Develop module when clicking in history on Luminance smoothing (first picture). Selecting the next step in the history, Add Graduated Filter, displays the picture without noise reduction (second picture - I tried on a virtual copy the other way round - first have a graduated filter and then apply noise reduction, but doesn't work either. Noise reduction just won't display in Develop module / Fit View once a graduated filter is applied as well.
Has anyone else seen this behaviour or, even better, found a solution? I already tried purging the raw cache, no success. Working on Windows 7 / 64bit.
Thanks,
Andreas

Jeff, I had difficulty understanding this same issue as presented at the link I posted above. With my low-noise Canon DSLR RAW images I simply couldn't see the onscreen rendering issues they were talking about. It even appeared this might be unique to Mac platforms and Windows 32 bit OS, since my Windows 7 64bit system didn't appear to have this issue.
Following suggestions to shoot a picture at -4 F stops and then increase exposure by +4 F stops in LR helped me get a better understanding:
http://forums.adobe.com/message/3857767#3857767
Granted this is an extreme shooting situation, but it helps demonstrate what happens when using exposure, fill and HSL sliders to increase exposure significantly (+2 to +4 EV) in specific areas of the image. Now you have noise that will be visible in smaller exported scaled images, perhaps even those sized for posting to the web.
The issue is at lower ISO settings (camera specific), view sizes less than 1:1 have no noise reduction applied (Mac & Windows) or sharpening applied (Mac & Windows 32). There appear to be platform differences in the way sharpening is applied, because on my Windows 7 64bit system sharpening is applied at all ISO and all view sizes including "fit" view, but noise reduction is only applied at higher ISO settings – the same as all others have described. I wanted to point this out since it is one of the reason I had difficulty duplicating what the OP was seeing.
We know sharpness and noise reduction settings interact with each other, so it is important to have both applied in the onscreen image to determine their affect. Using images with additive Exposure, Fill and HSL slider settings approaching +2 to +4 EV, there is simply no way to see accurate rendering without both noise reduction and sharpness applied at all view sizes, including “fit” view. This can occur with low ISO images, not just at some predetermined camera specific high ISO where noise becomes predominant.

Noise Reduction wont apply to track

I am having a rather difficult time getting a audio track i have sent from FCP to play nicely in soundtrack. I sent the audio file from FCP as a audio file project, it opens up, i set my noise print, and adjust the reduction accordingly. Then once i try to apply the effect it will act as if the reduction action was applied but it doesn't actually apply to the track. I did select the area i wanted it to affect and i get nothing. I tried to save the reduction as a Script and apply it to the track in FCP and i end up with the same result. The part that is confusing me the most is if i select the Reduce Noise from the action list and play the track through the reduction hud it plays correctly it just wont apply to the track. Any help would be very much appreciated.
I am running SoundTrack 2.0.2 and Final Cut Pro 6.0.5

Hmm, this might sound obvious, but did you "Save" the audio file project after applying the noise reduction filter? You have to save the project before it will update in FCP. Also, after you apply the filter to the file, the noise reduction should show up in the actions list, before you save and flatten the project.

Noise reduction only on shadows

Would be great if we had noise reduction adjustable only on shadows in camera raw & LR ?

Yes. But it would be better if we had an easy way to select only shadows, so we could then apply any changes to them (noise reduction, color, tone, ... ).
Ditto for highlights, and all the dark blue stuff, and all the ... stuff.
Nik software supports this via U-points, and I hope Adobe invents a similiar auto-masking technology that blows U-points out of the water .
Cheers,

Noise reduction not applying to beginning of clip

There's a bug in Premiere Pro which results in the hiss reduction or certain audio effects not being applied to the first 2-3 seconds of audio when exporting.
After looking this up on the Adobe forums I found other people with the same issue, and they were advised to edit the audio in Audition and reimport into Premiere Pro. I am having the same problem in Audition however.
I capture my noise profile, apply the adaptive noise reduction (or dehiss or whatever) and the audio sounds fine in the program. But when I export the first 2-3 seconds have the original hiss and you can then hear the effect kick in.
Can anyone help?! I offered to start doing video for my work and this is driving me up the wall.

Adaptive Noise Reduction is just that - adaptive. It identifies sources of dynamic noise over time, then reduces them.
If your clips don't have a few seconds before the in-point with which to apply the algorithm, you can often just copy/paste a few seconds at the beginning of your recording, run the effect, then delete that section. Dropping a marker after you paste the selection (while it's still selected) will make it simple to select that range again for deletion.
Otherwise, you might want to try the more manual NR tools. You'll have more control over what's identified as noise and how drastically it's reduced, and can make several light passes for better results.

In-camera high ISO noise reduction & ACR

I've been involved in a discussion over on DPReview where someone believes that, when shooting with a Nikon dSLR (in this case a D7000, but the model isn't really important) high ISO NR is automatically applied in-camera directly to the raw file, and this will be carried over to any raw conversion software, including third-party software such as ACR/LR.
Now I do agree that even with NR switched off, Nikon do automatically apply some limited NR to high ISO images in-camera, but I'm pretty much 100% certain that this is not something that ACR would interpret, and so it would not actually have any effect on the appearance of the raw file when it's processed. In fact, if the high ISO NR is somehow embedded into the raw file, that would go against my whole concept of how a raw file works in a convertor such as ACR! Surely any "default" high ISO NR is just added to the proprietry part of the EXIF, and is therefore only factored in when using Nikon conversion software (ViewNX, etc)? Otherwise, the file could not truly be considered to be 'raw'.
I think I'm right, but wanted confirmation from some of the experts on here! And of course, I'm also quite happy to be proven wrong!

By the way, the reference I found for D7000 shows that the High ISO NR can be disabled. See this page: http://www.imaging-resource.com/PRODS/D7000/D7000A7.HTM
What camera do YOU have, Molly?

Hi Noel,
Wow, I'm impressed with your efforts here! Your point about blurring being a potential sign of whether or not NR has been applied to the high ISO raw files is a good one, and I agree that, based on that thinking, the examples you've found don't really seem to show much evidence of that, particularly the shots of the focus/resolution target.
I do have a D7000; I replied as such back in post three ("yes I do" in response to your question "do you have such a camera?"), but I can see how that may not have been as clear as it should have been! I'm going to try some test shots myself to see if I can pick out any evidence of softening/blurring that may indicate NR being applied during the processing of the raw data. However, unfortunately my PC is currently being fixed as I've been having some hardware issues, so that testing won't be happening until I get it back (hoping within a week, missing it already).
Regarding your reference that indicates that high ISO NR can be switched off, yes it can, but apparently only up to a point - here's what it states in the Nikon manual (and what has in turn sparked off this discussion over on DPR):
"High ISO NR - option: off - Noise reduction is only performed at ISO sensitivities of ISO 1600 and higher. The amount of noise reduction is less than the amount performed when low is selected for High ISO NR" (as the article indicates, there are three options apart from off: high, normal, and low).
As I've said previously, my understanding was that all of that had zero bearing on the raw file once it was loaded into ACR: regardless of any NR settings applied in-camera, either by the user or by Nikon bypassing the user, they were all thrown away by the Adobe raw processing algorithms, as are things like picture controls, sharpening, contrast, etc. But following my recent discussion, I started to wonder if my understanding of the raw capture process was incorrect, hence this thread.
Thanks again for your work here. Above and beyond the call of duty!
