Noise reduction for VHS source

I am trying to edit video clips captured from VHS tapes made years ago. I wonder what is the best practice, or a quick and easy way to de-noise the video, particularly the wave-like video stripes at the bottom of the screen.
Thanks!

Paddy,
I am not a big fan of Scaling Up, but with the VHS material, that I have worked with, the adjustment was about what you needed, and worked fine. With Motion>Position, one can effectively "crop" the noise out, at about 1/2 of the Scale, as one is Scaling the total vertical (and horizontal), so with a nudge down, to the top of the VHS Frame, the noise is "cut off."
Good luck, and glad that it worked.
Hunt
PS - with overscan on a TV (even newer HD units still have a bit), more of that noise will likely be cut off, except for broadcast monitors.

NOISE reduction for Vocal Track?

Hi,
I'm wondering whether will you use the Noise Reduction for Vocal Tracks?
Why i question it?because, most of the Home Recording Studio doesn't have a Proper Room Treatment, So might make the Room Noise recorded into the Vocal track...For that,will you use the Noise Reduction to solve the Noises?
appreciate to the helpful thread you've provide

but if the noise is... a sound that has been recorded in the same track with the
voice... you cannot do anything
Sure you can.
if the room is not separate are there is a ambient noise recorderd such as Phones
rings or Child crying
RX can deal with this too.
you can also try to silence every free space between the vocal parts...
because the sockets of breath voice will be certainly compromised
Not a problem with noise print removal. We're only removing/reducing the noise print, not any wanted signal.

Noise reduction for 32bit images acting totally different

The noise reduction behaves totally different when used for 32bit images in ACR.
It appears like it is applying some kind of strange blur or glow effect instead of working like expected from 8/16bit material.
Can anybody confirm this and is this intended behaviour?

How did you get your raws into HDR?
Did you use raw files in ACR? Did you set the sharpening and noise reduction to optimal parameters in ACR on the raw files BEFORE going into HDR Pro?
You should...I've found that it's important to optimize the raw files in ACR/LR before actually processing the raw files into HDR Pro...you need to realize that once the raw files are demosaiced, the best place to apply sharpening and noise reduction has been bypassed?
Yes, a 32-bit TIFF opened in ACR 7.1 will not have the same sharpening and noise reduction opportunities once the original raw files have been processed. I've found it's useful to apply all ACR image optimizations (including tone, color and sharpening/noise reduction) to the raw files BEFORE doing a conversion to HDR Pro...
And yes, the noise reduction settings in 32-bit in ACR 7.1 are _VERY_ tweaky (meaning you need to be very careful on the settings).

Poor quality noise reduction for Canon G10

I recently bought a Canon G10, and I am disappointed at the quality of RAW conversions done by ACR/LR at anything approaching a high ISO. The out-of-camera JPEGs show much superior noise reduction to what I can get from RAW files, no matter how I tweak the noise reduction settings.
At ISO 80-100 both look essentially identical.
At ISO200 JPEGs show less and tighter grain than I can manage with RAW (unless I nuke the details with luminance reduction), but both are still very good.
At ISO400 ACR/LR's RAW conversion starts to fall apart. Chroma NR in RAW is still handled well, the grain size in RAW is much larger than the camera's JPEGs. I need to apply a lot of luminance NR to reduce the RAW grain to match the JPEGs, and when I do that I lose a lot of detail. And even then, the larger grain isn't as attractive as the JPEG.
At ISO800 this problem is even worse. Big ugly blobs abound in the RAW conversion. The JPEGs don't look great, but they're very usable, especially if you're willing to dip the shadows a bit to hide the worst of the noise.
ISO1600 is interesting. The JPEGs don't look great; there's a healthy amount of noise, and NR kills a lot of fine details. But the image is usable for 4x6's or sometimes even an 8x10. But the RAW files are awful! Even cranking chroma NR to 100, there's color noise to be seen. And even with very careful use of luminance NR and sharpening I can't results that are anywhere close to JPEG's level of detail and noise.
I understand that P&S cameras like the G10 are very noisy by DSLR standards and so this might not be a focal point of ACR/LR development, but I'm surprised and disappointed that the JPEG engine in the G10 can do a better job handling noise than ACR/LR. I guess my hope is that ACR/LR will at some point offer improved NR so I can create photos using RAW that look as good as JPEGs straight out of the camera. As it is right now I'm in the unfortunate position of shooting JPEG at high ISO to get usable noise performance. My dilemma is whether to even bother shooting RAW+JPEG when this IQ might be the best I ever get from ACR/LR for the G10.
I suppose my favored solution would be to either implement or license NR technology that matches NeatImage/NoiseNinja/NoiseWare. That feature alone would be worthy of justifying a 3.0 version for me. :)

Jeff, I won't debate that the output from the G10 at ISO800+ is poor. It most certainly is! And I know that simply eliminating the scads of noise in a G10 high ISO shot won't restore the detail the noise killed in the first place. But with every other camera I've used with ACR and LR, the color noise slider eliminates all color noise at or before the "100" setting. So I was surprised when that wasn't possible with the G10.
I don't currently own a camera that puts out an image quite as noisy as the G10 at ISO1600, but what about the A900 at ISO6400?
http://www.imaging-resource.com/PRODS/AA900/AA900hLL6407XNR.HTM
Or the 50D at ISO12800?
http://www.imaging-resource.com/PRODS/E50D/E50DLL12807XNR.HTM
Both of those are horrifically noisy. Worse than the G10 at ISO1600, I'd say. But those cameras certainly aren't crap. They just offer ISO settings higher than some consider acceptable. But then again, some people consider anything higher than ISO200 on a 5D unacceptable, so it's obviously all relative. Point being, I would expect ACR to do the best job it could for any camera it supports, not just the best job it can do for only some of the cameras it supports.
In any case, I want ACR to be able to remove the color noise from my G10's images, just like it can with my other cameras. I know the images are sub-standard when measured against a DSLR, but at least to my eyes, even very noisy images can look decent in small prints so long as there aren't big color blobs all over the place.
As for the luminance noise, I'm happier to live with that. I'd be happy to eventually pay for a LR upgrade that gives me NR similar to what the high-end third-party apps do, because that feature would make each of my cameras geniunely more useful--and retroactively! But a simpler request it seems is to recalibrate what "100" means for the G10. At least then I could dispense with the JPEGs and still make an 8x10.

Very neat algorithm for noise reduction for high ISO

Hi travojed !
Thank you for your message
I came to the conclusion that the high level "Median" (or "Dust&Scratches") destroys parts in this algorithm.
And it seemed to me that the best result (when the contours remain sharp) will be if, instead of a "median" using the Topaz Denoize (Raw-moderate), because Topaz protects the sharp contours in this algorithm.

I do not recommend using a constant value "Threshold" because at different values of the ISO get different noises

Noise Reduction for Premiere CC 2014

Before the new release, I have used Neat Video for noise reduction. Unfortunately, this plug-in is not working well with CC 2014. The only native plug-in I saw was to create noise, not reduce it. Does CC 2014 have a noise reduction tool?

The Mercury Engine can use OpenCL in Radeon cards. That being said, the R9 M290X is not in the list of currently supported cards, and therefore the Mercury Engine should default to Software Only.
Adobe won't add the R9 M290X to the list of supported cards until they can fully test it. So hopefully they will add it in a future update (*fingers crossed*).
Until then, you may be better off with a maxed out 27" iMac which has the GeForce GTX 775M, which is supported. It will no doubt perform better, and yes it will be like a hot knife through butter.

Video noise reduction software?

Sorry... but I've asked this question in the Tiger OS forum about video noise reduction for iMovie HD 6 and/or QT files but haven't got far with it.
If anyone on this forum has any suggestions about what I could use to reduce visual noise - basically transferred film grain in digitisation, I'd really appreciate it
(better still a free software download or trial would be even more appreciated)?

I'm not aware of any free good denoiser.
Neat video has a trial, but I think it's either watermarked or limited to SD. But it is really good and the trial will give you an idea of what iyt can do and whether it's worth the outlay for your purposes.
Another option is Adobe After Effects. A bit of a learning curve, but they have a trial.
Good luck.

Noise reduction makes robotic voice

I have been using Noise Reduction feature on "Audition" with no problems. When I have upgraded to "Adobe Soundbooth" I have an issue with this feature. When I turn it on I hear robotic echo of the voice no matter what the parameters are, even if the slider of parameters is on the 0 point (no noise reduction at all). Furthermore, it makes no difference if I am doing it with noise reduction profile or not.

I tried using noise reduction for old recordings namely background hiss...then I discovered the audio effects work better for this...called "remove hiss" and also in the simple effects "Parametric" called "Under a blanket"

Noise Reduction Software

Does anyone have any strong preferences for a 3rd-party noise reduction app? I have several images taken at ISO 1600 with way too much noise. I know that I can download trial versions of several apps & try them. But I thought I would inquire from those of you that have experience in this area. Thank you.

I have been a part time pro photographer for about 25 years with a lot of amateur clicking before that. I used Photoshop from version 3 to CS3. In the past few years I have moved exclusively to video. My needs for still photo editing have dropped a lot. I do pull out stills from videos on occasion, but I'm not doing anything very fancy to them.
I do still do noise reduction though. I do that in both my video editing app (Vegas Pro 9) and CS3. Well, I just upgraded to Windows 7 64 bit and Photoshop CS3 refuses to install. So, I just bought and installed PSE8. It works just fine in Win7-64.
I installed the exact same plugin from PictureCode to run Noise Ninja in PSE8. It works just the same as it did in CS3. It works very well too. Most of the reviews I've read over the years usually put Noise Ninja and Neat Image at the top. They both work well and better than the rest. Either should work well for you.
I never used Neat Image (other than a trial test) and liked Noise Ninja a tad better. (I found it easier to use.) However, I do use Neat Video with Vegas Pro. That's the same company's noise reduction for video editing. I'm very happy with it too.
Thanks,
Clyde
PS - The #1 tip in using any of these is to don't over do it. Things can start to look artificial very fast when these are cranked up too high. With really bad noise (like your 1600 iso pictures) you tend to want to get rid of all the noise. Doing so can often ruin what the picture is all about.

Disabling Sharpening and Noise Reduction

Hello. I have Lightroom 1.2. I have over a 1,000 images to process. How can I disable sharpening and noise reduction for all of them without having to click that little detail box for each of the images. I use Noiseware for noise reduction and Focalblade for sharpening. If there is something in a folder within Lightroom I can delete to remove sharpening forever, please let me know. Of course, I want to perform the other corrections in Lightroom as necessary. Thank you.
Francis

Jao, Thank you. I have asked this question elsewhere before. I have recieved replies, maybe I did not follow the directions properly, but they never worked. The sharpening would be disableduntil I went to make another correction. Then back to sharpening Lightroom would go. Your way, sharpening is disabled for all the images and stays that way. Thanks again.
Francis

Noise reduction did nothing - no instructions for the process

I entered noise reducer in the help menu and "what's new in imovie comes up" - I am looking for info on the process to apply noise reduction and nothing applied even two layers down in what came up in "what's new in imovie".
I have bought the book iMovie HD 6 & iDVD 6 and it does not give direction on how to apply. It does say page on 157, "this effect minimizes white noise, crowd noise, and hum - but nothing else - no directions on how to apply!
My audio clip is selected in the time line and if it is as simple as selecting the apply button in audiofx, then select noise reduction, then select apply - IT DID NOTHING.
Is this how it works for application and out come?
Can anyone help,
jim

No, but the Help menu in iMovie does:
To add an audio effect:
Click the Timeline Viewer button (shown above).
Select the audio clip or clips you want to add an effect to.
Tip: To learn how to select multiple clips, see "Selecting clips" below.
Click the Editing button, and then click Audio FX at the top of the Editing pane.
Select the audio effect you want from the effects list.
Adjust the settings for the effect.
Different controls appear depending on the effect you select. For example, if you select Reverb, you can adjust the intensity of the reverberation by choosing a reverb style and dragging the Less/More slider.
Click Preview to hear the effect.
To stop previewing the effect, click Preview again.
If necessary, repeat any of the above steps until you have the effect the way you want it.
To add the effect to your selected clips, click Apply.
When you add an audio effect to a video clip, iMovie automatically extracts the audio from the clip. The extracted audio with the applied effect appears as a separate clip in one of the audio tracks in the timeline viewer. If you want to add multiple audio effects to the same portion of video, be sure to select the extracted audio clip to add the additional effects to.

Noise Reduction question for Aperture

I recently purchased my first iMac (after years of being a windows user) and decided to try out Aperture (to use with Photoshop Elements 10 as an outside editor). I am basically an Olympus user and like the way Aperture handles the Olympus ORF RAW files a bit better than Lightroom (which I have used since it was released).
Anyway, I do think that Lightroom did a better job of handling/adjusting the noise in the higher ISO Olympus RAW files than Aperture - again just starting with Aperture.
2 Questions:
(1) Am I missing something or is the only Noise Reduction controls in Aperture the two sliders that come up in the Inspector column?
(2) What is a good plug in for noise reduction that works with Aperture?
Thanks, Steve

Is There A Noise Reduction Plug-in For FCP?

Wondering if I could find a plug-in for FCP5 or Color that will reduce the noise shot with high ISO in low light. Does anyone have a suggestion. Thanks!
Message was edited by: sburst7

I have found the 'Noise Reduction' in the CHV repair collection for FCP to be the best out of anything that I have ever tried. The noise reduction is fantastic and the sharpness loss is the best out everything I have seen.
http://www.chv-plugins.com/cms/Fx-Script/Repair-collection/Repair-collection.php
The default settings can be a little excessive, I almost always end up with a setting of 10 and 15 regardless of the footage.
Also, you can try grain reduction inside of colour - pair it with a vignette and alpha blend to limit it to specific areas.
Cheers,
Liam.

Is noise reduction due for improvement

probably get a "who knows?" but I am thinking of getting Izotope's RX2 which is quite a bit better/easier to use than Audition's noise reduction system. However if there were improvements in the wings for Audition I'd hold off til the upgrade and check that out. Any news?
Greg

Simple answer is 'I don't know'. But you should bear in mind the following - which is that the advanced version of RX2 is three times the cost of Audition, and I'd say was worth it; some serious effort has gone into it and it works stunningly well. With the best will in the world, Audition's noise reduction simply isn't in that league, and it's unlikely ever to be, I'd say.
But with care, you can get exceedingly good results from Audition's NR - although you have to put quite a bit of effort, and multiple passes to do it. With RX2, you can get better results in one go - but I'd say that you really need the (expensive) Advanced version to do so. One thing that RX2 definitely does better is to deal with threshold results in a more sophisticated manner - which means that you get less issues with reverb tails, for instance.

Noise reduction / adjust amplitude not available for mono tracks.

Hi,
If there is a better group or forum for the following questions, please let me know.
I am presently performing the sound editing and mix for a feature using version 3.0.1 of Soundtrack Pro. Though I am mixing using the surround feature, I have chosen to only use the center channel for dialog, and the front right and left speakers for everything else.
Furthermore, the picture editor (who is in a different state) sent me mono dialog tracks (he first sent me location and ADR on the same stereo track, which I could not separate for elimination or proper levels) and stereo tracks for the effects and score. The two problems I am running into are:
1. I am unable to access the noise reduction tools for any of the mono tracks. The individual stereo tracks allow me to do this. What appears to be going on? Is there a workaround?
2. Similarly, I am unable to access "adjust amplitude" under the same circumstances. Again, the stereo tracks are fine.
Any assistance would be much appreciated!
Kind Regards,
Andre

No, although ACR v4.1 does apply some baseline noise reduction to many raw files, I do not think that it applies any default NR to TIF files. Lightroom v1.1 does not apply any noise-reduction to TIF or JPG files by default, at least as far as I've noticed, so I believe this will likely carry over to ACR v4.1 as well. Of course you *can* turn the NR sliders up from zero and then it will! In any case, you'd be advised to test that theory yourself just to make sure, before designing a workflow around that assumption...
