Premiere CC 2017 Adaptive Noise Reduction Delay Issue

[JesseMS42]

Hi Everyone,

I edit a lot of interviews and often the footage that is supplied to me has background hissing noise. When I apply the Adaptive Noise Reduction or the DeNoiser effect to a clip there is about a two second delay after I export before the effect works.

I've tried extending and lowering the volume, I've tried putting all the clips that need it on it's own track and using the track mixer to apply the effect, nothing seems to work.

I know I can do this in Audition but when it works in Premiere after the delay its easier, and I think it sounds better.

Does anyone have any suggestions? Am I exporting it on the wrong settings? Is there something I am missing?

I know this has been a problem that has plagued lots of people for years, I don't know why Adobe has not fixed it yet.

Thank you!

Ha, I LITERALLY just made a video on this for my next course at PluralSight (but it's not up for another week or so!). Anyway, here's the cheat:

1. Add the Adaptive Noise Reduction effect to the clip but make sure the clip has about 1-1.5 seconds of audio BEFORE you actually want to hear any of the audio (you might need to make it a J-cut or extend the clip longer from the beginning). Don't worry, we'll fix this in a second)

2. Add a Volume effect to the clip AFTER the Adaptive Noise Reduction effect (yes, it will look like you have TWO Volume effects on the clip, the original fixed one plus this second one we just added).

3. Lastly, keyframe the volume using this second Volume effect. Working backwards is probably easiest. Drop a keyframe a few frames before you actually want to here the audio (probably where your original in point was if you lengthened the clip). Then move back a few frames and drop the Volume down as low as it goes (like -287db or something).

Voila!

This works because we're changing the order of effects. First, it's using the original volume levels to adaptively remove the noise, THEN we're key framing the volume at the beginning to get rid of any leftover ambient noise at the start.

It seems tedious but once you do it once, it's really super quick and easy. Hell, you can save this as a preset!

Hello

I have the same problem

I did try to add a volume effect from the effects panel - just typing Volume and then dragging and dropping it on top of the sound clip that I extended as you said to do - but I do not see a second volume added on top of the clip, so I cannot lower the volume if not affecting the original clip. What am I doing wrong? Is the video ready to watch now?

thanks

Can you attach a screen shot? As soon as you drag the Volume effect onto a clip and then look at that clip's settings in Effect Controls, you should be seeing two Volume effects. Just want to make sure your set up is correct.

[longopongo]

I figured out what I was doing wrong, I was not putting the key frames correctly

thank you for your concern though, I really appreciate it

OMG you have to do all that? Ugh...I wish they would have never changed the noise reducer. The fact that you have to do all this rigmarole just to get an effect to work means the effect was bad from the start.

I agree.  Adobe is making a fortune, so I think a little overtime for some engineers to make this work after it was fine is the minimal right thing to do for people paying Adobe $20 to $50 per month.  Real shame.

Note to Adobe developers:  read Daniel Kahneman's studies of LOSS AVERSION.  It is much worse in intensity for a consumer to lose something they had than to pine for something they one day hope to have.  Lesson:  don't remove features that people like myself are using on a daily basis to make a living.  Or should I switch back to AVID now that it's the same price.

[josiahm29169243]

Also it doesn't seem to work. This why I hate using work arounds for simple programming errors.

[josiahm29169243]

Never mind I got it to work. Thank goodness. Still Premiere Pro please fix this horrible effect.

I'm with ya

I'm not clear how to do this at the beginning of a sequence. I did the steps as you suggested, and the noise is now gone by the time it gets to the part of the clip I care about, but it means that there are a few seconds of nothing at the beginning of the sequence. If I trim it, the noise comes back. Do I have to do something else to sorta pre-render (I'm sure that's not the right term, but I don't know what to call it) so that it remembers the noise-reduced audio when I trim the sequence back to what I want?

[jasontcox]

This is where workarounds start to show their cracks! This is one of the annoying parts about the Adaptive Noise Reduction. Are you ok with having 1-2 second of black at the beginning of your timeline? If not, you can try the Render and Replace command (found by right clicking the clip). This will replace the clip in the timeline with a new one with the burned in effect, then you can trim off the first second or two.

But at the end of the day, the BEST recommendation I can give it learning the noise reduction process in Audition.

Applying noise reduction techniques and restoration effects

Or if you really want a PRemiere solution, try Crumpepop’s Audio Denoise plugin or Izotope’s RX6!

I actually tried the "Edit in Audition" trick. But all the tutorials and help pages I could find stopped short of explaining how to get the edited audio back into Premiere Pro. E.g.:

• Editing audio in Adobe Audition
• Audition is the Secret Weapon for Video Editors — Video Review & Approval

One forum thread I found (Why can't I export edited audio from Audition back to Premiere Pro? ) said that you just Save and the changes will be reflected in the PPro sequence, but I must have not done it right, because no matter how many ways I "saved" in Audition, nothing changed in PPro. I could export to a WAV file and then import that into PPro and put it on the timeline, but that would break the nice link with the video track, use more disk space, and probably a number of other downsides.

No, I'm not okay with having black at the beginning, especially since it seems that in my case 1-2 seconds is not enough - it takes 3-4 seconds for the noise to disappear. The noise on the video I'm working with (an hour-long Bible teaching) isn't even very extreme - just a bit of 60hz hum and a bit of white noise from a fan - so I'm not sure why it's so hard for the ANR to figure out. I'm currently trying to encode setting an in point where I actually want the video to start, but I don't know if it will use the 4 seconds before the in point to get its running start or I'll hear noise at the beginning. I ran the encode last night, and the log file says it completed successfully after over 3 hours, but the resulting file has zero size, so I'm trying it again now.

Although ANR is a little better than picking a sample to make a noise print (because my camera's auto mic level allowed the noise to increase during pauses in the speaking), I would have been okay with the noise print method. But apparently that effect is not available in PPro but only in Audition, so I'd still need to figure out how to make the round trip.

[jasontcox]

Something must be off in the workflow, because if you take a clip in a Premiere timeline and choose "Edit in Adobe Audition" it INSTANTLY creates a duplicate of the audio clip in the timeline (with the words "Audio Extracted" tagged onto the end of the file name of the new file) and actually sends that duplicate to Audition. So then, when you do anything to the clip in Audition and hit Save, it's instantly modified the clip back in Premiere. I've done it a thousand times

I will say that if you have a very long clip (like an hour as you said), it might take a bit longer than usual to save and update, but it should work!

[OsakaWebbie]

A followup to my previous post, for the benefit of those reading later:

It works fine to just leave a few seconds extra at the beginning of the sequence and setting the in-point where you want the final rendered/encoded file to start. The complicated procedure of adding another volume effect is not necessary as long as you choose "In/Out" instead of "Entire Sequence" in the media encoder. ANR will use the clip content prior to the in-point to "get a running start".

[jasontcox]

I mean, that works fine if you only need to apply the ANR effect to ONE clip that starts at the beginning of your sequence. But if you have 4,862 clips and you want to apply ANR to many of them, then that won't work.

[davidl77500128]

I really hate this! It's so fiddly! I have a long file that I want to cut up, remove sections and remove awkward pauses. I'm really struggling with adding the second volume effect and getting it in the right place.

Surely there is an easier way?!

Ugh, I hate Premiere Pro sometimes (sorry, rant over!)

[tsu_fum10291677]

This isn't a solution to be honest.  It is extra workflow we have to take until ANR works properly.  Truth is: it should work right away. When I realized the adaptive Noise Reduction took a few seconds before it worked, I already knew what needed to be done and add a few seconds up front to let ANR kick in but the biggest frustration was how it "kills workflow." For each sound that needs reduction, this method has to be applied. Guys it is not a solution.  It is a workflow killer that only leads to frustration and wondering where is the solution.

I only hope an update will take place that will eliminate this workflow killer once and for all.

[SF Bay Film Editor]

agreed - a workflow killer is a creativity killer.  folks will go elsewhere...

[TomC93]

I agree, this is a huge error on adobe's part.

Have you guys tried using the 'obsolete' (although I'm finding more and more often that most of the 'obsolete' effects still beat some of the newer ones) DeNoiser? It worked like an absolute charm for me!

[jmuzyka]

This is a hideous waste of time on something that should be fixed.  In older versions it worked fine in my experience.  This workaround seems tedius and you better know about it going into the edit because once you've edited the whole project there likely won't be room for heads and tails on every audio clip.

Shaking my head over this.

[jasontcox]

Ha, Im 100% with ya. File a feature request! They'll eventually hear us!

[SF Bay Film Editor]

You're right on.  Things like this are CREATIVITY KILLERS.  Not a good branding device for Adobe....

[zain_JA]

hey so i did exactly that..and it didn't work for me.. all it did was push back the noise.. the piece i extended was silenced due to the key frame but when the real audio started the adaptive noise still started with the hiss. i managed to remove the hiss at the beginning by simply lowering that frequency in the graphic equalization effect

[stephenseagull]

This workaround works. Thanks
