Premiere CC 2017 Adaptive Noise Reduction Delay Issue

  • January 5, 2017

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!

    I understand it needs to analyze the sound to determine the noise before it can reduce it.

    But why not make it like the stabilize effect? You apply it and it looks at the entire clip in the background, then applies it.

    Maybe it takes a little time, but it's certainly quicker and more effective than adding 3 seconds to hundreds of soundbites.

    My 2 cents.

    Agreed, jblo. It doesn't even need to look at the whole clip - just looking at the first few seconds would suffice. And if it did that, it would work even on clips that don't have any extra on the front even in the original source.

    By the way, I just got a notification of Albright Productions responding with their workaround, but "View the full discussion" link goes to a different thread ID (https://forums.adobe.com/message/10384457) which doesn't exist, and the response is not here either, even though their profile says they responded on this thread (see https://forums.adobe.com/people/Albright%20Productions/content?filterID=participated). Weird. Anyway, their method sounds even more complex than other workarounds proposed - two round-trips of exporting, importing, and replacing audio.

    I ran into this yesterday on a video. I ended up rendering out just the VO as a wav file and then pulled it into Logic to process the HVAC noise. Rendered out of that and back into Premiere. The Adaptive Noise Reducer is a decent tool once it gets going, but that 1-2 seconds to start up is a dealbreaker. I appreciate all the creativity into the workarounds, but we shouldn't have to do that. Render and replace is NOT a solution either. Adobe needs to fix this, either with an "Apply" or "Process" button that applies the effect non-destructively. That's also one of the problems I have with the "Audition" workflow. Hitting that "edit clip in Audition" is dangerous. It's very clunky to "go back" if you make a mistake or aren't getting the results you want.

    Agreed we shouldn't have to do this but the method that jasontcox invented / explained works very well and non-destructively all within Premiere. I used longer handles than 1 - 1.5 seconds but that's the only variation.

      Shame on you Adobe

      So if the audio track mixer with denoiser isnt working for you, give this a try.

      >Apply denoiser to entire track with noise using audio track mixer.

      (this should now reduce noise on all clips apart from the first which still has a 2 second delay)

      >Add a few seconds of noisy sound before your first clip.

      >Apply a volume effect from the volume pannel to this noisy sound clip. (not the normal volume controls)

      >Reduce the db until silent

      I didn't know you could apply effects with the mixer...

      I did it clip by clip and extended a few seconds ahead of every clip, then did a volume effect to mute the handle after the adaptive noise reduction filter.

      I just learned that you can apply the "adaptive noise reduction" effect to the whole track in the Audio Track Mixer window.  That gives you a hiss on the first two seconds of the very first video clip, but does not have an issue with any of the subsequent clips.   So just put your dialogue track on A1, make sure there are no gaps between the files, and hopefully it should work.  I'm testing it now, and so far, it seems to help

      I found a partial solution, it helps to avoid the two seconds bug if you want to apply noise reduction to multiple clips, in cases such as interviews etc: Unlink the audio from the video and nest it, then apply the effect on the nested sequence. Using this method will contain the bug to only the beginning of your main sequence.

      I have the same problem with the delay with Adaptive Noise removal, I'm running Windows 10 and I was told by someone in Adobe that the delay is because I don't have a soundcard in my relatively new computer.  I doubt that somewhat. I was told I don't need a soundcard by the computer sales person when i bought this computer,  Do people in this thread who have the problem with Adaptive noise removal delay as well, have soundcards or not ?

      I don't have any sort of special computer, and I run Premiere Pro just fine. Sure, a better CPU, GPU, and soundcard will render faster, look smoother, and sound better while you're working on your project, but I don't think the computed end result will be any different.


      Hi there,

      You are right indeed if you have no deadlines and are completely okay with the speed of your workflow.  However, over the years for me I have found that the need for a fast computer is important because it is all about workflow for me as my clients have deadlines for me to meet and I also have my own deadlines for my own projects to meet.  I do video editing, photo work, 3D work, CGI, and VFX and have began to do it all in 4K.  I can say this with great certainty for me is that my workflow has greatly increased from my A computer to my B computer.  And already I cannot wait to purchase my A tower with the latest tech to take my workflow to the next level and leave both my laptops as back up computers when my A tower is doing something super taxing.  For me, I need a fast computer but for you, your needs may be completely different from mine, hence, why you are okay with what you have. 

      But in regards to the problem we are all complaining about, it is definitely an Adobe issue because I still have that problem and so do many of us.  My hope is that it will be fixed with an update.

      I'm struggling so hard with this right now. I'm editing an interview that had some background noise and adaptive noise reduction works great until I have to make some cuts. Now I've got the background noise jumping up high at the beginning of every cut. It's really jarring. The workarounds sound great for single clips, but what are you supposed to do when you are making many cuts in one clip?

      There isn't much that can be done but more work with a few seconds ahead of the video clip.  Unless CC 2018 solved the problem, that is the only solution. Even Audition doesn't have a solution. Now, the best solution I have found since having posted my last post about it being a workflow killer was to edit it all to the final product then rendered/exported all the audio and took all the audio to Pro Tools where I was able to get exactly what I wanted. Softwares designed for music is the solution. Even as I thought Audition was designed for that, it isn't. It still lacks some pro qualities that softwares like Pro Tools are built for. There are free music softwares out there that you may find more helpful for voice over or voices in clips.

      This is ridiculous and I am trying to edit a voicer over and the few seconds are throwing out the sequence.  Is there not another solution?

          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.
