Premiere Pro exporting without DeNoiser audio effect..

[James Poll]

I had a similar experience with PPro CS6. In my case, the denoise effect would actually work on exported material, but it would only pop in a couple of seconds after every cut (so you would hear hiss at the cut point for a second or two, followed by a quick drop to the noise-reduced audio). It was really annoying, because the noise kept popping in and out during playback of the final movie file.

It seems to me that the denoiser requires some “read-ahead” time to make the necessary calculations, and apply the noise reduction. When you play the clip on the timeline, it has time to read ahead and apply the reduction before you hit a cut point, but on export, it doesn’t read ahead and only starts to process *at the cut point*, which means that you have to wait a second or two before you notice any noise reduction.

This is just a theory (which seems to fit the evidence)… I don’t know if this is what is actually happening or not, and I haven’t had time to go back and explore it some more.

Has anyone else had a similar experience, or been able to work around this? It’s pretty stupid, actually… the denoise effect isn’t half-bad, but if it doesn’t work on export, then the plugin is essentially useless (as is Premiere’s export function, since you can’t count on your final export being what you see/hear on your timeline).

Yes this is a major flaw and many people have experienced this. My workaround is to put all the audio clips with the same effects onto a single track, export that entire track from in to out with no effects, then import that file and apply the effects to it.

Another workaround is to add the effects not to the clip themselves, but to add them to an entire track on the audio track mixer.

Thanks guys.

Thanks for that work around but I need to edit the effect for individual clips. I chatted to Adobe support and they said they were aware of the issue but they hadn’t made a fix or work around yet….

I’ve ended up sending the clips to Audition and doing it again in there.

Would be good if Adobe’s effects actually worked though!!

I’m actually having the problem in Premiere and in Audition. I’m removing wind and it sounds great in Audition. It renders back into Premiere and sometimes the sound reduction works, sometimes it doesn’t. Sometimes it starts working mid-clip. Very frustrating as I’m pretty sure my client thinks I’m an idiot at this point…

The suck levels are through the roof with the Premier DeNoiser

I can understand the realtime playback being shonky, but surely the export render engine can apply some kind of buffer on the effects to give it time to kick in.

Hi Nathan,

I am actually having the exact same problem at the moment for my work with a client Just wondering did you find a way around this?

What happened to me was, I didn’t delete the denoiser filter before bringing the clip into Audition. Then I was editing my clips as a multitrack session. Usually I edit each clip individually and simply saving replaces the original clip in Premiere. When you edit using a multitack you actually have to export it to Adobe Premiere Pro.

So I was actually just listening to the faulty denoiser filter because I didn’t properly export from Audition.

Not sure if this is the answer you guys are looking for but I found a fairly simple work around. I use Audition for streaming ‘cleaned up’ mic audio for my youtube video game lets plays. I ran into this problem when I wanted to do a straight up record of my voice to then put it in After Effects but it wasn’t coming out like the live version. the hiss was still there.

So what I figured out was: I run my streaming software like OBS or Xsplit (capable of recording audio that goes to my speakers or headphones). I record the audio in audition, play it back (with the 5-10 grace for the effects to kick in) and then I record to HDD using my broadcasting software. It records the playback from audition flawlessly and then renders it out in like .mp4. Place the .mp4 in After Effects with that audio in it and turn off the video and voila

TL;DR >
There might be a faster/easier way to do it with other more simple audio recorder softwares that can record audio from your speakers/headphones. But to put it simply. Take your audio, place it or record it directly in audition, apply the desired effects, then play it back while recording it using another software (for me its Xsplit broadcaster or OBS)(both of them free OBS has higher quality audio capabilities.)

I see your post is dated August 2014 and here we are August of 2016 and this problem still persists in the Premiere Pro software. But good news!!! I figured out a workaround. Ok, so there are a few seconds that the Denoiser effect needs to be able to initiate so if you have cuts that are edited and you apply the effect to each one, you will still get the hiss for the first few seconds on each clip upon export. When you are editing it sounds fine but when you export you can hear the hiss. Not cool right?
So, what you do is apply the effect to the master clip before editing. Hopefully there is some lead time (at least 5 or 6 seconds) at the beginning of the clip before your audio starts. Export just the audio into a wav file to your media folder. Then import the wav to your project. When you play the clip it will have the hiss at the beginning but then it will stop after a few seconds and the rest of the clip will be hiss free as there is no effect on this clip. Then you can edit the clip into many sub-clips and there is no more problem. I just did this with a narration audio clip and it worked fine. I guess the only problem will be if you do this workaround on a video/audio clip, you will have to export both the audio and video and that will take longer. Otherwise you will have to separate the video and audio files and then sync them up again in the timeline after the workaround. Kinda sucks cuz it’s a lot more work and can get complicated with all the extra files but it works. i hope this helps you or anyone else reading this post.

If I’m understanding what you’re saying about allowing”read time” I at least figured out a solution that worked for me. Sometimes I have to increase audio which adds a lot of white noise, therefore having to use the Denoiser. But when I would add the plugin to small 2 second clips that I chopped up, the effect wouldn’t work… probably for lack of “read time”. But when I applied the Denoiser to the ENTIRE 7 minute clip, all the noise magically disappeared. This took me a while to figure out because I too was getting frustrated that in the timeline the clip sounded cleaned up, but when exported the fuzz and white noise was still there. This method worked for me and hopefully will relieve my future stress LOL. I hope this helps.
