Denoiser problem

[FamilyLegacyVideo]

Hi,

I've applied the denoiser effect to a number of clips to eliminate some hiss from an interview. (Need to match audio quality from a interview shot on an EX3 and then continued on a DSLR.) Seemed to do the job just fine until I played back the timeline. There is a lag in the effect as I go from clip to clip. Some of the audio levels start really low and then come up to normal, as if there's a delay on the effect. I've seen some old posts reporting this problem and am wondering if any of you can tell me if there's been any progress on a fix for this denoiser bug. Using Premiere Pro CS5 on a Windows 7 machine. Thanks.

I'm having the exact same problem. Can anyone help?

I've had this problem and I had to clear my cache to get it to stop.

Thanks for the reply. I found how to clean the cache but not clear it. Is there a difference? If so how do I clear it?

There is no difference between them. If you clean it that is the same as clearing I just used the wrong word sorry.

Not a problem. Thanks again. I cleaned, but the problem still happened when I re-exported. Do I need to redo the denoiser after cleaning?

[josephs51576386]

I dunno then, the only other thing I can think to try  but I doubt will work is to maybe apply the denioser to a audio track and put that audio on a track all by itself that needs the denioser to be used on it. Then try exporting it, maybe if you use the audio track to apply it rather than putting it on the clip itself it will be normal. For me cleaning the cache fixed the issue so I don't have any other suggestions other than trying the track method... Sorry

I have not used the audio denoiser in CS6 only 5.5 as you are using, but on Mac. It was horrible buggy and was crashing our system. We found other posts (I think Mac and PC) that were similar, so we deleted them and looked into Audition initially (it does a super job) but to speed our workflow we settled on using the EQ filter in Premiere. Took quite a bit of tweaking to get it right, but end result was good. I submitted a bug report to Adobe.

I have the same problem to I can freeze the noise floor (at the highest point) and get no delay in the timeline but the end result when exporting never works correctly. This is one of the many problems adobe needs to fix.( They really need to fix the buggy cuda engine it suck! “Crash city on 3 PC’s) Anyway….    What I do now is keep all my voices on a single track and not worry about the noise. Wait for the client to approve the video and export it to Audition.

Strange, everyone I work with uses the denoiser and nobody has ever had a crash because of it. Guess it really goes to show it depends on the system itself.

Hey Guys,

I have been having an audio export problem. I am shooting on a Panasonic GH5 at 29.376 fps with an external tascam 70d audio recorder.

As I edit my interviews for my client I am able to playback the audio in premiere pro, but when i export my file and try to post on Fb or IG I am left with this hissss sound all the way through instead of the talking head audio. Can someone please advise on this situation, this has been giving me hell for a week and half now. =|

I have tried multiple sequence settings as well as export settings, as well as running it through the media encoder. Things like this sometimes makes me want to switch back to final cut pro =(.

Are there any specific settings that you use that you think i should try.

I believe it has to do with audio level keyframes. At least when messed around with them it confused the DeNoiser filter. After deleting the keyframes or putting them on similar levels DeNoiser worked.

SOLUTION

If the noisy clips are the only thing on that audio track, you can add the Denoiser effect from the audio mixer panel rather that applying it to each clip. The effect will apply to everything on that audio track, and I've found that it gets rid of the delays and oscillations of the Denoiser effect lots of times.

Open the audio mixer panel and you should see a slider there for each track and a master. At the top left of the mixer panel UI is a triangle toggle like the ones on all of the bins in Premiere's UI. Use the toggle to expand the mixer panel to show the fx bus. There you can pull down a list of all of the audio fx to apply to each track. After adding an effect to a track, right click on it and choose "edit" to make adjustments. You can do this while your timeline is playing to hear the results. You can also keyframe effects on the timeline by setting the track display to "show track keyframes". That option is down on the audio tracks in the timeline panel.

Since I learned of these options, I know find them indispensable and you them on nearly every project

This it the Trick!!!  what a weird deal.

I do think this BUG shoud be fixed..if it is. For me- when I added the denoiser to a clip and tweaked it to my liking, it works on the rendered video.  But when I export the sequence: each clip with the added denoiser effect starts off with no sound fix(hissing) and then it kicks in after about a sec or 2 and sounds clean.

Filters make things easy. But I'm always gun-shy with auto "fixit" filters. We have not tested the audio denoiser filter in CS6, but I don't find the need too. In our small staff setup we try to find something fast, but not cut too many corners. We ended up creating two EQ presets for interviews with preamp hiss. If those don't work then we send the soundbites to Audition to remove the noise there. That's been a good workflow for us.

Abrapiro - This was almost a perfect solution. Thanks. It worked well for my entire segment except for the very first clip. True to denoiser's form, when the clip started the audio dipped and then jumped up - but was good for the rest of the program. Luckily, I had that piece of sound as an MP3 file, which didn't need noise reduction. I put that on another track and then transitioned to the other, "denoised" track when normal levels resumed there. I still find denoiser very buggy and plan to avoid it in the future.

Hey abrapiro14

This is by far the best tip I have seen on cleaning audio in Premiere Pro. I am working on a short film that was had thedialogue recorded with the same mic, same room, same day meaning the noiseis consistent, you just saved me copying and pasting the deNoiser on a multitude of clips not to mention that fact that Premiere kept crashing. I was just about to call Adobe to give them an earful when I stumbled on your solution to deNoiser a track rather than individual clips. The additional benefit is that Premiere has stopped crashing so you killed two bids with one stone for me (no anmals were harmed in the process).

Thanks for sharing, people like you make the fimaking world a fun place.

Awesome thanks!

[yuanchenliu]

Saved me big time!

Thank you so much for the tip. Works perfectly.

Hi Abrapiro,

I tried your solution and it doesn't work for me. I added DeNoiser from the Audio track Mixer, adjusted reduction to -15. I also cleared the media cache and I still get the 2 second delay. Please help. Thanks!

[Redhatgeorge]

‌I am having this issue also. I want to try your solution but I am using Premiere Pro CC and I just can't seem to find where I can apply the audio effect to the whole track instead of each individual clip.

Click on Window > Audio Mixer. The panel will appear in the top-left portion of the screen. Within that mixer panel, click the dropdown arrow in the top-left corner to see the mixer effects menu.

I recently switched from FCPX to Premiere Pro because of my workplace requirements, and discovered this denoiser issue - I tried applying to the master track as suggested in the answer, but the denoiser still fails to apply to the first portion of the video.

As I film interviews and there are things like A/C noise and hum that must be removed, this is a big issue for me - does anyone know a workaround that applies the denoiser from the very beginning?

I do not have Audition and am not in a situation to get it just for fixing audio in my videos, so I need some solution that only uses Premiere (or some other free plugin/software) =/

[Ted Abundant]

With a little extra work this worked for me too! Best to just have great audio at the start. I will need to invest in some lav mics so I dont have to do so much post work. Thanks

Hi, you are genius!! you've solved my problem which took me days to find the answer!! Thank you so much, very much appreciated. Muack Muack!! 
How to give you a like?!
