Problem adding audio effects (Denoiser) HELP!!!

[shanearama]

Hi everyone this is my first post.

I'm using Premiere elements 7.0 and shot a little movie using a sony bluetooth mic that was set to record in 5.1 center. Now I've got it and I'm trying to apply the denoiser audio effect but it will not let me. I can't drag and drop and the apply button doesn't illuminate green when I select it.

I've run it on other clips as well and these clips worked without incident but it doesn't want to let me do this one.

Anyone have a solution?

Thanks in advance

What do you mean by 5.1 Center? Do you really mean 5.1 channel sound? I am assuming that you meant 5.1 channel sound.

Were the other clips that worked with the Denoiser also 5.1 channel sound or were they Stereo (2 channel)?

Are the clips all AVCHD with 5.1 channel sound? If not, what are the video and audio formats of what worked and what did not work. What project preset did you set in the Setup at the Welcome Screen for this project?

Are you working in the Sceneline View or the Timeline View?

To be continued..........

With all my questions, I forgot to ask why are you using the Denoiser?

The video was shot in AVCHD format with 5.1ch CENTER. This is the video clip that doesn't allow me to use the denoiser. The reason I'm attempting to denoise is that despite the wireless mic the sound was low (another $200 bucks down the drain - thanks Sony:mad:). So I boosted the volume to make the audio more audible but in doing so also amplified all the background noise.

I'm new to premiere and 7.0 is my first try so in a book I bought (Muvipix.com guide) they mentioned that the denoiser could be used to get rid of ambient noise. I'm too inexperienced to know if there is a better way.:confused:

On previous clips I just used the built in mic on the camcorder so I assume it was a standard two channel audio. On those clips I pulled up old projects and atteempted the denoiser and it seemed to work fine.

I prefer right now as a nube to use the timeline view.

And finally... I am not sure what presets I used as I just clicked "New project" at the welcome screen and didn't pay any attention to the possible presets. But I can easily start a new project if that will amke things easier.

shanearama,

While I am thinking of an organized plan of attack on this issue, I need for you to try some things and report back:

1. Open a new project for this AVCHD with its 5.1 channel sound.

2. When you open this new project, you will be greeted by the Welcome Screen. Click on the tab that says "Change Settings". Then set as the default for this project the one that says AVCHD 5.1 channel sound.

3. Continue into the program Timeline.

4. Via Get Media bring your AVCHD with its 5.1 channel sound into the Media area and then drag it to the Timeline. What video and what audio track does your video and audio go to, video 4/audio 4 or other instead of video 1/audio 1??

5. Continue with your project and see if the same problems/concerns exist with the sound level and/or the use of Effects/Audio Effects/Denoiser.

There is a noise removal procedure using the free program Audacity that we can look into if need be.

Premiere Elements 7 and 5.1 channel audio can create problems for one another. But, let us see if we can find the answer to success together.

I changed the settings at project startup as you recommended and the video/audio were under video1/audio1 in the timeline. Attempted to apply the denoiser effect and still no dice.

This third party program Audacity is sounding more appealing. Is this something we can apply inside premiere or would I have to finish the project and export and then run that file through Audacity.

Check out BjR's thread here "Residual Audio from Camera"...go to the link in the thread for the YouTube Video on noise removal with Audacity.

That YouTube video was not produced by a person using Premiere Elements, so look toward the end of BjR's thread where I posted some suggested details relating to Audacity/Premiere Elements users.

http://www.elementsvillage.com/forums/showthread.php?t=42206&page=2

Basically, you are going to export ONLY the audio (as .aiff) from your video in Premiere Elements, import your audio as .aiff into Audacity, try to remove the noise in Audacity, export the noise removed audio from Audacity as .wav, and bring the .wav (noise removed) audio back into Premiere Elements to be reunited with its video.

Also read the rest of BjR's thread to follow the course of the issue presented there. It has not been updated with results lately, but it may give you some ideas.

The following is a link to the free Audacity download. Go for Audacity 1.2.6.

A nice little tutorial on removing noise from audio with Audacity

I must say though, removing ambient noise is not easy. That is why Hollywood uses sound stages and the director says 'Quiet on the set'. When doing live, on location shooting it is very important to have the right equipment ;)

shanearama,

I see that CE has contributed a noise removal tutorial link to your thread. I gave it a quick look over.

The major thing that I noticed is that the start audio file in Audacity was .wav. In the YouTube video link that I contributed the presenter says at the onset that the Audacity audio file for noise removal should be .aiff, but exported (after noise removal) as .wav.

I went hunting around for some general remarks about Audacity. I found that the program can use .wav and .aiff, but there was no "best format" cited that I could find.

When you get a chance, please let us know if you are making any progress in what you have as you plan for the future with improved equipment.

Good luck.

I have to say you were right. It isn't an easy task to remove the static. I ran the file through Audacity and it did help a bit. I imported back into Premiere and ran the denoiser function (this time it worked with the imported WAV file) and that helped a bit more.

Overall I think the audio is definately better but I would still charactrize it only as acceptable. I think its like photography - have it set up properly when you take the picture and you'l minimize post processing. Same thing here, a better set up or microphone equipment would ahve made a difference.

Overall though I think this has been a success. And I thank everyone for their advice and contributions. :)

Thanks for the feedback and congratulations on your success.

How did you know that "success" is one of my favorite replies.

Continued success.
