Yes, I can hear the air conditioner no matter what I do. It seems like nothing has changed.

I am using the demo version and have 6 days left. If I can get this thing to work I will buy it right away.

I tried using Cool Edit with some success, but you have to strip out the wav file from the video and then put it back, which is killing me in render time since these are very long mpgs. That's why I'm hoping the SF noise reduction plug-in will work.

Thanks, I'm going to try that.

Are you overlooking the more basic step?

I don't use SoFo's noise reduction, but every other similar application requires you select a section of SILENCE, then the noise filter is applied. In other words the first step is to find a second or two on your video where you ONLY hear the hum. Then those frequencies and ONLY those can be masked.

Remember not to try to get rid of ALL the noise or that likely will flatten the wave form for what you want to keep. Usually blocking between 50-70% of the offending noise is all you need to do.

noise print
you must take a noise print
then run a pass
you will have better luck removing an air conditioner with two passes rather than one giant pass
good luck

Yes, I was going to say that but figured he was doing it---when Billy Boy says silence he means that you must select about five seconds of time that has no dialogue music et al. but does have the sound of the air conditioning--

I did that. I selected the hum with the Noiseprint on, played the segment, stopped. Then played it again and the hum is still there. Tried adjusting the sliders to max, played again. No difference.

Maybe I'm choosing too small a segment? It's 30 seconds. Also, it may not be an air conditioner. Sounds like an electronic hum.

Try using less than 12 seconds. I don't know why, but I seem to remember reading that from DSE. Maybe I'm confusing something. But I recall him mentioning something about not going over 12 seconds for a sample. Maybe it was acoustic mirror though.

anyway, worth a try.

Can you post it to a web site?

The process is generally like this. Remember I use a different application.

1. open the file.
2. select a section with noise only (silence)
3. make a noise print
4. SAVE the noise print to a file.
5. reopen the file, apply the noise print to the file you're fixing
6. save

I wrote a tutorial awhile back over at Kelly's site. You even get to see my ugly mug and see that I got to go on a diet. <wink>

But that's with Cool Edit. I know how to do that. My question is how do you do that in VV3 with the noise reduction plug-in? Is there a way to apply a voice print done in another application to VV3?

The reason I want to do this directly in VV3 is because I have a few hour-long mpg1 videos that were terribly recorded originally and contain a bad hum. To separate the audio track and import it into CoolEdit, and render that... AND bring it back into VV3 ...AND render that... would take forever.

I just can't figure out why the plug-in is not working. Maybe there's something wrong with my installation or system because the other audio VV audio plug-ins don't seem to work either. For example, I applied Reverb to the extreme and nothing happened.

1. Select a noise sample. Smaller is better, or it's too much information. Try 100 ms or less
2. Make a noise print/save
3. Now apply that noise print against the audio

Are you trying to do this as a realtime plugin, or are you using non-realtime FX? Noise reduction CAN'T work in realtime, because of the nature of the plug. It's very, very processor intensive, so you'll want to do this as a non-realtime plug. Especially if you are editing MPEG, which already brings the application halfway to it's knees.
I've never tried editing audio from an MPEG 2 file, but it's gotta be painful to the processor.
That said, if you have Forge 6.0, this is MUCH faster and easier. It just becomes another take in Vegas.

Read the instructions. It's not intuitive at all the way it's set up in the SoFo plugin. However, the help file does take you through it step by step, and it does work. I did it once. I don't remember the exact steps, but it is more straightforward in Cool Edit. As far as sound quality goes, I don't know which is better.

You might try the paragraphic equalizer and set it to 60, then bring it up from there to 120 or more. I once edited a movie in Premiere that had an annoying hum from the microphone used at the event. I tried 60, then for the heck of it, 120, and it worked. (Anything's worth a try!).
