Background noise?

[volcom_1]

Hi guys,
I need some help. My captured video has this very irritating background noise but I could still hear the actual clip. The images were perfect though. So could anyone help me?

Use Gold Wave. Load your video into it, select Effects-->Filter
-->Noise Reduction. Save.

Ive tried that but it does not work. The background noise is rather metallic and I dun seem to have that problem when I connect my camcoder to my tv set. Do you think it will help if I re-install my drivers for the capture card? N that noise level is increasing every time I try to capture the video....very irritating. Hope some kind soul cld help me with this....thanx a lot

How is your sound captured?

[celtiber2]

Is your camcorder configured for 32kHz audio? If so try changing this to 48kHz (which is the standard sampling rate for DVDs). If have a lot of material recorded in 32 kHz you will need to take care what program you use when re-sampling upto 48kHz. Getting this wrong will cause the sound to be very metallic.

I know exactly what your problems is and exactly how to fix it. First, you're talking about AUDIO background noise.
This results from the fact that you are capturing the audio at 48 Khz but TMPGEnc assumes the audio is a 44.1 khz stream. TMPGEnc produces a hideous form of metallic audio distortion when it tries to convert the 48 khz audio stream to 44.1 khz.
Here's the solution:
[1] Capture as normal with your camcorder off TV;
[2] Get into TMPGEnc and (THIS IS VERY IMPORTANT!) select NEW TEMPLATE. TMPGEnc will ask DO YOU WANT TO RESET TEMPLATE? Answer YES.
This zeroes out your template.
[3] Use BROWSE to open up the file you captured. If you DO NOT reset and elete your TMPGEnc template, it WILL NOT CORRECTLY SHOW YOUR AUDIO SAMPLING RATE. This is a serious known bug with TMPGEnc.
Your audio sampling rate will now show up as 48 khz, instead of the false report of 44.1 khz you would have gotten if you had stuck with the preset TMPGEnc VCD template.
[4] Now select FILE > SAVE AS > .WAV FILE.
This will create a separate 48 khz .WAV file containing your audio.
[5] Run an audio editing program on the 48 khz .WAV file to resample it to 44.1 khz. I use sound forge XP (since it came with my audio card), but there are many freeware audio editors out there -- CoolEdit 2000 demo is an excellent choice.
Resample to 44.1 khz nad save as the same filename.
[6] Now exit TMPGEnc and this time chosoe the standard VCD template. But when you chosoe BROWSE choose the capture file for your video source, but this time choose the audio file you resampled as the audio file source. (You are now choosing different separate audio and video files to encode the video and audio protions of your VCD).
Voila. Problem solved.
Your audio will now sound perfectamundo on the resulting VCD.
HINT: Before you resample the audio, choose NORMALIZE. This will make the audio as loud as it can possibly be without clipping and will eliminate the "low volume" that sometimes plagues the audio portion of VCDs.

Where is the new template option? I cannot find it.
