High pitch noise in AVI to MPEG1 with TMPGEnc

[samyboy]

I have a old (VHS) movie I am converting from AVI to MPEG using TMPGEnc. It's DV captured using Adobe Premiere 6.0. I am using standard NTSC VCD template that's supplied with TMPGEnc. I always get a high pitch noise in my mpeg1 each time there is a male voice speaking ( with low(er) frequency audio ). Female voice(s) does not have this noise attached with them. I can not hear the same noise either in source video or AVI file. So it's the conversion that is generating this.

Buying another encoder is not a option for me right now.

I tried saving "audio only" AVI using Premiere. Used original AVI for video source and the new AVI for audio in TMPGEnc but no use. I still can hear the same noise.

Can you please suggest me any way to eliminate this audio noise ? I search this forum in case similar question is already answered but couldn't find one.

I think I know what the problem is, don't know how to fix it..

Problem is with audio freq. DV capture rate with premiere is 48KHz. Standard VCD conversion encodes it at 44KHz which generates this noise. If I force encode at 48KHz with the unlocked template there is no noise in the resulting MPEG1.

Tried using SCMPX and tooLame encoders as somebody in other post suggested, but no use. No matter what I do, noise appears when I encode at 44KHz freq.

I am personally out of ideas, I will have to resolt to non-std VCD encoded at 48KHz if I am not able to fix this.

Any ideas folks ?

use sound forge 5.0 or cool edit pro to try converting from 48khz to 44.1 khz....the results should be professional with those said programs

I have sound forge
think that will stop the snap crackle and popping on anime avi files I tried converting?

I have encountered the same problem, but it took me a while to figure out what went wrong because I never realized I had selected to convert the audio from 48khz to 44khz when encoding with TMPGENC. I had been making all of my other discs non-compliant by leaving them at 48khz. I just posted a message about this asking what is the likelihood of running into DVD players out there that can't handle 48khz.

I did have someone mention that dvd2avi does a decent job of 48->44khz conversion, and they also said that TMPGENC was notoriously bad at it. This explained a lot. TooLame was also recommended. Hope this helps.

yeah I tried too lame it works
but I'm looking for alternatives for audio other than tmpge
thats why I would like confirmation if sound forge does a great job

[low_iq_88]

for sound forge 5.0, you need an external plugin for pops and clicks removal (i believe i had to add it separately)- email me if you can't find the plug-in on your own...the results are quite good....goldwave and cool edit can do this process with no plug-ins....the results vary with each program, but if the pops/clicks are not drastic they all will do well

I actually made great progress last night
I stripped the audio out into a wav file
encoded it to 44.1 and I ended up with no messages with nero at all
audio played smoothly
Tried another movie this time a dvd
used dvd decrytper dvd2avi normilization at 72
did 48khz-44.1khz on medium
reencoded the wav file for the hell of it with sound forge
Then just loaded everything in tmpge 12j on high quality
burned with nero at 24x
again no error message with nero
vcd was completely compliant
played flawlessly on my pioneer 343
I definately suggest sound forge for all who may have this problem

Instead of using DVD2AVI's resampling (which is very slow) or using a separate application such as Soundforge, you could also try using a sample rate converter as an external tool in TMPGEnc. I use SSRC (http://www.geocities.co.jp/Technopolis/9674/ssrc/) which is free, reasonably fast and, most importantly, sounds great when resampling to 44.1kHz.

One thing to keep in mind is that you will need some additional harddisk space because TMPGEnc creates a temporary WAV-file when resampling, but that's about the only disadvantage.

yeah that one works as well I tried that one
but for some reason I just felt like putting sound forge to some use lol

[samyboy]

Thanks for all of you who replied-read the post.

Freshman, you suggestion seem to work well. I did re-sampling with SSRC and my test run gave good results. Very little noise this time. Thanks a lot for your help. You saved my first VHS->VCD conversion from being non-std at 48KHz.
