Squeaking noises on SVCD images created with DVD2SVCD/TMPGenc 2.59

[rustywater]

Hi All,

Every image I create from a DVD or from a previously created AVI file has loud "squeaking" or "chipmunk like" noises. Worse during scenes with loud effects or music. Tolerable in voice only scenes. I just can't seem to get rid of it.

I've tried various audio bitrates from 160-256, tried downsampling from 48->44.1khz, tried stereo and mpeg51. I can hear the noises when I play the movie back on my PC and if I cut it to CD I can hear the noises on several different DVD players I've tried - on a couple of images the voice is almost completly inaudible ('scuse the pun).

My DVD player is a Pioneer S633A, but I've tried Phillips and Conia brands just to name a couple.

I've used DVD2SVCD 1.09 bundle three, and upgraded to DVD2SVCD 1.1 bundle 1c. I was originally using TMPGenc 2.55, but I'm now on 2.59.

I normally use 4:3 no borders, biLinearResize, and I'm in Australia so the DVDs are region 4 PAL.

I've seen on some posts where people have asked for ini files and log files to be posted. I haven't included these here in case it was not good manners to do so on one's first post.

The PC itself is an Intel 1.4ghz with 512mb RAM and 50g HD, 128mb nVidia 3 GPU, and a Sound Blaster Audigy (though the movies sound the same on SBlaster Live's and sBlaster AWE64's).

I often cut the movies over two days - the first to rip the VOBs and the second to do the rest. Quite often I'll take three days as the process takes quite some time on my machine, so I'll stop processing and pick up where I left off the next night.

Can anyone enlighten me as to why I'm getting so much noise, and how I can get rid of it?

TIA
Steve

Hi, let me give you a couple helpful pointers to help narrow down your problem.

First, have you tried doing the SVCD encode manually to see where your problem lies?

A couple steps:

First, rip your DVD to your hard drive (if it is not already there from DVD2SVCD), and run DVD2AVI manually, open the first .vob file from your DVD rip (normally vts_01_1.vob), remove the force film menu from the drop down (confusing there, it's in the Video Menu, under Field Operation. Make sure Force Film is NOT checked). Also, check that Audio Demuxing is checked (Audio menu, Dolby Digital, Demux all tracks).

Press F5, watch a few minutes in the preview window, and make note of what DVD2AVI tells you in the statistics window (Under Aspect Ratio, Video Type and Frame Type) *

After you have seen a few minutes of your film, and have these written down, then press F4, and save your project file somewhere easily accessible.

Now, run DVD2SVCD with your ripped .ifo file (that DVD2SVCD should have already ripped) and under the DVD2AVI tab, make sure NTSC Field Operation is set to OFF. Also, under the Frameserver tab, under Edit the Avisynth Script File, check Edit when DVD2AVI is done.

Now, make DVD2SVCD start your encode, and in a few minutes, it will come up with a text file with some stuff you can edit. Copy that text file to the same directory as your DVD2AVI project file, under any filename with the .avs extension.

Ok, edit that file and instead of the mpeg2source("") pointing where it is, change that to your originally make DVD2AVI project file.

Now, download this besweet GUI (http://dspguru.notrace.dk/BeSweetGUI0.6b61.zip) and put it in your DVD2SVCD/BeSweet directory after unzipping.

Run the file, and look at the top left.

Under BeSweet.exe, check the folder button, and find the BeSweet exe file, double click it, then hit ok.

Now, under Input, find the .ac3 file in the same directory as your DVD2AVI project file, that corresponds to the audio track you want added to your film (you should be able to play those .ac3 files in any windows DVD playing program, and certain programs that come with creative sound cards).

Now, Under Azid on the left about half way down, select AC3 decoder, to the right of that, select SSRC downcovert, and further to the right, in the drop down menu, select MP2 to convert to.

Now hit the AC3 to MP2 button that's green in the bottom right, and let it work.

If this file encodes and you hear no hissing or noise, then the problem lies in how the file is being encoded or muxed later.

Attempt this and if this isn't your culprit, we'll work on how to manually encode and mux :)

EDIT:

The * after DVD2AVI... I told you to remove force film, as I asked you to run DVD2AVI first, just to get a demuxed audio track to test manually encoding. The properties I asked you to write down will eventually be used to tell you what to do with DVD2AVI, or what parameters to use when encoding.

Also just noticed you're encoding PAL movies, so that would have to be unchecked anyway :)

@ArdenDag--> Well put together! Compliments on clarity of content and the amount of time you spent on this. You rock!

Hey rustywater-

Gee, now you have us feeling all guilty for not responding earlier (I'm referring to the other thread). But I have never seen this problem and don't know how to solve it, but I think I can narrow it down.

Before starting over, try this. Do you still have the MPG files of the muxed movie on the hard drive (don't allow DVD2SVCD to delete intermediate files)? If so, play them. How do they sound? If OK, then I'd say it's an authoring problem which can be solved without doing the whole thing over again.

If not OK, then do you still have the unmuxed .MP2 audio file in the movie folder? If so, then play it. How does it sound. If OK, then I'd say it's some kind of a muxing problem which can be solved. If not OK, then play the original ripped AC3 track. How does it sound? If OK, then it's a conversion problem. If not OK, then it's a hardware or ripping problem.

If you can't play the MPG file, then you'll need the Elecard MPEG2 Filter (http://www.doom9.org/Soft21/Filters/MPGDec.zip). If you can't play the AC3, then you need the AC3 Filter (http://www.doom9.org/Soft21/Filters/ac3filter_0_63b.exe).

I have had the same Chipmunks in my audio when I read your post.

What I did was the following (which bring me to my problem later);

I just loaded 'SVCD-settings; from the MISC-tab and selected 'STEREO' in the AUDIO-tab.


Before I tried to use the 5.1 setting and this is what gave me the squeaking noises also I started it from the installation right away (not knowing things should have been properly adjusted) before encoding.

I've been ripping for quite some time now and switched from VCD to SVCD but I'm still struggling with the AUDIO part in DVD2SVCD. Although the STEREO sound is from good quality and the VIDEO is of superb quality when I match it with previous VCD's I made (started using CCE recently which has much better quality then TMPGENC and looks pretty much like genuine DVD video). I'm still looking for a batch solution for 5.1 sound (or actually like I had it on the VCD AC3 sound which contained DOLBYSURROUND or DOLBY PRO LOGIC I'm not sure, but it was environmental audio... :-).

Hope any of you people can help me with this.

Many thanks in advance.

By the way, I hope your audio problem will be gone....

P.S.

I've been searching this forums and many others for over two weeks and I believe it could be possible with Besweet GUI, but when I start it all the technical terms you guys use do not ring a bell at my door.

I've discovered the SEARCH function of this forum...
.. and got my answer...

If I've appeared as a complete dumb-ass, well that's me also :)

Good-but you might tell rustywater what you did to fix it. Maybe he (and others) can use the advice also.

I'm just starting using DVD2SVCD.

At first installed DVD2SVCD and thought that was just it.

I rip my DVD with Smartripper.
All I did was change the dir's of the destination files.
I used TMPGENC in the beginning for encoding. I enabled 5.1 in the audio-tab. That's about it. Started to encode and with every try I got chipmunk-like sounds. Also the sound was not synchronised with the video.

I found that there were SVCD and VCD templates that can be loaded under the MIC tab (like in TMPGENC). And set my audio to stereo. The answer I found for the 5.1 problem was that it's not possible to encode 5.1 sound in MPEG2; or at least there's almost no standalone DVD player that is able to play it. Correct me if I'm wrong....

This should all be very simple to the more experiences users but from this time on my squeaking noises were gone.....

Hope this helps Manono...

I don't have so much time to experiment, so Í was simply looking for a batch solution in DVD2SVCD to get AC3 encoded surround sound...
