Donald Duck does all the voices in my mpeg2?

[reboot]

Just converted an avi into mpeg2 (SVCD) four different ways.
About the avi: 246 meg, 50min 40 sec, DivX3, 14.98fps, 352x240 (1.47:1).
First, using DVD2SVCD in AVI2SVCD mode, with Canopus. Video plays normal speed, but everyone is using helium to talk and it took just over 2 hours, plus the time to extract the video from the .bin file.
Second, using DVD2SVCD again, with TMPGEnc. Video plays normal, helium voices again, poor quality. over 2 hours again.
Same avi, converted in TMPGEnc. 1 hour 47 minutes, no playback problems.
Same avi, converted in Mainconcept. 37 minutes, better quality than TMPGEnc, although the filesize is a little large, which I can cut down with a smaller bitrate to fit on CDR.

Anyone have some insight as to why Canopus, and/or DVD2SVCD would screw up the voices like that?

[au7usa]

The bitrate of the audio on your DIV3 file was obvoiusly pretty low. What you describe sounds like the result of an inaccurate sample rate conversion.

Have you tried Shibata Sample Rate Converter (SSRC.exe) before?
It's free command line app, and i know there is GUI around for it somewhere.

There is also a setting in TMPGEnc to use it as an external tool. I've had good results with it, and even figured out a way to include SSRC_HP.exe (SSRC Hi-Precision) as an alternate choice.

[reboot]

Thanks, I'll look into Shibata Sample Rate Converter.
I was thinking there's got to be a setting somewhere in DVD2SVCD that I missed...maybe it's not sending the right data to Canopus, or TMPGEnc...might take some script editing, or some other equally confusing process.
It just irks me that almost $700 later, Canopus didn't do the job properly, although it's probably not Canopus, but DVD2SVCD that didn't script properly.

Check to see if your audio is mono,if it is then it will get screwed up like that using dvd2svcd,If thats the case then use a sound editor or virtualdub to make it stereo.

[reboot]

It's stereo. VDub and GSpot both report the same things.
I think it's the original is only 14.98fps. When demuxed then converted to NTSC SVCD 29.97fps then remuxed, the audio runs at (approx) double rate.

[FOO]

You will probably be sued by Disney and the MPAA for infringing on
a copyrighted duck voice.

[reboot]

And the estate of Mel Blanc et al, because of the Chipmunks sound too

[dafreak]

try loading the avi in virtualdub.
-click on streams
-click on stream list
-right click on the stream you want and choose convert.
-convert sample rate to 44100 for vcd or whatever you need.
-save the file as wav
-convert the wave file to whatever you need, using ffmpegGUI
-mux the video and audio.


this method hasn't failed me when i'm converting avi's to dvd compliant files.

[lordsmurf]

Convert sample rate WITHOUT resample in SOUNDFORGE or other audio software.

[au7usa]

I agree, sample rate should be calculated, not resampled in a way that misses some of the data.

SSRC.exe

[dafreak]

lordsmurf, can you please explain why?

[au7usa]

If were talking about the same thing, LordSmurf is saying to that a 32.00kHz compressed audio file should be decompressed to 32.00kHz wave and then the sameple rate changed with a competent app.

If you record a recording (Resample) you should expect some degredation. If you record a recording at a different sample rate, your really asking for it. The resample will disreguard any data that doesn't fit its expectation. Important info will be lost.

I like to use CoolEdit "Extract Audio from Video", so i can do sample rate conversion afterward.

[reboot]

Thanks for the tips guys, but I want to know why TMPGEnc can handle it, Mainconcept can handle it, yet DVD2SVCD with Canopus cannot.
If I use only Canopus, and select the proper settings, it too works fine.
The only breakdown is when using DVD2SVCD (in AVI2SVCD mode).
The only audio option that DVD2SVCD offers is "downsample 48khz ->44.1khz" tickbox, other than bitrate, and "Autodetect Azid Gain", whatever THAT is.

[FOO]

The resample will disreguard any data that doesn't fit its expectation. Important info will be lost.

Bullshit detected !

[RabidDog]

You were onto a loser starightaway with a file that plays at 14.98fps .. what the heck what was that?? half speed video with std sound or normal speed video with hi pitched sound. Its completely ducked, mate.

[reboot]

Yeah, I know it's a Bullshirt file Some lamer decided that was a cool way to shrink a DVD rip for quick download. The avi plays normal though, which is unreal. Not even jerky as one would expect. Once converted to VCD, it's not even that bad to watch on TV through my standalone.

[au7usa]

OK fine, hows this.

If you throw 10 pounds of shit up in the air and hold out a 5 pound container, your gonna miss some of it!

[au7usa]

I feel i should apologize for my language.

I almost never use words like "disreguard", or "expectation", and dammit i'm sorry.

[reboot]

LOL, excellent analogy, thanks

[RabidDog]

Am I meant to disregard disreguard?

[lordsmurf]

Changing sample rate without a resample makes the audio sounds like chipmunks or drunks in slow-mo.

You did that it seems.

To fix the mess you made, change it back (again, without resample).

TMPGEnc has troubles with resample on some files sometimes.

SoundForge is the only tool I'd recommend for what you want.
