Hi guys, Im having a problem with the audio on a DVD2svcd conversion.
The source dvd is a region all the quality is off an svcd nature, ie i highly suspect the film
was a high quality telesync which has been recompiled into a dvd-compliant structure.
The sound is of reasonable quality, albeit a little echoey and distant on the original.
The problem with the finished svcd is that it sounds like everything is under water, almost like playing a 45rpm record at
33rpm, Now would it be the audio downsample which caused this?
Is it possible to alter the besweet settings or can i do the audio extraction and encoding outside of the main program.


Oh while we're on the subject normally i use 99min cdrs and aim for a 975mb size i seem unable to use 224kps as the program will warn that im over the specified bitrate limit 27XXkps.Any ideas as
i notice that besweet reports 192kps as an illegal audio bitrate and may be the cause of my cce crashes. However i must say the latest release 1.08.1 is the most stable yet with cce2.50.

Firstly the audio logfile

i would suspect :D:\Program Files\DVD2SVCD\BeSweet\BeSweet.exe -core( -input D:\Program Files\DVD2SVCD\Movie\Extracted_audio_1.ac3 -output D:\PROGRA~1\DVD2SVCD\Movie\Encoded_audio_1.mp2 -logfile D:\PROGRA~1\DVD2SVCD\Movie\Encoded_audio_1.log ) -azid( -L -3db -c normal -g max ) -ota( -d -33 -r 1200 1001 ) -ssrc( --rate 44100 ) -2lame( -e -b 192 -m s ) i've read the logfile and didn't find the place where BeSweet says 192kb isn't legal.

You are getting that error when you use 224 because when you add your Max video bitrate to your audio bitrate of 224 you are above the 2756 warning level. You have a couple of choices on this.

1. Reduce your audio or video bitrate so the sum of all your parts is below 2756.
2. Uncheck the warning on the bitrate tab, make sure your player can handle the higher bitrate.

In my case my player can play way over the SVCD standard rate so I uncheck it and change my bitrates where I want them. I spent a few days testing with single chapters, CDRW discs and CBR encoding so I am sure I am always at a specific bitrate. To get an idea what your player can handle check out the DVD player list at www.vcdhelp.com.

I am sorry, but I can't help on the audio problem you are having.

ive noe reproduced the exact same fault on a 5 pass encode of a ntsc dvd.:devil:
Its almost as if the picture are being converted to pal but the audio is staying at 29fps?
Ive decided im going to leave them as ntsc as they are fine in that format. Is it a bug in the 0.8 build?
