Does nobody know or can't you be bothered helping?

Hi

I just need to know how to handle Vdub concerning the problem mentioned below. I'm sure its not difficult to do and would really, really, REALLY appreciate a teany bit of help. After all I am a woman and don't know much!!


I know another boring audio sync problem but would appreciate some help

Can someone please tell me how I go about decompressing audio stream to uncompressed wav file and then recompressing with a constant bitrate enoder?
I'm getting the usual VBR warning causing 3318 ms of audio skew.
If you could give me info on a guide or a quick explanation would be even better
I've already converted the video using Tempgenc, however if i can just fix the audio to match I'd be able to author and burn
Thanks

Under the Audio menu select "Full Processing Mode". Under the File menu select "Save WAV". Wait a few minutes while it runs.

If you're making VCD/SVCD and already have the video encoded you just need to make sure the audio is 44.1kHz, encode it to MP2, and multiplex it with your video stream. In the future you can just use the wav file as the audio source in tmpgenc.

Whenever audio is giving me trouble I extract it as a WAV file using VirtualDub (e.g. 'audio.wav'), then create a batch file ('audio.bat') with the 'BeSweet' command line shown below and then run the BAT file to create a clean 'MP2' file with the required conversions. I then merge this with the video file using the TMPGenc 'MPEG Tools'.

BAT file command:

"E:\Program Files\BeSweet\BeSweet.exe" -core( -input d:\audio.wav -output d:\audio.mp2 -logfile d:\audio.log ) -ota( -g max ) -ssrc( --rate 44100 ) -2lame( -e -b 224 -m s )

The '44100' is the output frequency you want and the '224' is the output bit rate (you can change these to anything you need).

This seems to cleanup most audio problems, however if it's a frame rate conversion problem (e.g. from a 30fps capture to a 29.97fps encode) I use Avisynth scripts to frameserve with video/audio framerate conversion with forced audio sync enabled).
