no audio?

[carla]

hey everyone. um, i'm new to this video thing... today i tried to create a vcd for an avi file i have. i converted it using TMPGEnc and then split it (it was too big for the cdr) and then burned it onto the cdr. problem is, when i went to play it, it looks great, but it has no audio. looking back, i realised that the original .mpg file i got after the conversion didn't have any audio either (now i feel totally stupid for not checking before burning, but...). why is that? since i'm a newbie i used the wizard for conversion, and i don't know where i screwed up. could anybody please help me with this?

carla.

"but it has no audio. looking back, i realised that the original .mpg file i got after the conversion didn't have any audio either"

If you have the original AVI file, load it into VirtualDubMod (or any variant program of Virtual Dub). GO to "File" > "File Information" and post the information contained in both the video and audio sections of the dialog box.

ok, i tried loading it and it told me:

virtual dub has detected an improper vbr audio encoding in the source avi file and will rewrite the audio header with standard cbr values during processing for better compatibility. this may introduce up to 13165 ms of skew from the video stream. if this is unacceptable, decompress the *entire* audio stream to an uncompressed and recompress with a constant bitrate encoder. (bitrate: 134.2 +- 18.8 kbps)

since i didn't understand any of that, i clicked on ok... was that right?

file information was this:

video--

Your audio stream is mp3. In Virtual Dub, open your AVI file. Go to "Video" and select "Direct Stream Copy" and then go to "Audio" and select "Direct Stream Copy" also. Then go to "File" and "Save WAV" to convert the mp3 to a WAV file. Then, go back to TMPGENc, select the VCD wizard template, but this time load the "Demuxed" Wav file from Virtual Dub as your audio file and proceed with the encoding process. Or, you could “De-multiplex” the mpeg file that you encoded from your original AVI file and use the wav file as the audio source and “Mulitplex” it back with the .m2v file. Use the “Mpeg Tools” feature under “File” to accomplish those tasks.

that worked thanks a lot!
