AVI to VCD conversion doubling size of original AVI?

According to the steps on VCDhelp guides they recommend Using DivFIX first then VirtualDUb to extract the audio. I was assuming by extracting the audio it was removing it from the original avi or DivX. So is essence we extract the WAV and then with TMPGEnc we merge the original AVI with the extracted WAV? Doing this takes a 50mb clip into 100+ mb territory pre VCD burning stage. Is this normal? When I merge the audio and video is it possible to merge the audio as a 128KB/s bit-rate MP3 to cut down on some of the file size? Help as I am at a road block here and don't want to continue till I get clearer answers. Thanks

 

You should be able to open the AVI as the Video and Audio Source in TMPGEnc. I have done this, and it seems to work fine when converting to MPG. (Make sure that in environment options [tools menu], file priorities aren't lower than 0)

 

I am able to open the AVI just fine using TMPGEnc.

What about my original question was misunderstood? I was asking why the file size doubled and if there was a way to get a AVI minus the audio (which would appear less than the original AVI) so then later I can merge a MP3 audio file, (also smaller than the extracted WAV file) back with the original video portion of the AVI. Capeshe?

 

When loading it into TMPGEnc, only load the AVI as the Video Source. Use a program to convert the AVI Audio to MP3 (just search for one on the net), and load the MP3 as the Audio Source.
No matter what you do, the file size is gonna be larger cause you'll have to decompress the AVI Audio to compress it to MP3. Hope this helps.
P.S. I would just convert it with the original audio, as TMPGEnc will default the audio to 224kbps anyway
