Part of audio just vanishes after cutting XviD

[legionpc]

I have 1 XviD file that required to be cut in half before it would fit on onto a CD as SVCD. This file also has VBR MP3 audio. So, what I did, was open it in vdub, at the beginning of the file hit set selection start, then I jumped to the frame I wanted to end the part on, which was the frame directly before a keyframe, and selected set selection end. I opened the audio menu, chose full processing mode, and under compression selected uncompressed. Then I went file > save wav, and the wav for the first half saved. Did the same thing for video, except used direct stream copy, and selected 'no audio' under the audio menu.

In TMPGEnc I selected the uncompressed wav as the audio source, and the cut avi as the video source. Encoded to NTSCFilm SVCD, worked perfectly, file is in sync. Heres the problem:

For the second half I did the exact same thing, except I started the cut on the keyframe after the final frame of part 1. Video saves fine, but the first 11544ms of the audio stream is missing. The audio is 46:18.096 long, and the video is 46:29.640 long. Using Sound Forge to stretch the audio made no difference at all. It was still out of sync. Introducing a 11544ms delay to the audio in vdub however, DID work, except for the first 11.5 seconds of the file, there is no audio, after that its in sync.

Why did that 11.5 seconds of the audio not save when I extracted it in vdub? More importantly, how can I make it save?

EDIT: Important to note, on the original uncut file the audio is exactly the same length as the video.

Thanks

You can also try to encode the full movie to mpg and then split the whole mpg into 2 parts.

I was tempted to try that, but add this to the equation:

It took me 28 hours give or take for each half of this video file to encode. So to redo it would have taken me over 2 days. I wasn't about to try that unless I had to (266mhz pentium 2, using 2-pass VBR)

I have solved the problem though, I think. I extracted the audio in virtualdub for the entire file (not just the second part) then cut it in goldwave. The missing 11 seconds is now back

Thats´s great that it worked for you,if you want to encode it twice as fast,then choose CBR instead of VBR but the picture is said to be not so good as VBR but for me I haven´t notice big difference.
