Help with reencoding

[YoYoZiNgZaNg]

I get this message when I open files with virtual dub that i have encoded with divx5 in Gordian Knot:

"virtualdub has detected an improper VBR encoding in the source AVI file and will rewrite the audio header with standard CBR values during processing for better compatibility. This may intrioduce up to 11,481ms(this number usually changes with each encode) of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder. (bitrate 128.0-+ 0.1 kbps)

I decompressed the audio stream to an uncompressed .wav file, which ended up being a little over 1GB, and then set VirtualDub's audio to wav source. I then set to full processing, and selected 128kbps MP3 for the compression. When I run preview everything is perfect, the audio is right on track, but after I start the actual encoding, it runs for a bit and then it stops. The clock keeps ticking, but frames per second goes down to 0, and that's it, I have to abort the dub to to anything. If I don't do it this way, then the audio track is all off, and screws up the whole video. Anyone know why Vdub is locking up like that??? Or even if there is a way to set up Gordian Knot to encode with a CBR... I have seen no option for CBR in GKnot.

Any help is appreciated, Thanks.

I don't know why vDub does that but why do you reencode? That warning message is just a message telling you that the audio is VBR, which normaly isn't a bad thing. Check out The vDub site (http://www.virtualdub.org/virtualdub_news_old.html) in this matter.
In any case, you shouldn't reencode the audio, if you want to do anything just use the original AC3 and encode this.

I have to reencode to add substation alpha script file, since gordian knot doesn't support substation alpha :( Maybe I should just take the time to learn all the processes myself and skip gordian knot alltogether.

Thanks for the above link to the vdub page.

Hi-

The whole idea doesn't sound too good to me. You know that you can just keep the SSA subs as they are and play them along side the video, right? So assuming you have some overriding reason for hard coding them into the video, then you also know that reencoding the video will result in degraded video quality, right? And you also know that by hard coding the subs into the video, the video quality will be even further degraded, right?

So, assuming that you still want to do this, first strip out the audio with the Save WAV command in Nandub and rename the extension as .mp3. Then Direct stream the video in Nandub without the audio. At that point you'll have a VBR MP3 soundtrack file and a video file with no audio. Reencode the video with the SSA subs, and when done mux the .mp3 back in with Nandub.

Thanks for the help.
