2 Aduio Streams

[rufus]

Hi,

I have a divX 5.0 video clip that I wish to convert into a mpeg2 ->DVD Video File to burn onto a DVD, with the following details in GSPOT:

“Video: Codec – 4CC – DX50/divx, Name – divX 5.0, Runtime – 1:35:48 (143,705fr) xy 576x240 Bitrate – 770 kb/s FPS 25.000 Qf 0.223 bits/pixel.

Audio: Codec- Name – 0x0055(MP3)ID’d as MPEG-1 Layer 3, Bitrate – 118 kb/s (59/ch, stereo) VBR fs 48000 Hz.

The filesize is 698 MB (715,674 kb). Of that roughly 534 MB (76%) is video data, the remaining 164MB (24%) is audio data.”

When the clip is played there are 2 separate languages spoken.

When I opened the video clip in AVI-MUX_GUI 1.16.4 I found that there were 2 separate audio streams 1 of 79.5MBs and 1 of 80.5MB.

The audio stream I wish to use to make a DVD Video File is the 1 of 80.5MB, which plays for 1:45:32. The divX 5.0 video clip when played lasts for 1:35:48.

How do I make the audio stream “fit” so that it doesn’t go out of sync? Do I need to use a “wave” audio stream to make a mpeg2 file and if so how do I extract/make that?

Many thanks for your help and attention.

"When the clip is played there are 2 separate languages spoken."

Are you hearing both languages simultaneously?

[rufus]

Yes, there are two separate languages spoken when played.

Yes, I hear both languages simultaneously.

"Yes, I hear both languages simultaneously."

Did you download the original Divx clip? If the file has both languages superimposed, then there is no way that you will be able to separate them. First, you could try and "De-multiplex" the audio from the video. Open the divx file in "VirtualDubMod". Go to "File" > "Open Video File". Then go to "Video" and select "Direct Stream Copy". Then go to "Streams/Streams List". The available audio stream(s) will be listed at the top under a category called "Desc". Click on "Demux" to save the stream(s) independently. If you find that both languages are still contained in the demuxed audio file, then you may be out of luck.

I have been able to separate the audio streams into the 2 different streams, ie 1 stream for each language, however when I put the audio and video stream into TMPGEnc and convert it, even using "Audio Gap Correction" feature in "Source Range", the audio is out of sync.

If you play the original Divx file, does it play in sync? Also, the following link could provide some useful information with regards to your issue:

maybe you could DISABLE the unwanted audiostream in virtualdubmod instead of demuxing audio

next save file to new name and keep your fingers crossed

The original divX file when played back is IN sync.

"The original divX file when played back is IN sync."

Try the approach suggested by "UncasMS".

I was able to disable the audio stream I didn't want with VirtualDubMod and it worked alright, however when I encoded it into mpeg2 with the video stream, it was out of sync when I played it back.

I then used VirtualDubmod to separate the 2 audio streams from the divX file. I then took the one I wanted and the video stream and put them into TMPGEnc 3.0XPress and encoded them to mpeg2. When I played the mpeg2 file back the audio and video streams were in sync, so I then made it into a DVD Video File with TMPGEnc DVD Author and then burned it onto DVD. It plays well in my standalone DVD player.

Thank you for your help and suggestions.
