    Losing sound as well

    Hi, I've been having a problem trying to convert avi file to mpeg so it can be played on vcd/dvd player... I've read a few threads in this forum (though I really don't know most of the terms) and I think I might be missing some codecs but I'm not sure...

    When I convert the avi to mpeg, it goes on for 40 min longer than it should (it's a 22 min file) and also there is no sound... Here's the information of the file I found on Virtual Dub

    Video Stream:
    Frame size: 576 x 384, 23 976 fps (41708 us)
    Length: 32233 frames (22:24:38)
    Decompressor: Divx MPEG - 4 Low-Motion
    Number of key frames: 923
    Min/Avg/max/total key frames per sec: 1103/15853/47979 (14290k)
    Min/avg/max/total delta frame size: 110/4672/82527 (142858k)
    Data rate: 958kbps (0.48% over head)

    Audio stream:
    Sampling rate: 48000Hz
    Channels: 2 (Stero)
    Sample precision: NA
    Compression: Fraunhofer IIS MPEG Layer-3 Codec
    Layout: 0 chunks
    Length: 56014 samples
    Min/avg/max/total frame size: no audio frames
    data rate: 129kbps (-1. #J% overhead)

    Any help would be appreciated^^ I'm currently downloading tsunami filter pack 399 but after getting the codecs, where do u put them?

    Thx in advance

    Your .AVI contains a Variable Bitrate (VBR) .MP3 audiostream, which TMPGEnc cannot process. You'll have to convert it to Constant Bitrate (CBR) .MP3 audiostream as follows:

    Simply use NanDub (or VirtualDubMod) to save the audio stream as an Uncompressed PCM (WAV) file as follows:
    Load your original .AVI into NanDub
    Set "Video" to "Direct Stream Copy"
    Set "Audio" to "Full Processing Mode"
    From the "Audio" dropdown menu, select "Compression" - and choose "No compression(PCM)"
    From the "File" dropdown menu, select "Save WAV" (Enter a new filename with a ".WAV" extender).Click on "OK"
    Then set "Video" to "Direct Stream Copying"
    Then save the .AVI as a silent .AVI (set "Audio" to "No audio" after you've saved the WAV file).

    Then close NanDub and restart it
    Set "Audio" to "No audio"
    Load your silent .AVI
    Set "Video" to "Direct Stream Copying"
    Under "Audio" click on "WAV Audio" and load your .WAV
    Set "Audio" to "Full Processing Mode"
    From the "Audio" dropdown menu, select "Compression" and choose the appropriate .MP3 settings. Click on "OK"
    From the "File" dropdown menu, select "Save as AVI" and save your file with a new filename.


    You can then load the silent .AVI (first) and the .WAV audio file (second) into TMPGEnc...

        "Wow sounds complicated"

        Not really, just a lot of words (Hopefully the stpe-by-step instructions actually make it simple)


        "Thx for the help!"

        My pleasure ;>}
