| Do you have this problem with this movie only? It doesn´t look as a Vdub problem. Looks like a codec problem. If yours is a small movie you could "save wav" uncompressed, and then compress from the wav file |

| moved to codec discussion section Can you tell us exactly WHAT MP3 codecs are listed in your codec list ? Do you have to tick 'show all codecs' first to see them in the list, or do they show up on first opening ? What sampling rate is your audio track ? |

| Looks like the problem is in audio codec used in the avi file - VDub can't decode sound from the avi file. Therefore VDub can't offer suitable formats for encoding. I suspect there's something like AC3 - in this case you will see just the same picture - right box will be empty, because there's nothing to encode - source audio can't be decoded. You can tick box "Show all formats" and will see all possible formats for all codecs, but it's useless - you can't recode sound. Open your avi file in VDub, then look to "File" -> "File Information..." and tell, what you see in the section "Audio stream". |

| Hmm ... seems your audio is uncompressed PCM, sou you should be fine here, but why is the sample rate not precisely 44100 Hz but something like 44094 Hz ? Maybe this is the reason, as most audio codecs require a specific input sampling rate. IIRC there is a way to force the sampling rate to be 44100 Hz, but i cant remember how to do it right now ... guess i am getting old .. lol |

| Just go to "Audio" -> "Conversion" and select there 44100KHz. |
