Asked By 70 points N/A Posted on -

Hi Ally,

A work a lot with Virtual Dub, but now I am facing a problem. When I try to append one .avi file to another .avi file, I ended up with an error message. How to append a file in Virtual Dub? I have been spending time in the internet to search for a solution. Please explain me in detail. Your help is great. Thanks.

The audio steams have incompatible data formats


I edit and combine videos from time to time but the software I used is not that strict when combining different videos where each may have different audio stream format. In a video file like AVI, the audio data of the video is composed of different components that complete the entire audio data stream.

The audio component can use different audio codec such as mp2, mp3, pcm_s16le, and so on. The bitrate of the audio data can use or can be set to 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320, 384, and 448. The sample rate can be set to anywhere from 8000, 16000, 22050, 32000, 44100, and 48000.

For your information, all these facts were based on the program I am using, ImTOO MPEG Encoder Platinum 5.1.26.

The channels can be set to a single channel or mono, two channels or the stereo, 5.1, and so on. If VirtualDub is complaining about incompatible data formats maybe your AVI files don’t use or are not on the same stream level. I think the only problem you got here is only the audio part of the file and the video is just fine.

To fix your problem, you need to convert one of the files to match the other so they use the same audio stream level. If one file is set to use mp3, 128 kbps at 44100 Hz in stereo, you need to convert the other AVI file to the same stream level. Try using ImTOO MPEG Encoder to do this.
