Re: create .avi files from different video and audio streams

> Hi, You should see that when you construct your video.MultimediaFileWriter System object (I recall you're using R2010a) that the VideoCompressor and AudioCompressor (available if the AudioInputPort property is true) properties are set to 'none'. This means the file you write is uncompressed.

Thanks Wayne. I understood the concept. I am able to use compression but the results are not good. I want to use xvid codec in matlab. I downloaded and installed xvid codec but it is not getting listed. Please help me out in this matter.
