Hello,

I have a question about editing an avi file in matlab. I managed to read in the avi-file (the video data), edit it, and write it back to another avi-file. The problem is, the audio data is lost...
So my question is, how can I extract the audio data from an avi, and how to store it with the video data when writing it back to an avi-file after editing.

I hope someone can help me with this!

Hi Bert,

System objects from the Video and Image Processing blockset are capable of reading and writing AVI files
including the audio.

See the following pages:
