Virtualdubmod – Huge converted AVI file

I have a 700MB avi file with two audio streams. I used Virtualdubmod to get rid of one of the streams (I disabled one in the stream list and did a File - Save as). The new avi file with a single audio stream was 77 Gigabytes long.

How can I get it down to something more reasonable.

You have to choose “Direct stream copy” in the video menu. The same has to be done with the remaining audio track (this is the default). By choosing “Direct stream copy” you copy the video stream without recompression. You have selected either “Full processing mode” or “Fast recompress”, but didn’t specify any codec for recompression. In this way you have generated a giantic uncompressed video stream.

Thanks a lot. It worked.
