Assuming it's an avi file containing compressed data, not an avi file that
itself has been compressed ('zipped')-
Try simply feeding them into ffmpeg and see what comes out- e.g. "ffmpeg -i
inputfile.avi outputfile.mkv" (or .mp4 etc). If you don't get anything nice,
post the complete output of the command to this list (and use an up-to-date
ffmpeg, not one that's years old; check ffmpeg.org).
You can also use ffprobe to see what's inside the file.
After that, it's all about picking an output file format, and may if the
common ones use lossy compression to make the data smaller.
