FFMPEG would probably be my first choice, since you can adjust/convert many things from the command line. That being the case, a simple script to loop through and set the volume to xxx level wouldn't be too hard. It has a volume normalizing feature already, but you can manually do it as well:
Code:
ffmpeg -i input.mp4 -filter:a loudnorm output.mp4
ffmpeg -i input.mp4 -af "volume=5dB" -c:v copy -c:a aac -b:a 192k output.mp4
May have to play with codecs, since AVI's may be different than MP4's, or you could just simply convert all the files to MP4's and use the AAC codec. Read the man page on ffmpeg.
