which camera model is it? or do you know what codec the camera uses?
if you don’t know, in quicktime click movie, show movie inspector.
if it’s photo jpeg, it’s pretty straight forward
get mp4cam2avi
http://sourceforge.net/projects/mp4cam2avi/
unzip and run it. click settings, program mode, expert
on the right,
action: batch convert (many -> many, otherwise it combines them)
video: source video
audio: source audio
on the left, browse to where your videos are stored. if you want to select more than one file, hold the ctrl button while clicking each file. the output should be a bunch of AVI files in a subfolder named videoout. those should be openable in movie maker.
