If your movie editing software does not directly import mpeg files from your digital camera, you might need to convert them to dv in order to import in for example into iMovie.
mpeg2dv.sh anMpgFile.mpg anotherMpgFile.mpg
The result should be .dv files in the subfolder in question.
#!/bin/sh
# This script converts mpeg files from a digital camera
# into the DV format using the ffmpeg tool.
