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.

Instructions

コードをデスクトップに保存します。拡張子が本当に .sh になっていることを確認します。(.sh.txt になってしまっている場合があります。)

Place the script in a proper place like /usr/local/bin/mpeg2dv.sh on Mac OS X or for example ~/bin/mpeg2dv.sh on Linux that is in your $PATH environment variable and make the script executable if needed.

端末 (Mac OS X ではアプリケーションフォルダーのユーティリティ内) を開いて以下を入力します:

mpeg2dv.sh anMpgFile.mpg anotherMpgFile.mpg

The result should be .dv files in the subfolder in question.
