Help:Mpeg2dv.sh/pt-br
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.
Instruções
- Salve o código para sua área de trabalho; certifique-se que a extensão seja realmente .sh, e não .sh.txt.
- 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.
- Open a terminal (Terminal.app on Mac OS X; it's in the Utilities folder of Applications) and type:
mpeg2dv.sh anMpgFile.mpg anotherMpgFile.mpg
The result should be .dv files in the subfolder in question.
