Comment 8 for bug 574870

Put that script in $HOME/bin, and the attached nautilus script in .gnome2/nautilus-scripts (make it executable with 'chmod u+x'). Then select a folder where the files are and from the context menu (right button) select the script. It'll move the files to $HOME/Videos (I changed it now to use XDG_VIDEOS_DIR, so that part is untested but should work), and renames them as YYYY-MM-DD_HHMMSS_LENGTHsec.mts. Feel free to change the renaming from the import-avchd script.

Note that this has only been tested on files from my Canon HF200. I'm interested to find out if the metadata parsing works on files from other camcorder vendors.
