Use Automator to change recording date of video-files

[Art-art]

Hi, I'm quite new to automator and got stuck right away in my effort to solve the following:

While copying movie-files in iMovie from one drive to an other iMovie changed the recoding date as listed within the file to the date of the actual file on the drive. Luckily most filenames are like 'clip-1999-12-22 17;21;54.dv' and others like 'Generic_name2003_0621_202457AA.avi'. This information is exactly what's needed to update the EXIF information.

Now I would like to use the filenames to update the recording date within the file (is this EXIF information?).

The flow I expect I have to make is something like:

1. Read filename
2. Extract year, month, date, hour, minute and second from the file name
3. Update the EXIF information with the information extracted from the file name
4. Store the updated file

Any idea if this is possible? Any suggestion is welcome.
