title: Modifying Creation Date from Filename for mp4 videos
body: <p>I have a bunch of DV avi videos which I want to cut together. I managed to save the Creation Date out so the videos are named after their creation date. So after I cut them together, I still have the original date of the creation. But then I would like to put that date back to the metadata, which is modified after being cut together and converted from DV avi to mp4.</p>
  
  <p>I am trying with exiftool, but I am a total noob and I cannot use it properly.
  The final question is. Is there a possibility to batch change the "date created" metadata from the filenames?</p>
  
  <p>the filename looks like this: YYYY-MM-DD-HH-MM-SS.mp4
  I want to put it into the date created metatag.</p>
