Comments.Text: On the Photo.SE site a [very similar question](http://photo.stackexchange.com/q/41260/9161) was asked and answered (by me). While not directly applicable to a video file, I think you should fairly easily be able to convert video to a series of images (with e.g. [ffmpeg](https://www.ffmpeg.org)), apply the correction to the images and combine everything back to a video again.

  (Asked by: username_0 on 2014-09-21)
  
  Is there a Linux command-line option to do lens correction on videos? (Either as a tool, or a collection of tools)
  
  Specifically, GoPro videos? I know I can do correction in GoPro Studio, but I need something that I can incorporate into a batch process.
