• ffmpeg bash script to generate thumbnails for all videos in a folder

  17 novembre 2017, par smokeyone

  I found this bash script via google and would like to modify it slightly to generate jpg thumbnails from a desktop folder call indie. All my mts files are named by their exact time taken and ffmpeg is installed.

  This is the original script :

  for f in *.mov; do
  
      ffmpeg -y -i "$f" -f image2 -ss 10 -vframes 1 -an "${f%.mov}.jpg";
  
  done

  I changed it to this :

  for f in Desktop/indie/*.mts; do
  
      ffmpeg -y -i "$f" -f image2 -ss 10 -vframes 1 -an "${f%.mts}.jpg";
  
  done

  I am hoping someone can tell me where I have gone wrong (my terminal output just says no such file).

  Thanks
