Generate Thumbnails in parallel - Inefficient implementation does not scale to 200 TB MKVs

Hi @rithram,
wait - you are talking about 200TB of data?! Why on earth would anyone need so many movies??
Well, apart from that, you have (I believe) two options:

  1. Just disable video thumbnail generation. Go to your library, three dots, manage, edit, advanced, disable video thumbnail generation.
  2. Create / download your own thumbnails and calling them like the original movie but replace .mkv with .jpg or .png or anything you like really (“Movie_ABC.mkv” <-> “Movie_ABC.jpg” automatically recognizes it as thumbnail) and throw them in the same folder.
    2.5. If you have very few but huge files (e.g. surveillance) you can manually select a thumbnail by going to each video and pressing the edit icon, though I don’t know if that automatically opens up another thread or if this just prioritizes this thumbnail (cancels previous one and cares about the one you’re currently editing).
    Hope this helps
