  However you seem to have missed my complaint was about Handbrake batch processing not respecting hierarchies, that is it misses files in a folder hierarchy.

Title: Batch encode to X265 on the Mac
UserDisplayName: MiB
ThreadText: # Batch encode to X265 on the Mac
  
  (Asked by: username_0 on 2016-07-05)
  
  I need to encode thousands of MP4 H264 (mostly) files in a folder hierarchy to H265. Unfortunately Handbrake that I'd normally use have dismal support for batch processing of hierarchies.
  
  The separate project HB Batch Encoder doesn't seem to support X265.
  
  Preferably I'd want a method that can
  
  * Accept all source movie files in a selected hierarchy
  * Encode to X265 as good as Handbrake
  * Automatically pass thru AAC, re-encode any other audio
  * Output to the same directory as the source
  * Move the source to the Trash
  * Works on OS X 10.11
  
  Can you suggest a tool and method for this that achieves this set of features?

  [FFMPEG](http://ffmpeg.org) of course. Being a command line application it can be easily integrate into any batch process no matter how convoluted, with the benefit that you get to learn about the power of the command line while you're at it (worked for me).
  
  I haven't explored h.265 encoding much yet, but using settings I stole from the [ffmpeg wiki](https://trac.ffmpeg.org/wiki/Encode/H.265) here's how you'd encode a folder full of .movs:
  
  ```
  cd "/the/path to/your/folder/"
  mkdir "for the trash"
  for i in *.mov; do;
    ffmpeg -i "$i" -c:v libx265 -preset slow -crf 25 -c:a copy "${i/\.mov/.mp4}"
    mv $i "./for the trash/"
  done
  
  ```
  
  Note that this won't delete the files, it will move them to a new folder called **for the trash**. This is because if you delete files with the command line they disappear instantly, you don't get a second chance if you change your mind or make a typo. There are [trash command line utilities](http://hasseg.org/trash/), but that's beyond the scope of this answer.

  Handbrake [also works on the command line](https://trac.handbrake.fr/wiki/CLIGuide).
  
  And lastly if you are allergic to the colossal power lurking in terminal.app there are GUIs for ffmpeg, like [this](http://www.ffmpegx.com/) or [this](http://www.iffmpeg.com/index.html). Not sure how well they deal with batch encoding, and this is not a recommendation, because I don't use any of them. Time to toughen up and use the command line!
