I just happened to think about this:
If anyone is as annoyed as I was about Handbrake appending (-1) to every single file, open Tools/Options/Output Files and whack that second tag in the Format window (I can’t remember what it was now) so it looks like this:
Note:
Handbrake will complain if you insist on overwriting your original file to the point that it just won’t do it, but it’s a DARN good idea to set your Handbrake destination folder to a place where all your Handbrake files go. I have cryptically created a folder called ‘Handbrake Dumps’ on my local ‘work drive’ and aimed HB at it. Everything I drag into HB comes from somewhere else - and it’s a good idea to create another folder to put stuff in you want to Handbrake - something like ‘Handbrake Deck’.
I also have one or more ‘On Deck’ folders on every drive to drag large files into before moving them into my libraries - so they’ll instantly show up in the library and not be part-way in when Plex notices them.
