Sometimes you need to fiddle with your media before adding them to Plex. Tools to help with modifying your source material. So here is a list of the (free) things I use most frequently (In no particular order).
- Handbrake
Use this if you want re-encode your files and you don’t like the command line. Most of what you can do with this can be done with ffmpeg. - ffmpeg
A command line alternative to Handbrake. - MakeMKV
Extract your Discs to MKV Files. - MP4Box
Does Stuff… I find it useful to clean up / remove metadata from mp4 files, simply run your files through this and your pesky metadata is gone. - MKVToolNix
Handy toolkit of mkv things. Can Join Files, can remux from mp4 to mkv. As I have mentioned before I prefer to use mkv files, so when I come across mp4 files I simply remux them to mkv with this.
