If you're not wanting Remux Rips I'd really suggest converting your files to H.265, it's got much better compression ratios than H.264. You can set up tdarr or fileflows (fileflows is much easier if you don't want to write the ffmpeg yourself) to run through your library and automatically run conversions on new files.
I use it to also strip foreign language tracks from files where it's neither the primary track nor original language
