I just saved 1.3TB on my storage pool by stripping all the foreign language audio tracks from my movie and TV files. Many of us download Remuxes for the amazing lossless video quality but it also comes with multiple foreign audio tracks depending on where you source them. I know many of you have files that also have Italian audio tracks or Russian that take up space.
Can you imagine how tidious it is to do this manually to every file that fits this criteria let alone pin pointing which even have multile audio tracks? Seems impossible considering thousands of files. I'm here to tell you all this can be done in 1 click. How did I do it?
I used Grok Bot. Grok bot will automate all of this so you just give it the instructions on what you want it to do. It verifies all the tagged files and how much space you'll save. Here are the rules list i've curated with my experience doing this. You could just copy and paste this and see what it tells you for your setup:
FOREIGN AUDIO STRIP RULES
WHAT GETS STRIPPED
- Strip non-English audio tracks from media on (Enter Your Drive Letter) (remuxes included).
- Strip non-English subtitles only from files already being rewritten to remove foreign audio.
Never rewrite a file just to drop foreign subs (saves no real space).
WHAT STAYS
- English audio (main, commentary, descriptive) and English subs, including forced English.
- If a film has no English dub: keep its original-language audio plus English subs.
- Foreign-language films keep their ORIGINAL-language audio even if they also have an English dub
(e.g. Seven Samurai, Ran, Audition, The Raid 2, Grave of the Fireflies, The Lives of Others).
Only extra dubs get stripped, never the film's original language.
HOW IT'S DONE
- Lossless copy only (ffmpeg -c copy): no re-encode, video/HDR/Dolby Vision untouched.
- Each new file is verified (duration, tracks, chapters) before it replaces the original;
if verification fails the original is kept.
AFTERWARD
- Remove language tags (Ita, Rus, 2xRus, Hindi, Korean, Latino, Multi, etc.) from the folder
and main file names so they match the remaining tracks. Keep all other release info.
My scan ran for about 2 days in the background and saved 1.3TB of space. It's worth a look for your drive and see how much you can save for foreign audio tracks you'll never use.
