Cloud Atlas 2012 Bluray Hindi English X264 Aac ... [new] -

If you legally own the BluRay (English) and a separate Hindi audio track from a legitimate source (e.g., a purchased TV broadcast), you can use free software like to remux both audio tracks into one MKV file. This is legal for personal backup in most jurisdictions, provided you do not distribute it.

Just let me know what you need.
