• Official dubbing: Studios or licensed distributors produce professional Hindi audio tracks for theatrical releases, TV premieres, and streaming platforms. These preserves original visuals and most dialogues, replacing voice performance and often localizing idioms.
• Subtitling: Original English audio is retained while Hindi subtitles make content accessible to non-English speakers or multilingual households.
• Unofficial/bootleg dubbing: Fan-made Hindi dubs and pirated uploads circulate on file-sharing sites and some streaming portals — lower quality and often illegal.
• Remakes/adaptations: Indian filmmakers remake Hollywood stories, adapting plot, characters, music, and cultural context into Hindi-language films (e.g., official or unofficial inspirations).
• Curated streaming: OTT services and TV channels acquire rights and present catalogs targeted at Hindi audiences, sometimes offering Hindi audio and UI localization.
