How to translate a video into another language: subtitles, auto-dub or your own voice

Whatever your niche, a video that worked in one language can work in another. There are three ways to translate it. Here’s what each one takes, which languages it covers and when to use it.

Three ways to translate a video, compared
	Translated subtitles	Platform auto-dub	Dub in your own voice
Viewer has to read	Yes	No	No
Works on mute	Yes	No	With captions on
Languages	Any you can translate	YouTube: 20 from English. Reels: 9	600+
Where it works	Anywhere (burn-in or .srt)	Only on that platform	An MP4 you post anywhere
Effort	Translate and time every line	One setting	Upload, pick a language

The three options at a glance. Sources: YouTube Help, Meta (January 2026) and the VideoVoice site. Details below.

First, pick one language

Start with one, not five. Look in your analytics for countries where you already get views in a language you don’t speak. That’s your first test.

Option 1: Translated subtitles

How: get a transcript, translate it, then time each line to the speech.
Keep lines short. Netflix’s style guide caps English subtitles at 42 characters per line and 20 characters per second for adult viewers (Netflix).
On YouTube: in YouTube Studio, open Subtitles, pick the video, click Add language, then upload a file or type them in (YouTube Help).
On TikTok and Reels: burning the captions into the video is the simplest way to make sure everyone sees them.
The VideoVoice Subtitles tool does both: a captioned MP4, or an editable .srt or .vtt file, with optional translation into another language.

The catch: viewers have to read while they watch. On a fast short-form video, that’s a lot to ask.

Option 2: The platform’s auto-dub

YouTube automatic dubbing: English videos can be dubbed into 20 languages, including Spanish, Hindi, Arabic, Japanese and Portuguese. Most other languages can only be dubbed into English (YouTube Help).
You can’t edit YouTube’s automatic dubs, and videos over 120 minutes, mostly music or with very fast speech may not qualify (same source).
Instagram and Facebook: Meta AI can translate, dub and lip-sync Reels into nine languages: English, Hindi, Spanish, Portuguese, Bengali, Tamil, Telugu, Kannada and Marathi (Meta, January 2026).
Why audio is worth it: YouTube says creators who added multi-language audio saw over 25% of their watch time come from views in the video’s non-primary language (YouTube Official Blog, 2025).
The catch: the dub lives on that one platform, in the languages it supports.

Option 3: A dub in your own voice

Upload a clip under 90 seconds, or paste a TikTok link, and pick from 600+ languages.
Your voice is cloned from the clip, so the dub still sounds like you.
The script is translated for meaning, not word for word. Background music is preserved and captions are generated.
You download a clean MP4 you own: post it on TikTok, Reels or Shorts, or start a channel in that language.

One voice, cloned from a single English take, speaking Arabic, Urdu, Turkish, Hindi and Spanish.

Which one should you use?

A long English video on YouTube, and your language is on their list: turn on automatic dubbing.
Your viewers often watch on mute: add translated subtitles. They help whichever option you pick.
A short clip for several platforms, or a language the built-in tools skip (Urdu, Turkish or Swahili, for example): dub it in your own voice.

Start with one video and one language. If the views come, translate the next one.
