How to Translate a Video to English: Subtitles, a Dub, or Both (2026)

Whether it is your Spanish channel, a German course, a Japanese interview, or an old family video, English speakers can follow it with English subtitles, an English dub, or both. This guide helps you pick the format, then walks through each route.

Quick answer

• Choose subtitles if viewers come for the person, a dub if they come for the information, or both to grow in English markets.
• Upload the video; the spoken language is detected automatically.
• Translate the transcript to English and review names, numbers, and idioms.
• For a dub, each speaker is cloned and keeps their own voice in English.
• Export burned-in captions, an SRT or VTT file, or a finished English dub.

Step 1: Choose English subtitles, a dub, or both

Subtitle it if the viewer is there for the person: their real voice, their emotion, their exact words. Dub it if the viewer is there for the information and needs to watch the screen at the same time.

	English subtitles	English dub	Both
Viewer gets	Original voices, English text	Speakers heard in English	English audio and text
Review effort	Read the lines	Read, then listen	Both, from one translation
Original performance	Kept in full	Voice cloned, delivery new	Dub replaces it, captions follow
Works with sound off	Yes	No	Yes
Best for	Interviews, documentaries, film, family videos, short social posts	Courses, tutorials, explainers, product videos	Channels and courses growing in English

For a more general take on the two formats, see Sub vs Dub: What "Dubbed" Actually Means.

Which format fits your type of video

• Your own YouTube or social content: both. Burned-in English captions help on mobile and sound-off feeds, and an English dub lets new viewers watch without reading. How to Add Subtitles and Dubbing to YouTube Videos covers uploading caption files and extra audio tracks.
• A course or tutorial: dub. Learners need their eyes on the screen, the code, or the slide, and reading captions while following a demo splits attention. Add English subtitles on top for accessibility. Our guide on how to dub an online course covers the lesson-by-lesson workflow.
• An interview or podcast episode: subtitles first. Viewers usually want the guest's own voice and tone. A dub works too, and each speaker keeps their own voice, but subtitles are the safer default where exact wording matters.
• A documentary or film: subtitles. The exception is a piece for children or one that is mostly narration, where a narrated English dub can work well.
• A family or personal video: subtitles. They keep Grandma's actual voice, which is usually the whole point, and they are the quickest to check.

Step 2: Check your rights and prepare the source

Three things to sort out before you upload:

1. Rights. Translating and republishing a video you did not make needs permission from whoever owns it, and dubbing also clones the speakers' voices, which needs their consent. Your own videos and licensed videos are fine. Is AI Dubbing Safe and Legal? covers the details.
2. The cleanest copy you have. Transcription accuracy depends on the audio. Heavy music, crosstalk, and wind noise cost accuracy, and in a dub they also affect how well each voice is cloned.
3. The source language, if you know it. The spoken language is detected automatically, but setting it yourself removes one thing that can go wrong, especially on short clips or videos that open with music.

Step 3: Make English subtitles

Use the Subtitle Generator for this route. It leaves the original audio untouched and gives you English captions.

Import the video

Upload a video file (MP4, MOV, MKV, or WebM) or an audio file. On the desktop app you can also paste a YouTube URL. Leave the language on auto-detect or set the source language yourself.

Transcribe in the original language

The speech is transcribed in its own language into timed lines with word-level timestamps. Transcribing in the source language first keeps the timing accurate, because every English line inherits the start and end time of the words it translates.

Translate the captions to English

Choose English as the translation language. The timed lines are translated, giving you an English caption track that lines up with the original speech.

Review the English lines

Read the captions through while watching the video. Machine translation is strong on clear speech, but check names, numbers, and idioms (see the review checklist below). If one line comes out wrong, regenerate it on its own instead of re-running the whole file.

Export the captions

Pick the format that fits where the video is going:

• Burned-in captions ("Download with subtitles"), styled with caption or karaoke-style highlighting, background boxes, fonts, and reusable presets. Best for social platforms where you cannot attach a caption file. See burn subtitles into a video.
• An SRT or WebVTT file for YouTube, a course platform, or your editor, so viewers can switch captions on and off. See SRT files and VTT files.
• A transparent caption video (Animation .mov, ProRes .mov, or WebM) to lay over your footage in any editor, or an After Effects .jsx script.

Not sure whether to burn captions in or ship a separate file? Burned-In vs Closed Captions walks through the tradeoff.

Step 4: Make an English dub

Use Video Dubbing for this route; English is one of its 21 dubbing languages. The full workflow, lip sync advice, and pitfalls are in How to Dub a Video Into Another Language. Here are the English-specific parts.

Import the video and pick English

Upload the video and choose English as the target language. The speech is transcribed and translated, and the transcript stays timed to the original audio.

Edit the English translation before you generate

The transcript and the English translation are both editable, and this is the most valuable five minutes of the process. Fix names, terms, and phrasing here, before any audio exists, and every later step inherits the fix.

Check the speakers

Each speaker is detected, separated, and cloned automatically from the source video, so they keep their own voice in English. To give someone a different English voice, assign one you designed or one from the library, or switch automatic cloning off and choose every voice yourself.

Decide on lip sync and generate

Turn lip sync on for talking-head footage with faces on camera, and leave it off for voiceover, screen recordings, and b-roll. Then generate. Lines are sped up or slowed down to fit the original timing, and the original background music and sound stay under the new English dialogue.

Listen, fix, and export

Watch the dub through once and regenerate any segment that sounds off without redoing the rest. Then export a finished video, the English audio on its own (for example, as an extra audio track on YouTube), SRT or VTT subtitles, or the subtitles as a transparent overlay.

Step 5: Release both from one translation

When you dub, the subtitles come from the same translated transcript, so the English captions match the English audio word for word. Viewers notice when captions say one thing and the voice says another, which is what happens when you subtitle and dub in two separate tools.

For a "both" release, generate the dub, style the English subtitles, and export a finished video with captions burned in, or the video plus a separate SRT or VTT file.

English review checklist

A quick read-through catches most of what automatic translation gets wrong. These trip up translations into English in particular:

• Names and brand terms. Machine translation sometimes treats a surname or product name as an ordinary word. Search the English text for every name in the video.
• Numbers and formats. Many languages write 1.500,50 where English writes 1,500.50, and dates run day first. Pick American or British English and keep dates, units, and spelling (color or colour) consistent.
• Numbers in a dub. Voice Creator Pro reads numbers, dates, and currency correctly, so check that the translated figure is right rather than how it will be pronounced.
• Formal and informal "you". German, French, Spanish, and Japanese mark politeness in ways English does not. The translation often comes out correct but flat, and a small rewrite restores the tone.
• Idioms and jokes. A literal idiom reads as nonsense in English. Replace it with the English equivalent or its plain meaning.
• Subtitle line length. English is often more compact than the source, but long sentences still need splitting. As a benchmark, Netflix's English subtitle guidelines (checked September 2026) allow up to 42 characters per line, two lines, and up to 20 characters per second for adult programs.
• Pacing in the dub. Shorter English lines may be slowed to fill the original gap. If a line sounds stretched, add a word or two of natural phrasing and regenerate it.

Free ways to translate a video to English

Free tools cover some cases, based on their own help pages as of September 2026:

• YouTube auto-translated captions. On a YouTube video that already has captions, a viewer can open Subtitles/CC, choose Auto-translate, and pick English, at no cost. It only works inside YouTube's player and depends on the video having captions, and you get nothing to download, edit, or burn in. YouTube's help notes that automatic captions "might misrepresent the spoken content due to mispronunciations, accents, dialects, or background noise".
• YouTube automatic dubbing. Creators can have YouTube generate dubbed audio tracks for videos on their own channel, including into English from a range of source languages, and it is on by default for eligible creators. Per YouTube, videos over 120 minutes or with copyright claims are not eligible, and the dubs "might contain errors". The YouTube guide linked above compares it with making your own track.
• Google Translate. Good for checking a sentence or translating a transcript you already have. It does not take video or subtitle files: document translation accepts .docx, .pdf, .pptx, and .xlsx up to 10 MB. Pasting an SRT's text in means rebuilding the timing and checking no timestamps were mangled, which gets slow fast.

The free route works for watching someone else's YouTube video in English or checking what a clip says. Once you need a file you own, captions you can style, or a dub you can publish anywhere, you need a tool that does the whole job.

Free vs paid in Voice Creator Pro

You can translate a video to English with subtitles or a dub on the free Voice Creator Pro Cloud tier, in your browser. English SRT and VTT caption files download without a watermark; dubbed videos and burned-in subtitles carry one, and every paid Cloud plan, starting with Starter at $5 a month, removes it; see pricing for the current tiers.

The desktop app is a one-time purchase that runs transcription, translation, and dubbing on your own computer with unlimited generations. On desktop, the Subtitle Generator can also take a YouTube URL. Either way, you own what you export, with commercial rights on every tier.
