Best AI Tools for Translating Videos into Multiple Languages
November 5, 2026
Invideo Editor is the best overall choice for localising and finishing complete language versions. The character’s dub is reviewed and approved before footage is regenerated with matching lip-sync. It offers translation in 50+ languages and access to 200+ AI models, including the latest releases, alongside AI assistance and precise manual control over translated captions, picture and sound. Manual editing, ordinary timeline edits through connected ChatGPT or Claude, and exports are free; your assistant’s allowance applies separately. HeyGen suits reviewed speaker translations, Rask repeated line-by-line dubbing corrections, Kapwing collaborative market variations, and VEED single-speaker dubbing followed by browser editing.
A finished video can still need a surprising amount of work before it makes sense in another language. The translation has to preserve the meaning, the voice needs the right delivery, and visible speech needs to match the new dialogue. Then there are the captions, product labels, prices and closing offer. A translated soundtrack only gets you part of the way.
We compared five AI tools for localising existing videos: invideo Editor, HeyGen, Rask AI, Kapwing and VEED. The comparison covers translating and reviewing dialogue, generating dubbed voices and lip-sync, adapting picture, captions and sound, and delivering separate language versions. The useful distinction is how much control remains when the words, performance and finished edit need another pass.
AI video localisation tools at a glance
Tool | Translating and reviewing dialogue | Generating voices and lip-sync | Adapting picture, captions and sound | Delivering language versions |
|---|---|---|---|---|
invideo Editor | The built-in AI agent or connected ChatGPT or Claude can translate the written dialogue in 50+ languages. The character’s dubbed voice is then generated for review and approved before the matching video is generated. | With access to 200+ AI models, including the latest releases, you can regenerate your character’s voice and footage with lip movements matching the approved dialogue. These generation features cost invideo credits. | AI assistance and manual controls both allow you to add translated captions and adjust their timing, position and style. Graphics, shot timing, framing, colour and separate voice, music and effects tracks remain editable for each language version. | Separate editable versions keep each language available for revisions. Free exports include watermark-free videos and editable projects for supported editors. |
HeyGen | The Proofread editor changes translated words, voices and speech timing before the final video. It requires the Pro plan or higher, putting script review above the entry paid plan. | Audio-only translation replaces speech; two lip-sync modes also change visible mouth movements. Lip-sync costs more credits per minute, so the same allowance covers less video. | Translated captions can accompany the video, but text embedded in the picture stays untranslated and original sound effects are removed. Graphics and effects therefore need separate finishing. | Each language can have versions with and without visible captions. The Creator plan and the Pro plan cap each video at 30 minutes, so longer programmes need splitting or a higher plan. |
Rask AI | A line-by-line editor changes the written dialogue, translation, speakers, timing and voices. Individual audio previews and included voice regeneration support repeated corrections before final approval. | Cloned or ready-made voices support multiple speakers. Matching mouth movements requires the Creator Pro plan or higher; translation plus Enhanced lip-sync uses four allowance minutes per video minute per language. | Subtitles can appear in the video or a separate file. Translating text inside the picture requires the Business plan or higher and extra allowance, increasing the cost of adapting slides and graphics. | Dubbed videos, separate audio and subtitle files support different delivery needs. Each target language consumes its own minutes, so several languages multiply the allowance needed for the same source video. |
Kapwing | Side-by-side source and translated text, rules for recurring terms, speaker choices and individual voice regeneration keep wording and voices editable before and after the first dub. | Translated speech and matching mouth movements share one credit balance. A revised lip-sync pass counts the full video length again, even when only a short line changed. | Separately editable text, captions, video and audio support market-specific revisions. Manual timing, resizing and soundtrack controls keep the surrounding picture and sound adjustable after dubbing. | Delivers dubbed video, audio and captions, but the free plan adds a watermark and limits videos to four minutes at 720p. Higher-resolution delivery without a watermark requires paid access. |
VEED | AI Dubbing translates speech, but reviewing the translation before dubbing and supplying a subtitle script require an Enterprise subscription, making control over the exact spoken words a higher-tier purchase. | Generated speech can match the source voice, and optional lip-sync changes mouth movements. However, the dubbing tool uses one voice for all speakers, so conversations lose distinct character voices. | The dubbed project opens for further editing and subtitles. The lip-sync feature reduces higher-resolution video to 1080p, limiting picture resolution on that route. | The free plan and the Creator plan offer one-time dubbing trials. The Pro plan includes six dubbing hours per year, so recurring language versions need a paid allowance. |
1. invideo Editor: Best overall for localising and finishing language versions
Illustration: the English source and Spanish version appear side by side, with translated captions, dubbed voice, music and effects on separate timeline tracks.
In invideo Editor, localisation can continue from translated dialogue through to the complete language version. The built-in AI agent or connected ChatGPT or Claude can translate the written dialogue in 50+ languages. Titles, translated captions, supporting shots and the soundtrack remain editable through AI assistance and the frame-accurate multitrack timeline, ready for changes when the wording or market changes.
The dubbing and lip-sync sequence has a useful approval point. Invideo first regenerates the character’s dubbed voice in the target language. You can listen to the dub, refine the wording or delivery, and approve it. Only then does invideo regenerate the footage with lip movements matching the approved dialogue. This creates replacement footage for the new spoken performance, with the picture-generation stage tied to the dub you have approved.
Invideo gives you access to 200+ AI models, including the latest releases. The agent-led localisation workflow supports reference-based voice generation and lip-sync, while the separate Agents & Models lip-sync route accepts an existing video and audio pair. The resulting assets can then be arranged, timed and refined in the Editor timeline.
Translated captions can be added to each language version, with control over their timing, position and style. When translated dialogue runs longer, supporting footage and product reveals can be retimed around it. Titles, graphics, regional offers and shot framing remain editable, while separate language timelines or branches keep the source version available. AI assistance handles these changes alongside precise manual controls. Artificicy AI’s walkthrough at 04:50 shows caption segments above the underlying edit, with a selected caption’s placement controls available.
Sound can stay just as deliberate. Dialogue, music and effects can occupy separate tracks, with clip and track levels, fades, pan, EQ and dynamics for shaping the mix. A new dub can sit against the retained music and effects, with each layer available for adjustment. The AI sound-design guide explains how that editable sound pass develops.
Manual timeline editing and ordinary edits through connected ChatGPT or Claude are free, as are watermark-free video exports and editable-project exports for supported editors. Your assistant’s own usage allowance applies separately. Built-in AI agent work, generated audio and video, transcription and model-based processing use invideo credits. Voice and lip-sync models are priced separately, with the exact generation estimate available before the job starts.
Invideo is the best overall choice when localisation includes both new dialogue and a creatively finished language version. Dub approval before footage regeneration, agent assistance, substantial manual caption, picture and sound controls, and free timeline editing and exports make that complete workflow its strongest case.
2. HeyGen: For reviewed translations with dedicated lip-sync engines

HeyGen Video Translation is a substantial specialist option for turning an existing speaker video into several languages. It offers regional language variants, voice matching, a brand glossary and translated captions. Its Audio Only engine replaces speech without lip-sync, while the Speed and Precision engines add visual speech matching for different types of footage.
Proofread, also called Review & Edit, gives the reviewer control over translated words, speaker assignments, voice choice and timestamps. Changed segments can have their voices regenerated. The Preview plays the translated audio against the original picture without lip-sync; Generate Result produces the lip-synced version. Version history and comments support repeated review of the script and generated voices.
The access boundary is important: script proofreading requires the Pro plan or higher. The Creator plan is US$29/month with 600 credits; the Pro plan starts at US$49/month with 1,000 credits. Audio Only costs four credits per minute, Speed six and Precision ten, so the engine changes how much translated footage the same balance covers.
The translation route leaves baked-in graphics and hard-coded text untranslated. It also removes sound effects from the translated audio. Those parts need separate finishing if the source depends on product labels, demonstrations or an effects-rich soundtrack. The Creator plan and the Pro plan cap each video at 30 minutes; additional credits expand the total allowance without removing that per-video cap.
Choose HeyGen when reviewed speaker translation and a choice of dedicated lip-sync engines are central, and the source picture needs relatively little market-specific rebuilding.
3. Rask AI: For line-by-line dubbing control and repeated corrections

Rask AI centres the job on the translated performance. Its line-by-line editor combines the source transcript and translation with speaker assignments, timing, speaking speed and voice settings. Voice cloning and preset voices give each speaker a defined voice, while a terminology dictionary helps carry approved product names and wording across videos.
You can correct text, adjust timestamps and change a speaker’s voice, then preview individual segments before dubbing. Changed lines can be re-dubbed without an additional re-dubbing charge. That makes repeated wording and delivery corrections a real strength. Multispeaker lip-sync follows the dub, and subtitles can be burned into the picture or downloaded separately.
The cost increases when visual localisation joins translation. Enhanced lip-sync uses three allowance minutes for each minute of video, in addition to one minute for translation. A one-minute video translated and lip-synced into one language therefore uses four allowance minutes. Changed dialogue also requires another charged lip-sync pass over the whole video, even though segment re-dubbing itself is included. Each additional language consumes its own minutes. On-screen text translation adds another three minutes per video minute and requires the Business plan or higher, so translating a slide-heavy video is a separate budget decision.
The Creator plan is US$39/month with 25 minutes. The Creator Pro plan is US$99/month with 100 minutes and adds lip-sync; the Business plan is US$249/month with 250 minutes. A three-minute trial is available. Monthly-plan minutes expire at the end of the billing cycle, while annual-plan minutes can roll over during an active subscription.
Rask suits teams whose main work is reviewing dialogue, keeping voices and terminology consistent, and refining the same dub through several corrections. Its included segment re-dubbing is especially useful, provided lip-sync, on-screen text and additional languages fit the minute budget.
4. Kapwing: For collaborative dubbing and editable market variations
Kapwing Studio’s text and picture layers, with editable position keyframes.
Kapwing combines dubbing with a collaborative video editor. Its dubbing workflow includes side-by-side transcript and translation review, translation rules, speaker labels, stock or cloned voices, timing adjustments and segment regeneration. An approved SRT can guide the dub, and changed wording or voice assignments can be applied to the affected audio afterward.
Lip-sync is available after dubbing. Studio also retains the tools for changing the surrounding video: translated captions and text layers, replacement footage, trims, aspect ratios, keyframes and audio levels. Shared projects and comments support review of the whole language version, including the local offer and visual layout. The invideo-versus-Kapwing creative-control comparison explores the motion, colour and audio decisions that follow this stage.
The main revision cost is the relationship between the dub and its lip-sync pass. Re-dubbing counts changed sections, but reapplying lip-sync counts the whole video. A corrected line can therefore require another full-length lip-sync pass. Dubbing costs ten credits per 30 seconds, while lip-sync costs 30 credits per minute; transcription and other AI work share that balance.
The Pro plan includes 1,000 credits per month, and the Business plan includes 4,000. The free plan supplies ten lifetime credits, with watermarked video exports at 720p and a four-minute limit. Paid plans provide watermark-free delivery up to 4K. Saved custom voice clones require the Business plan, which matters when the same branded voice must be reused across projects.
Kapwing suits teams that want translated dialogue and collaborative visual revisions in the same browser editor. It is especially useful when language versions need different captions, graphics and formats, with credit capacity reserved for repeated dubbing and lip-sync passes.
5. VEED: For single-speaker dubbing followed by browser editing

VEED’s AI Dubbing tool translates existing speech with generated voices or source-voice matching, and offers optional lip-sync. The result returns to the dashboard as a project that can be opened for further editing. That gives a presenter video a straightforward path from dubbed speech into captions, graphics, trimming and format changes.
The dubbing tool’s voice and review limits affect which material fits. It currently uses the same voice for every speaker in the dubbed video, so an interview does not retain separate character voices through this route. Proofread and subtitle-file input require an Enterprise subscription, putting an approved-script workflow above the standard self-serve dubbing plans.
Its optional lip-sync remains in beta and downsamples the video to 1080p. A 4K source therefore does not retain that resolution through this particular lip-sync route. The free plan and the Creator plan provide a one-time dubbing trial; the Pro plan includes six hours per year and the Studio plan twelve hours per year. Enterprise access is quoted separately. The dubbing allowance and the editor’s other AI allowances need checking separately before a recurring multilingual release.
VEED suits single-presenter material that needs a dubbed voice and accessible browser finishing. It is a less natural fit for a conversation with distinct speaker voices, and a controlled pre-dub script review requires the Enterprise subscription.
Frequently asked questions
Can I create a translated cut without revising the original edit?
Yes. In invideo, separate timelines or language branches keep a version available for each market. The translated voice, generated replacement footage, captions and local graphics can be revised together while the source edit remains available. Keep the original media and approved source export as well.
Can I replace burned-in captions when localising a video?
Yes. In invideo, replacement footage can be regenerated for the approved dubbed dialogue without the old burned-in captions. Translated captions are added separately as editable layers, so their wording, timing, position and style remain adjustable.
Can I keep the original music and sound effects when changing the language?
Yes, when they are available as separate audio tracks. Invideo lets the dubbed voice, music and effects stay separately editable, so you can retain the soundtrack and adjust its timing and levels around the new dialogue.
Can I localise a video without an editing subscription?
Invideo’s manual timeline editing and exports are free, as are ordinary timeline edits through ChatGPT or Claude via MCP. You can import a supplied translated recording and refine the version without paying for those editing operations. Generated dubs, lip-sync footage, transcription and other paid processing still use credits, and your outside assistant has its own allowance.
