📄 About AI Video Translator
The AI Video Translator on JAI Portal turns any video into a fully localized, lip-synced version in 150+ languages — without studios, voice actors or subtitle hacks. Upload a clip, pick a target language, and the AI translates the dialogue, generates a natural voiceover, and re-syncs the speaker's lips to match the new audio. Whether you need to translate a video to English, Spanish, Hindi, Arabic or Mandarin, the workflow is the same: one upload, one click, one ready-to-publish dubbed video.
Unlike basic “translate video to text” tools, this is a true end-to-end AI video translator: it handles speech recognition, translation, multi-voice cloning and frame-accurate lip sync in a single pass. Multi-speaker scenes (up to 10 speakers) are separated automatically, and you can give the model a speaker count hint when you know it — handy for interviews, panels and podcasts where speaker overlap is common.
Dynamic duration matching keeps the pacing natural even when the translated language is longer or shorter than the source. Translating a punchy English line into Spanish? The model expands timing intelligently instead of crunching the audio. Going the other direction, it tightens delivery so the dub never feels forced. This is what separates a usable AI video translator from a mechanical one — and it's why creators use this model for YouTube channels, TikTok shorts, course lessons, sales demos and ad creative.
The regional dialect catalog is one of the deepest available: 14+ Arabic variants, 20+ Spanish locales, multiple Chinese (Mandarin, Cantonese, Wu) flavors, English in 15 territories, and full coverage of European, South Asian and African languages. If you want to translate a video into English with a UK accent, a US accent, or even an Indian English variant, you can pick the exact locale — not a generic “English” fallback.
Need an audio-only translation? Toggle the audio-only mode for podcasts, voiceovers or off-camera narration. The AI skips facial processing entirely, costs less, and finishes faster — usually in well under a minute. For on-camera footage, leave it off and the model will translate the video and re-render the speaker's mouth to match.
The AI Video Translator is paired with the rest of the JAI Portal localization stack — drop a translated clip into <a href="/jai-auto-subtitle-generator">Auto Subtitle Generator</a> for stylized captions, or send your master cut through <a href="/model/kling-o1-edit-video">Kling O1 Edit Video</a> for prompt-based re-edits before translating. If your content is image-led rather than video-led, the same engine quality is available for static localization workflows elsewhere on the platform.
Pricing is pay-as-you-go, billed per second of video — no subscription, no minimum, no platform fee. Most clips translate in 30–60 seconds. Output keeps your original resolution and aspect ratio, comes with full commercial-use rights, and is delivered as a standard MP4 ready for YouTube, TikTok, Instagram, LinkedIn or your CMS. After translation, send the dubbed cut through <a href="/model/ai-video-aspect-ratio-changer">AI Video Aspect Ratio Changer</a> if you need to reframe for vertical platforms, or <a href="/model/grok-imagine-extend-video">Grok Imagine Extend Video</a> if the localized version needs to be longer than the source.

⚠️ Considerations
△Heavy background music overlapping dialogue can confuse speaker separation — clean audio in first.
△Extreme close-ups may show very minor lip sync drift versus the Precision variant.
△Audio-only mode skips lip sync entirely, so don't use it for on-camera footage.
△Less common dialects have smaller training pools — main-tier languages are most accurate.

Frequently Asked Questions
It translates the spoken dialogue in your video into another language, generates a new voiceover in that language, and re-syncs the speaker's lip movements to match the dub. You upload a video, choose a target language, and get back a localized MP4. No subtitle workaround, no voice actor needed.
Upload your clip, set the output language to English — or pick a specific variant like English (UK), English (United States), English (India) — and hit generate. The same flow works for Spanish, Hindi, Arabic, Mandarin, French and 150+ more languages. Each generation outputs a single target language.
Yes — up to 10 speakers per clip. The AI separates voices automatically. If you already know the speaker count (e.g. a 2-person interview or a 4-person panel), set speaker_num as a hint between 1 and 10 to improve separation quality. Leave it empty for auto-detection.
Yes. The model re-renders the speaker's mouth to match the translated audio, so the final video looks natively spoken in the target language instead of dubbed-over. For polished captions on top of the dub, layer
Auto Subtitle Generator after translation.
Pricing is pay-as-you-go at $0.05 per second of source video. A 60-second clip translates for around $3 in credits. No subscription, no minimums — you only pay for what you translate.
Yes — enable “translate audio only”. It's the right pick for podcasts, voiceovers and off-camera narration where there's no on-screen speaker to lip-sync. It runs faster and costs less than full lip-sync mode.
Subtitles translate text on screen but leave the original audio untouched — your viewer still hears the source language. The AI Video Translator replaces the spoken audio with a translated voiceover and re-syncs the lips so the video plays natively in the target language. If you only need captions,
Auto Subtitle Generator is the right tool. If you need full dubbed video translation, this is the model. Many creators stack both: dub with this model, then add stylized subtitles on top.
Yes. All paid generations come with full commercial-use rights — YouTube monetization, paid ads, client deliverables, paid courses, product videos, internal training, anything. There's no separate license fee. You're responsible for having the rights to the source video you upload; the translation output itself is yours to use commercially.
Standard formats including MP4 (preferred), MOV and AVI either via direct upload or URL. Output preserves the source resolution and aspect ratio — 720p stays 720p, 1080p stays 1080p, vertical stays vertical. Typical translations finish in 30–60 seconds; longer or multi-speaker clips take proportionally longer. For very long-form content, split into segments and translate per segment for the cleanest result.
Each generation translates one source video into one target language. To localize across 5–10 markets, queue separate generations from the same upload — Spanish, French, Japanese, Arabic and so on. Because pricing is per-second and per-generation, you only pay for the languages you actually need, and you can prioritize your top markets first and expand as audience data comes in.
First check the source: clear facial visibility, even lighting, and clean audio (low background noise, minimal music) are required for accurate lip sync — the model needs to see and hear properly. Second, set the correct speaker count (1–10) instead of leaving it auto. Third, if the issue is the original recording rather than the translation, edit the source first with
Kling O1 Edit Video or
Wan VACE Video Edit, then re-translate. If you're still off after that, the source clip itself is likely the constraint (occluded mouth, profile shot, low resolution face).
⚖️ How AI Video Translator Compares
AI Video Translator is the everyday workhorse of JAI Portal's video translation lineup — fast enough for social-first creators, accurate enough for paid ad work, and priced per second of source video with no subscription. The combination of 150+ languages, deep regional dialect support, multi-speaker handling (up to 10 voices), dynamic duration matching and pay-as-you-go pricing makes it the default choice when you need to translate a video properly instead of just slapping subtitles on it. For lighter-weight workflows that only need captions on the source language,
Auto Subtitle Generator is the better fit — and the two stack beautifully (dub first, caption second) for TikTok, Reels and Shorts. To chain editing into the workflow, run the dubbed output through
Kling O1 Edit Video for prompt-based re-edits,
Wan VACE Video Edit for natural-language scene changes, or
Grok Imagine Extend Video when the localized cut needs to be longer than the source. If your master video needs cropping for vertical platforms,
AI Video Aspect Ratio Changer converts 16:9 → 9:16 / 1:1 / 4:5 cleanly without losing the subject. For upscaling a translated clip to 4K,
SeedVR2 Video Upscaler sharpens the final output before delivery.
