Subtitles preserve the original voice
They are faster and easier to edit, but viewers must read and timing still needs review.
Localization workflow planner

Subtitles preserve the original voice
Video translation workflow planner
This planner does not pretend to translate a file. It creates a review checklist you can use to evaluate a dedicated translation provider.
Dubbing changes the audio performance
Voice matching, pronunciation, pacing, multiple speakers, and disclosure become part of the job.
Lip sync is a separate transformation
It can improve visual alignment but adds identity, consent, distortion, and timing risks.
A reliable AI video translation workflow
Transcribe the source
Create speaker-aware, timestamped text and correct names, numbers, acronyms, and domain terms.
Translate for the locale
Adapt meaning, tone, reading speed, and cultural context rather than translating word for word.
Choose voice and lip sync
Use subtitles, stock voices, authorized voice cloning, or lip sync only when the audience and consent justify it.
Human-review every version
Check terminology, speaker assignment, pronunciation, timing, captions, on-screen text, claims, and accessibility.
Export and verify
Confirm MP4, SRT, VTT, transcript, audio tracks, duration, player behavior, and one version per locale.
Subtitles vs dubbing vs lip sync
| Output | Best when | Review burden |
|---|---|---|
| Translated subtitles | Speed, accuracy control, accessibility, original performance | Reading speed, line breaks, timing, speaker labels |
| AI dubbing | Hands-free viewing and market reach | Voice, pronunciation, emotion, duration, consent |
| Dubbing + lip sync | Visible speakers and high-polish localization | All dubbing checks plus facial distortion and identity risk |
| Transcript translation | Review, documentation, or downstream recording | Terminology, context, speaker attribution, timestamps |
Vidloop does not currently translate existing videos
The page is an honest planning and evaluation aid. It does not expose a fake upload box or send media to a hidden translation service.
- Use a dedicated translator for existing-video subtitles, dubbing, and lip sync.
- Never clone a voice or alter a visible speaker without appropriate rights and consent.
- Machine translation needs review for names, numbers, claims, safety, humor, and cultural context.
- Vidloop can generate a fresh localized visual after an approved script, but that is not translation of the original footage.
Video translation AI FAQ
What is the difference between subtitles and dubbing?
Subtitles translate text while preserving the original audio. Dubbing replaces or overlays speech in the target language and adds voice, pronunciation, timing, and consent decisions.
Do I need lip sync?
Only when a visible speaker and the target experience justify the extra processing. Training, podcasts, and many social videos may work well with accurate subtitles or voiceover.
Can AI translation be published without review?
No. Review names, numbers, terminology, claims, timing, speaker assignment, culture, accessibility, and legal requirements in every target locale.
Can Vidloop translate my uploaded video?
Not currently. Vidloop generates new video shots; this page helps plan and evaluate a separate localization workflow.
