When video content crosses a language border, you have three main options: dubbing, voiceover and subtitles. Each one changes how the audience experiences your content, how much the project costs and how fast it can be delivered. Choosing the right method is one of the most important decisions in video localisation.
Key takeaways
- Lip-sync dubbing gives the most immersive experience but takes the most time and budget.
- Voice-over translation is faster and more affordable, and works well for documentaries, interviews and corporate video.
- Subtitles are the most economical and keep the original performance, but demand attention from the viewer.
What is dubbing?
In lip-sync dubbing, the original dialogue is fully replaced with a new recording in the target language. Translators adapt the script so that the new lines match the length, rhythm and lip movements on screen, and voice actors perform each character in the studio.
Best for: animation, children’s content, feature films and series, games and premium commercials where the audience should forget the content was ever in another language.
What is voiceover (voice-over translation)?
In voice-over translation, the translated voice is placed over the original audio, which remains audible at a lower volume. The new voice usually starts a moment after the original speaker. There is no attempt at exact lip-sync.
This approach has a long tradition in Georgian and other post-Soviet broadcasting, where films and series have often been shown with one or several voices reading the translation over the original soundtrack. Today it is widely used for:
- documentaries and reportage,
- interviews and testimonial videos,
- corporate, training and product videos.
Best for: factual and informational content where authenticity matters and the original speaker should still be heard.
What are subtitles?
Subtitles display the translated dialogue as text on screen while the original audio stays untouched. They are fast to produce and easy to update, and they also improve accessibility and viewing with the sound off — a common habit on social media.
Best for: social media video, festivals, content for audiences used to reading subtitles, and projects with tight budgets or deadlines.
Side-by-side comparison
| Lip-sync dubbing | Voice-over translation | Subtitles | |
|---|---|---|---|
| Audience experience | Most immersive | Natural, authentic | Requires reading |
| Original voice audible | No | Yes, in the background | Yes |
| Production time | Longest | Medium | Shortest |
| Relative cost | Highest | Medium | Lowest |
| Works for children / low-literacy audiences | Yes | Yes | Limited |
| Easy to update later | Hard | Moderate | Easy |
How to choose: five questions
- Who is the audience? Young children and audiences who prefer not to read need audio — dubbing or voiceover.
- What is the content? Drama and animation benefit from dubbing; factual content suits voiceover; short social clips suit subtitles.
- Where will it be watched? On social feeds, many people watch without sound, so subtitles (or both subtitles and voice) work better.
- What are the budget and deadline? If both are tight, subtitles or a single-voice voiceover are realistic.
- How long will the content live? Evergreen training libraries and brand films justify a bigger upfront investment.
Combining methods
You do not have to choose only one. Many brands use a voiceover for the main version and subtitles for social cut-downs, or dub hero content while subtitling supporting videos. The key is consistency: use the same terminology, brand voice and, where possible, the same voice actors across the campaign.

Quality tips for localisation
- Adapt, do not just translate. Spoken language needs shorter sentences and natural phrasing; see how to prepare a voiceover script.
- Check timing early. Georgian and English texts differ in length, so translated lines must still fit the picture.
- Provide a pronunciation guide for names, brands and terms.
- Ask for separated audio tracks (dialogue, music, effects) from your video editor — it makes dubbing and voiceover mixing much cleaner.
- Budget for review by a native speaker before final mixing. For cost drivers, see our voiceover pricing guide.
The right localisation method is the one your audience barely notices: they simply understand, trust and remember your message.
