Think about times you’ve watched a foreign video where subtitles are off, or the humor doesn’t make sense. 

That’s where video localization comes in.

In this article, you’ll learn how to do culturally relevant translation and follow proven strategies to localize your videos.

What is Video Localization (Compared to Video Translation)?

When localizing a video, you’re doing more than just translating the language. 

Video localization adapt not just the language but also the imagery, symbols, and tone of your content. You’re making sure that everything from the humor to the color choices aligns with the preferences of your target audience. 

Let’s say your original video is for a U.S. audience and uses jokes or idioms that make sense there. When localizing for an audience in Japan, you’d adapt or replace those jokes to better match local humor. The same goes for symbols or cultural references that might not be understood globally.

Localization also often involves editing the timing of your video, especially if you’re dubbing it. The pace of speech can differ between languages, so you may need to adjust scenes to match new voiceovers. 

If you’re using video translation, you’re simply taking the text or speech from your video and converting it into another language. For example, if your video is in English and you add Spanish subtitles, that’s a translation. This is a fast and effective solution for making your content understandable to a wider audience. However, translation doesn’t always consider cultural differences. 

Tools for Video Localization: Subtitles vs. Dubbing

When you localize a video, you have two main options to consider: subtitles or dubbing. Each has its strengths, and the right choice depends on your budget, the type of content, and your target audience’s preferences.

Subtitles 

Subtitles are a popular option because they’re cost-effective and relatively easy to implement. 

If you want to reach international audiences without spending too much, adding subtitles in different languages is a quick way to make your content accessible. 

Subtitles are also the preferred option for content where authenticity matters. For example, in documentaries or educational videos, it’s often better to let the original speaker’s voice remain while offering viewers a translation in their language.

Dubbing 

Dubbing, on the other hand, involves replacing the original audio with a voiceover in the target language. This option is more expensive than subtitling, but it provides a smoother, more immersive experience for viewers, especially for entertainment content like movies or TV shows. 

With dubbing, the audience doesn’t need to read along with the action, which makes the content more accessible and enjoyable​.

Best Practices for Video Localization

True localization goes beyond language—it requires cultural insight, attention to detail, and an understanding of your audience’s viewing habits. Below are my top recommendations for video localization that elevate your content :

1. Prioritize Cultural Relevance Over Direct Translation 

You can’t simply translate words and expect the same emotional response from your new audience. Successful localization adapts everything—language, visuals, and even humor—to the cultural preferences of the target market. 

For instance, a joke that lands in the U.S. could fall flat in Japan or even be offensive. You need to ensure that your content aligns with the values and norms of your viewers.

2. Skip Machine Translation for Critical Projects 

Let’s be honest—AI translation has come a long way, but it’s still not enough for high-stakes content. 

Tools like Google Translate or basic AI-driven platforms might give you a rough draft, but without human oversight, the nuances of meaning, tone, and context get lost. 

You need a native-speaking translator who understands both the language and the cultural subtleties. 

3. Aim for Consistency in Branding Across Languages 

One of the most overlooked aspects of localization is maintaining consistency across all versions of your video. 

Your core message, branding, and tone need to stay the same, whether your video is in English, Spanish, or Mandarin. Inconsistent translations or mismatched branding can dilute your identity and confuse your audience. 

4. Synchronization is Non-Negotiable 

Whether you’re using subtitles or dubbing, proper timing is crucial. Nothing pulls a viewer out of the experience faster than misaligned subtitles or poorly synced voiceovers. 

If your subtitles lag behind the dialogue or if dubbed audio doesn’t match lip movements, you risk losing credibility. 

5. Don’t Skip the Final Review 

Here’s something that too many companies overlook—testing. Once your video is localized, you need to review it with native speakers from the target region. 

Even the best translators can make mistakes, and what seems fine in theory might not resonate in practice. Conduct user testing with a small audience before launching the final product to catch any awkward phrasing or cultural missteps. 

Using AI Tools for Subtitles and Dubbing

AI has completely changed the landscape of video localization. If you’re still relying on manual subtitling or dubbing processes, you’re missing out on huge efficiency gains : 

AI for Subtitles

AI-driven subtitle tools are a game changer. They allow you to automatically generate subtitles in multiple languages, cutting down the time it takes to transcribe and translate videos. AI tools like Checksub can transcribe the audio, translate it into over 100 languages, and synchronize subtitles to the spoken dialogue—all in a fraction of the time it would take manually​. 

AI for Dubbing

AI-powered dubbing is even more impressive. In the past, dubbing was expensive and time-consuming, requiring voice actors for every language version of your video. But now, AI dubbing tools like Checksub can create realistic voiceovers in multiple languages, with lip-syncing technology that matches the audio to the video.
