What is video localization?
Video localization refers to adapting and modifying a video's content, including dialogue, captions, graphics, and cultural references, to suit the linguistic, cultural, and regional preferences of a specific audience.
However, it's important to distinguish localization from translation.
Video localization does involve translating, dubbing, or subtitling the original video's audio into the target language, but that's not all. It also requires adjusting visual elements and ensuring that the overall message and context of the video resonate effectively with the intended viewers. Think images, colors, date and time formats, references, puns, idioms…
Multimedia localization plays a crucial role in expanding the global reach of videos, enhancing viewer engagement, and fostering cultural sensitivity and understanding.
Key aspects of video localization can include:
- Subtitling and dubbing: Subtitling involves providing written translations of the spoken content in the video, while dubbing replaces the original audio with a translated voiceover
- Transcription: This involves converting the video's audio into written text. This is typically the first step in subtitling and can also be helpful for creating closed captions for the hard of hearing
- Lip-syncing: Dubbing can sometimes involve lip-syncing, where the new voice track is matched as closely as possible to the lip movements of the original speakers
- Translation of on-screen text: Any text appearing in the video, such as signs, letters, subtitles, or infographics, must be translated
- Cultural adaptation: This involves modifying the content to suit the cultural context of the new audience. This could include changing references, humor, or images that may not be understood or could be offensive in the new culture
- Conversion of measures and formats: Things like currencies, dates, and measurements may need to be converted to formats familiar to the target audience
Why is video localization important?
Adapting video content for a new audience takes time and money. So why bother?
According to a report from the Harvard Business Review:
- 72.1% of consumers spend most or all of their time on websites in their own language
- 72.4% of consumers said they would be more likely to buy a product with information in their own language
- 56.2% of consumers said that the ability to obtain information in their own language is more important than price
Here are the specific benefits of video localization.
Enhanced audience engagement:
Localized videos resonate better with audiences by using their language and cultural nuances, increasing viewer retention and emotional connection.
Expanded reach:
Localization makes content accessible to non-native speakers and diverse audiences, expanding the reach of your message.
Higher conversion rates:
Localized content feels personalized, leading to greater customer trust and improved conversion rates for products or services.
Compliance with regional norms:
Ensures content adheres to local laws, cultural sensitivities, and ethical standards, reducing the risk of miscommunication or offense.
Competitive advantage:
Localized video content helps differentiate your brand from competitors who rely solely on generic or untranslated content.
Better ROI on content:
Repurposing existing video content through localization maximizes its value and impact without the need for entirely new production.
Increased SEO performance:
Localized content can boost search engine visibility in different regions, driving more organic traffic.
How to approach video localization
Understand your audience
Understanding your audience is key. Analyze your international markets, identify where engagement is strong, and prioritize localization efforts based on potential ROI. Start with basic research—you may uncover unexpected opportunities for localized content to thrive.
Decide what content to localize
Not all content needs immediate localization. Focus on content that delivers the most value. You might begin by adding subtitles or voiceovers to short videos and testing their impact in key markets before scaling. Experiment and refine your strategy as you go.
Choose the right tools or services
Once you’ve identified your target content and audiences, select tools and services to execute localization effectively. Look into options for video translation, subtitling and dubbing that match your goals. Below, we explore various localization methods to guide your choice.
Video localization methods
Subtitles:
Subtitles are a cost-effective way to localize video content, translating spoken dialogue into on-screen text without altering the audio. Tools like YouTube’s auto-captioning enable quick, automated subtitle creation in multiple languages, while open source manual tools like Aegisub offer precise customization but are time-consuming. Subtitles are ideal for reaching global audiences, testing new markets, and enhancing accessibility affordably.
Captions vs. Subtitles:
Captions and subtitles serve distinct purposes in video localization and accessibility.
Captions are designed to include both audio and visual cues, making them essential for viewers who are deaf or hard of hearing. They not only transcribe spoken dialogue but also describe non-speech elements like music, sound effects, and tone, ensuring the viewer fully understands the video’s context.
Subtitles focus solely on translating spoken content into another language for non-native speakers, without including audio cues. Subtitles are especially useful for localized video content and are widely used for muted social media videos or quick market testing, as they offer a cost-effective way to engage international audiences without requiring extensive re-editing or dubbing.
Voiceovers and Dubbing:
Voiceovers and Dubbing are two key methods for localizing video content, each serving different purposes.
Voiceovers involve overlaying a narrative-style translation onto the original video, making them an affordable and quick solution for localization. However, they often lack the emotional depth and tonal nuances of the original audio.
Dubbing replaces the original dialogue entirely, aligning the new voice track with on-screen lip movements to create a more immersive experience. While dubbing offers higher quality and emotional authenticity, it is typically more expensive and time-intensive.
Versioning
Versioning, also known as reversioning, is the process of adapting existing video content for a specific audience or region by modifying certain elements to improve relevance and engagement. Unlike full-scale re-creations or transcreation, versioning selectively updates parts of the content while preserving the core message and structure. This approach is cost-effective and efficient, making it a popular choice for marketing campaigns, training videos, and digital advertisements.
Transcreation
Transcreation reimagines content for a new audience while preserving the brand’s voice and intent. Unlike translation, it often starts from scratch and results in highly localized content tailored to specific cultural nuances. It's ideal for high-impact marketing campaigns and strategic branding efforts.
How to choose between subtitles, voiceovers, or dubbing
Start small: Subtitles are a cost-effective way to test new markets and assess audience engagement without a significant upfront investment.
Scale up: If your content gains traction, enhance the experience by investing in dubbing or voiceovers to create a more immersive and localized connection with your audience.
Use AI: Tools like Synthesia can automate translation and voice generation, offering a scalable, budget-friendly solution for dubbing or voiceovers while maintaining natural-sounding results.
