Accelerating Market Entry into Central and Eastern Europe, Rising Demand for Localized Content

Language barriers are widely recognized as a major obstacle to information reach and comprehension in overseas markets. According to a survey by CSA Research (Common Sense Advisory) of 8,709 consumers across 29 countries, 76% responded that they prefer to purchase products when information is provided in their native language, while 40% said they would not buy from websites available only in foreign languages (※2). Since Polish, Czech, Slovak, and Romanian each have unique linguistic systems distinct from English, delivering content in these local languages is directly linked to effective information penetration.

Additionally, JETRO's '2025 Survey on Japanese Companies Operating Overseas (Europe Edition)' (conducted from August 20 to September 19, 2025, targeting 1,449 Japanese companies operating in Europe, with 778 valid responses and a 53.7% response rate) revealed that base salary increases for companies entering Central and Eastern Europe have a median rise of over 4%. Furthermore, among manufacturers, the proportion of companies anticipating improved operating profits increased by 10.6 percentage points year-on-year, reaching 44.7% (※3), indicating steadily growing business activities in the region.

Video-based communication is gaining attention as an intuitive way to overcome language barriers and convey messages effectively in these increasingly active local markets. However, the recurring need to outsource translation and voice recording for video localization imposes significant time and cost burdens. Against this backdrop, Mavericks, the developer of the AI video generation tool 'NoLang', has expanded its supported languages.

NoLang Now Supports Four Central European Languages—Generate with One Click

This update adds four new languages to NoLang's video generation functionality: 'Polski (Polish)', 'Čeština (Czech)', 'Slovenčina (Slovak)', and 'Română (Romanian)'.

Generating videos is simple. From the 'Language Settings' menu in the video creation interface, users can select any of the newly added Central European languages. The system will then directly output an avatar video in the selected language. This language selection menu is available across all NoLang video generation modes—including text input, PDF documents, and audio files—allowing immediate production of Central European market videos without altering existing workflows.

Upload Japanese Documents to Instantly Create Central European Language Videos

NoLang is a service that automatically generates explanatory videos featuring avatars from various input formats, including text input, questions, instructions, PDF documents, audio, and video files with audio. By selecting Polish, Czech, Slovak, or Romanian as the output language, users can generate videos complete with localized scripts, narration, and subtitles directly from Japanese source materials.

The newly added Central European languages are now supported in all PDF-based video generation modes, such as 'Present the Document', 'Summarize the Document', and 'Analyze the Document'. This enables users to upload existing Japanese documents—such as financial reports or product specifications—and instantly create explanatory, summary, or analytical videos ready for deployment in Central European markets.

Video completed simply by uploading a PDF

Moreover, for videos already generated, a one-click language conversion to Polish, Czech, Slovak, or Romanian is possible via the 'Convert' button on the viewing screen. With a simple operation—just selecting the target language—there is no need to recreate videos from scratch. Japanese videos previously created on NoLang can be directly converted into versions for Central European audiences.

Accurate Subtitle Display and Automatic Duration Adjustment Based on Language Characteristics

Subtitles (captions) displayed in videos now use fonts optimized for Latin script representations of Polish, Czech, Slovak, and Romanian. This ensures accurate rendering without distortion, even for language-specific special characters such as ł and ż in Polish, č, š, and ř in Czech and Slovak, and ă and ț in Romanian.

Furthermore, NoLang features an automatic timing adjustment mechanism that calculates narration playback time and video duration based on each language’s standard speaking pace (characters per minute). This functionality has now been extended to Polish, Czech, Slovak, and Romanian. By accounting for differences in character count and word grouping across languages, NoLang prevents unnatural pauses or rushed speech, ensuring that narration and subtitles flow at a natural, synchronized pace.

Expanding Use Cases Across Central Europe—from Manufacturing Training to Cross-Border E-Commerce

With support for these four Central European languages, the range of videos that can be directly created on NoLang has significantly expanded. The ability to strengthen communication with local employees and business partners in Central Europe—while reducing the time and cost associated with outsourcing translation and voice recording—offers a practical solution to the dual challenges of talent acquisition and cost management. Specifically, NoLang can be utilized in the following scenarios targeting the Polish, Czech, Slovak, and Romanian markets.
