Mavericks Inc. Adds Eastern European and Balkan Languages to Video Generation AI "NoLang", Enabling In-House Production of Local Language Videos Without Translators or Narrators

Mavericks Inc. (Headquarters: Bunkyo-ku, Tokyo; Representative Director and President: Shota Okuno), the provider of the video generation AI "NoLang," has added "Croatian," "Bulgarian," "Ukrainian," and "Greek" – four Eastern European and Balkan languages – to NoLang's video generation capabilities. Users can simply select a language from the menu to generate videos with narration and subtitles in the local language directly from Japanese materials, with the duration automatically adjusted to match the speaking speed. This offers an efficient video production option for companies and municipalities looking to enhance tourism promotions or IR disclosures for Eastern Europe and the Balkans, without the need to arrange for translation companies or narrators.

Local Language Support Influences Purchasing Behavior, Cost Challenges for European-Expanding Companies

It is well-known that language barriers pose significant hurdles to purchasing and understanding when companies and municipalities aim to deliver information to consumers and customers overseas. A survey by CSA Research (formerly Common Sense Advisory) of 8,709 consumers in 29 countries found that 76% "prefer to buy products that provide information in their own language," and 40% "would not buy from a site that only offers content in other languages" (*1). This data underscores that local language content directly impacts information reach, comprehension, and calls to action. The importance of local language support remains unchanged when communicating with regions like Croatia, Bulgaria, Ukraine, and Greece in Eastern Europe and the Balkans.

Furthermore, cost burden is a common management challenge for Japanese companies expanding into Europe. The "FY2025 Survey of Japanese Companies Expanding Overseas (Europe Edition)" conducted by the Japan External Trade Organization (JETRO) (August 20-September 19, 2025, targeting 1,449 Japanese companies expanding into Europe, with 778 valid responses and a response rate of 53.7%) reported that companies expanding into Europe, including Eastern Europe, face numerous management challenges such as high cost structures and compliance with digital regulations (*2). In this context, even attempting to produce video content in-house for Croatia, Bulgaria, Ukraine, and Greece incurs significant time and cost for outsourcing to translation companies and recording narration. The challenge is that similar burdens arise each time a new language is added.

Against this backdrop, Mavericks, the provider of the video generation AI "NoLang," has made efforts to further expand its language support by newly enabling support for four languages in the Eastern European and Balkan regions.

"NoLang" Video Generation Now Supports 4 Eastern European and Balkan Languages, Generatable with a Single Button

With this latest update, "NoLang's" video generation function now supports four new languages: "Hrvatski (Croatian)," "Български (Bulgarian)," "Українська (Ukrainian)," and "Ελληνικά (Greek)." This marks the first time NoLang has offered support for languages in the Eastern European and Balkan regions.

The operation is extremely simple. By selecting one of the newly added Eastern European and Balkan languages from the "Language Settings" menu on the video generation screen, users can immediately create videos in their chosen language. This language selection menu is common across all video generation modes supported by NoLang, including text input, PDF materials, and audio files, allowing users to start producing videos for Eastern Europe and the Balkans without changing their existing workflow.

Generate Eastern European and Balkan Language Videos Simply by Uploading Japanese Materials

NoLang is a service that automatically generates videos with avatars explaining content from various input formats, including text input, questions, instructions, PDF documents, and audio/video files with audio. By selecting Croatian, Bulgarian, Ukrainian, or Greek as the output language, videos with local language scripts, narration, and subtitles can be generated directly from Japanese manuscripts or materials.

The newly added four Eastern European and Balkan languages are also supported in video generation modes such as "Presenting Materials," "Summarizing Materials," and "Analyzing Materials," which use PDFs as input. This enables the creation of explanatory, summary, or analytical videos that can be directly deployed for Eastern Europe and the Balkans simply by uploading existing Japanese documents like financial reports, product information, or lifestyle and administrative information.

Videos can be created simply by inputting PDFs.

Furthermore, for videos that have already been generated, they can be converted to Croatian, Bulgarian, Ukrainian, or Greek with a single click using the "Convert" button on the viewing screen. There is no need to recreate videos that were originally created in Japanese.

Videos in other languages can be converted with a single button.

Supports Latin and Cyrillic Scripts, Duration Automatically Adjusted to Speaking Speed

The subtitles (captions) displayed in the videos are rendered correctly without distortion using fonts that support the respective character sets: Latin/Greek for Croatian and Greek, and Cyrillic for Bulgarian and Ukrainian.

Additionally, NoLang is equipped with a mechanism that automatically calculates the narration playback time and estimated video duration based on the standard speaking pace for each language during video generation. This feature has also been extended to the newly added four Eastern European and Balkan languages. By adjusting the playback time based on differences in character count and word grouping for each language, it prevents unnatural pauses or overly fast speech, resulting in videos where narration and subtitles flow at a natural tempo.

Four Use Cases from Tourism Promotion to IR Disclosure

With the addition of these four Eastern European and Balkan languages, NoLang can now create videos directly applicable to specific use cases from existing Japanese materials.

First, multilingual promotional videos for inbound tourists. By simply inputting the text from existing tourism guides or brochures, promotional videos with narration and subtitles in Croatian, Bulgarian, Ukrainian, or Greek can be created. This allows for immediate engagement with potential tourists, especially for Greek-speaking travelers who have a high need for video information during their trip planning stages, without the need for outsourcing to translation companies or arranging narration recordings.

Second, multilingual dissemination of lifestyle and administrative information for foreign residents. By uploading administrative pamphlets or lifestyle guides from municipalities or companies, explanatory videos on lifestyle and administrative information in Croatian, Bulgarian, Ukrainian, or Greek can be generated directly. This is a use case with significant public benefit, making it easier for foreign residents in the community to access necessary information.

Third, disclosure of IR information to overseas investors. By simply uploading PDFs of financial reports or other documents created in Japanese and selecting Croatian, Bulgarian, Ukrainian, or Greek as the output language, explanatory videos for local investors can be completed.

Fourth, product introduction videos for cross-border e-commerce. By inputting text or materials summarizing product specifications and usage instructions, product introduction videos with local language narration and subtitles can be generated directly, ready for immediate deployment on e-commerce product pages or social media advertisements.

Future Outlook

Mavericks will continue to sequentially expand support for languages with high user demand and for the native languages of foreign communities rapidly gaining presence in Japan. As an "infrastructure for multilingual video production" centered on Japan and Asia, we will continue to support information dissemination that transcends language barriers.
