Mavericks, Inc., the company behind NoLang, Japan’s largest AI video generation service, has released a new feature that converts a finished video between horizontal (16:9) and vertical (9:16) formats and regenerates it with a single click. The feature is aimed at companies that need to move faster on social media marketing and multi-platform distribution.
With this release, a horizontal video for YouTube or a website and a vertical short video for TikTok, Instagram Reels or YouTube Shorts can be produced at the same time from a single source, such as a piece of text or a document. It removes the editing work of rebuilding layout and structure for each platform, so one round of content production can immediately serve every channel.

NoLang is an AI video generation service that produces a video in as little as a few seconds from text, a PDF or PPTX document, a website URL, or an image, audio or video file. According to Mavericks, Inc., it was the first service of its kind in Japan. Since its release in July 2024 it has passed 150,000 registered users and has been adopted by more than 60 companies, making it one of the largest generative AI products to come out of Japan (as of December 2025).
Vertical short video on TikTok and Instagram Reels has become as essential to corporate marketing as video platforms such as YouTube. But simply cropping a horizontal video cuts off captions and pushes the subject out of position, so each platform needs its own optimized version. Securing the cost and the people for that work has been a significant obstacle, and companies short on resources have often distributed to only one platform and missed the chance to reach potential customers elsewhere.
This update lets users convert the aspect ratio of a video generated in NoLang and regenerate it with a single click. What matters is that this is not simple cropping: the AI rebuilds the layout for the selected aspect ratio (16:9 or 9:16), repositioning the avatar and adjusting subtitle size, line breaks and the display area for background documents.
As a result, a multi-channel approach — a detailed explanation on YouTube as a horizontal video, a focused announcement on TikTok as a vertical one — can be executed immediately, with no extra editing.
How to convert horizontal and vertical videos instantly in NoLang
The whole process runs in the browser, with no specialist video editing software.
Steps
- Create a video with the Generate from text feature in NoLang (you can start from either horizontal or vertical).
- On the video viewing screen, select the button for changing aspect ratio and language.
- Choose the ratio you want (16:9 or 9:16).
- Press Generate, and an alternate version of the video is created automatically with an optimized layout.
Practical scenarios and their benefits
1. Produce website and social video from one owned-media article, doubling traffic routes at no extra production cost
Until now, even after creating a horizontal video to embed in a website article based on a blog post or press release, expanding to vertical platforms such as TikTok or YouTube Shorts meant rebuilding the video from scratch because of the different aspect ratio. With NoLang, entering the content of the article produces the horizontal video for the website, and one click converts it into a vertical video ready for social media. Companies get both the longer time on page that an embedded video brings (an SEO benefit) and the awareness and traffic that short video brings from social platforms, without extra cost or editing time, maximizing content reach and site visits.
2. Turn recruiting information into social video, and raise application rates with company overview videos on social media
In new-graduate recruiting, candidates gather information from Instagram and TikTok as well as from company websites. Existing company overview materials (PDF and PPTX) are usually built in landscape, and reworking them into vertical video is expensive, so social distribution tends to be left undone. With the NoLang conversion feature, a horizontal video made for an online information session becomes a vertical short video for social media in moments. The AI adjusts text size and avatar placement automatically for legibility on a phone screen, which keeps students who watch mainly on mobile from dropping off and strengthens the path from awareness to application. Recruiting can run on both the careers site and social media with the resources already in place.
3. Repurpose e-commerce product videos as social ads to widen the path to purchase and improve ROAS
Product introductions on e-commerce sites and landing pages are mostly horizontal video designed for desktop viewing, but social ads on Instagram and TikTok, where high-intent buyers gather, require vertical video. With NoLang, a detailed explainer video made for a product page can be converted in an instant into a vertical ad video that stands out in social feeds and stories. Presenting products in the format best suited to each platform speeds up the PDCA cycle of creative production and contributes to better ad performance and sales.
What comes next
Mavericks, Inc. will continue developing features that make NoLang more expressive and more practical. Alongside this aspect ratio conversion, the company plans to strengthen functions such as automatic adjustment of video length to match platform trends and structural suggestions based on engagement analysis per social platform, developing NoLang into a platform that supports corporate video marketing at the level of infrastructure.
