Newgia Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative Director: Kashiwaguchi Yukihiro) announced today, April 29, 2026, the new implementation and integration of the globally recognized, cutting-edge video generation AIs "HappyHorse 1.0 (Alibaba-affiliated)" and "Seedance 2.0 (ByteDance-affiliated)" into its AI video production platform "genas.ai."

AI video production platform "genas.ai": https://genas.ai
This update structurally resolves the biggest challenge in video production: the "quality and delivery risk due to single-engine dependency."
By making the latest overseas high-end AI models available in a complete domestic practical environment with a Japanese UI and JPY payment, it brings dramatic efficiency improvements and enhanced expressive power to the video production process for Japanese creators.
■ "Invisible Failure Risks" and Engine Limitations in AI Video Production
While AI video generation technology is rapidly spreading, practical challenges are already emerging in professional video production.
Output variability due to engine characteristics:
Even with the same prompt (instruction), the results vary significantly depending on the generation engine used.
Generation instability:
Probabilistic occurrences such as character model collapse, unnatural motion, and unintended camera work failures occur.
Correction and delivery delay loop:
Creators often have to repeat "gacha (regeneration)" until the desired video is output, which increases correction costs and puts pressure on delivery times.
AI video generation is a probabilistic technology. Therefore, the essence of the problem in modern video production has completely shifted from "whether to use AI" to "how to compare multiple engines and select the optimal one for the project."
■ Why "HappyHorse 1.0" and "Seedance 2.0" now?
Currently, in the global AI video generation domain, fierce competition is taking place based on advanced evaluation axes such as naturalness of motion, camera work control, composition/direction capabilities, character consistency, and "simultaneous generation of video and audio (lip-sync, etc.)."
Among them, the two engines implemented this time are dominating the industry as the core of next-generation video production.
1. HappyHorse 1.0: A Dark Horse with "Overwhelming Expressive Power" that Suddenly Rose to World No. 1
HappyHorse 1.0
Developed by Alibaba's research team (ATH), this ultra-high-performance model suddenly ranked first (top Elo score) in April 2026 on the third-party AI model evaluation platform "Artificial Analysis" Video Arena, surpassing renowned competitors (*1).
Cinematic composition and direction:
Excels in multi-shot storytelling with cinematic quality and complex transitions.
Perfect lip-sync and audio integration:
Can co-generate video and multilingual audio in a single pass, demonstrating powerful capabilities for global content.
2. Seedance 2.0: "Ultimate Stability and Consistency" for Practical Use
Seedance 2.0
Provided by ByteDance, this is a next-generation model that supports multimodal input (text, images, videos, audio).
Character and scene consistency:
Highly acclaimed for its ability to maintain the details of specified characters and products without degradation across different shots and angles.
Advanced camera work control:
Accurately reproduces precise camera movements required in live-action video production, such as pan-outs and orbits, from prompts and reference videos.
■ [Most Important] Breaking the Barrier of "Knowing but Unable to Use" in Japanese Production Sites
While these world-class models are of great interest to video creators, there are extremely high hurdles for Japanese production companies to practically introduce them as corporations.
English-only user interface
Only foreign currency payment (USD-denominated credit card) supported
Necessity of development capabilities and environment setup based on complex API connections
Absence of Japanese customer support
As a result, Japanese video production sites faced a significant opportunity loss, "knowing the latest AI technology but unable to use it due to incompatibility with their own production workflow or payment rules."
The greatest value of "genas.ai" lies in completely eliminating this barrier.
All-in-one
Through "genas.ai," these cutting-edge engines can be used immediately in the following environment:
