Singapore-based AI video generation startup Video Rebirth has raised $50 million in new funding to develop what it calls a “world model” designed specifically for professional film, advertising and animation studios.
The company said the round attracted participation from financial and strategic backers around the world, but did not disclose the names of the investors or their valuations.
The funding will primarily be used to scale up compute, model training, and product deployment as the startup prepares to launch its first commercial version in December 2025.
Founded by former Dr. Wei Liu. tencent special scientist IEEE/AAAS Fellow Video Rebirth differentiates itself through a video model that prioritizes physical realism and fine-grained control.
“Video generation is the most direct means to build interactive world models, but the industry’s scaling laws have not yet been solved,” said Liu.
“Our mission is to move beyond simple ‘text-to-video’ tools and build a true generation platform. We engineer for creators who need not just novelty, but cinematic quality and physical consistency. This funding will allow us to accelerate our research and build an ecosystem for the next AI Generated Entertainment (AIGE) trend,” he added.
The company’s core technology, called “Physics Native Attendance,” powers the “Bach” video model series. The system is built to match motion, lighting, and object interactions with real-world physics, resulting in more realistic shadows, movement, and scene continuity. According to Video Rebirth, these are features that professional filmmakers and advertisers typically need, but are still difficult to achieve with most current AI video models.
Globally, generative video has become one of the fastest growing areas in the AI space, led by companies like Runway, Pika Labs, and Synthesia, all of which have recently attracted significant investor interest.
US-based Runway raised $308 million in April, while UK-based Synthesia secured $180 million in January. Last June, US-based Pika Labs also raised $80 million.
The deal comes amid a modest recovery in funding for software and IT startups in Southeast Asia.
According to DealStreetAsia’s Southeast Asia Deal Review for Q3 2025the sector recorded eight stock transactions totaling $10.8 million, up from five in each of the past two quarters. This brings our total funding in the first nine months of this year to $49 million.
