Singapore-based AI video generation startup Video Rebirth has raised $50 million in fresh funding to develop what it describes as a “world model” designed specifically for professional film, advertising, and animation studios.
The round drew participation from a mix of global financial and strategic backers, the company said, without naming the investors or disclosing its valuation.
The raise will be used largely to scale compute, model training, and product rollout as the startup prepares to launch its first commercial version in December 2025.
Founded by Dr. Wei Liu, a former Tencent Distinguished Scientist and IEEE/AAAS Fellow, Video Rebirth is looking to differentiate itself through video models that prioritises physical realism and fine-grained control.
“Video generation is the most direct pathway to building interactive world models, but the industry’s scaling laws are not yet solved,” said Liu.
“Our mission is to move beyond simple ‘text-to-video’ tools and build a true generative platform. We are engineering for the creators who need cinematic quality and physical consistency, not just novelty. This funding allows us to accelerate our research and build an ecosystem for the next AI Generated Entertainment (AIGE) trend,” he added.
The company’s core technology, which it calls ‘Physics Native Attention’, underpins its ‘Bach’ video model series. The system is built to keep motion, lighting, and object interactions consistent with real-world physics, resulting in more realistic shadows, movement, and scene continuity. These are features that professional filmmakers and advertisers typically require, but which most current AI video models still struggle to deliver, according to Video Rebirth.
Globally, generative video has become one of the fastest-growing segments in AI, led by companies such as Runway, Pika Labs, and Synthesia, all of which have attracted significant investor interest recently.
US-based Runway raised $308 million in April, while UK-based Synthesia secured $180 million in January. In June last year, US-based Pika Labs also raised $80 million.
The deal comes amid a modest rebound in software and IT startup funding in Southeast Asia.
According to DealStreetAsia’s Southeast Asia Deal Review for Q3 2025, the sector logged eight equity deals totalling $10.8 million, up from five in each of the previous two quarters. That brought total funding for the first nine months of the year to $49 million.
