Video Rebirth

What Video Rebirth does

Video Rebirth is a Singapore-headquartered AI startup founded in late 2024 by Dr. Wei Liu, a former Tencent Distinguished Scientist who previously led development of Tencent's flagship AI model. The company's core product is BACH, an industrial-grade AI video engine publicly launched in May 2026 that generates cinematic multi-shot videos up to 30 seconds with character consistency and emotional continuity at Native 30fps and 1080p resolution. BACH is built on three proprietary technical components: Physics-Native Attention (PNA) for spatio-temporal character consistency, Dual Diffusion Transformer (Dual DiT) for prompt adherence at Native 1080p, and a Multi-Step Sampling Loss training technique that the company claims delivers substantially lower inference costs than comparable frontier models.

BACH targets four primary enterprise verticals—film and cinema production, advertising agencies, e-commerce platforms, and game studios—with secondary reach into professional content creators and independent/emerging filmmakers. Revenue is generated through a combination of direct enterprise sales ([email protected]), self-serve platform access at www.bach.art (launched May 2026), and strategic channel partnerships such as the Digital Creator Africa Academy (DCAA) agreement announced at Cannes in May 2026. Pricing is quote-based and not publicly disclosed. The company has raised $80 million in seed-stage funding across a November 2025 initial close and a March 2026 extension, with strategic backers spanning semiconductors (AMD Ventures), automotive (Hyundai Motor Group), entertainment (CJ Group/HIVEN, Actoz Soft), and venture capital (Qiming Venture Partners, Openspace Capital, Gaw Capital).

At public launch BACH ranked #6 globally on the Artificial Analysis Video Arena benchmark—the highest-ranking startup model in the top 10 alongside Alibaba, ByteDance, and xAI. Video Rebirth is headquartered in Singapore with additional offices in Hong Kong and the United States, and has disclosed a roadmap for an Olympus world model targeted at end of 2026 aimed at simulating physical reality in real-time.

Core offering

Video Rebirth develops and operates BACH, an industrial-grade AI video generation engine that interprets professional creative intent across character identity, emotional performance, camera language, and narrative structure to produce cinematic multi-shot videos up to 30 seconds with character consistency and emotional continuity. The engine combines proprietary Physics-Native Attention (PNA), a Dual Diffusion Transformer (Dual DiT), and a Multi-Step Sampling Loss technique to deliver Native 30fps, 1080p output, and is publicly available at www.bach.art alongside enterprise APIs.

Product overview

Video Rebirth operates a unified product portfolio anchored by BACH, its publicly available industrial-grade AI video engine (launched May 2026) accessible at www.bach.art, with a planned world model codenamed Olympus targeted for end of 2026. The portfolio is powered by three proprietary technologies embedded inside the BACH engine: Physics-Native Attention (PNA) for spatio-temporal character consistency, the Dual Diffusion Transformer (Dual DiT) architecture for prompt adherence at Native 1080p, and a proprietary Multi-Step Sampling Loss technique that enables Native 30fps generation at reduced inference cost. Together, these constitute Video Rebirth's "Industrial-grade AI Engine" positioning — bridging imagination and production for professional creators across film, advertising, animation, e-commerce, and gaming — with Olympus intended to extend the platform from video generation into real-time physical world simulation.

Direct peers

• Runway: Runway is a direct peer in AI video generation, offering text-to-video and image-to-video models (Gen-3/Gen-4) targeted at professional creators in film, advertising, and media — the same buyer segments BACH pursues, with a comparable SaaS + enterprise go-to-market.
• Pika Labs: Pika is a direct peer in consumer-and-pro AI video generation, with model launches benchmarked on the same Artificial Analysis leaderboard as BACH and a similar prosumer/creator user base.
• Luma AI: Luma AI develops generative video and 'world models' (Ray, Dream Machine) that compete head-to-head with BACH on quality, length, and cinematic control — and the company's world-model roadmap overlaps with Video Rebirth's announced Olympus product.
• Kling (Kuaishou): Kling is Kuaishou's flagship text-to-video model, ranked alongside BACH in the Artificial Analysis top 10, with rapid iteration on frame rate, duration, and cinematic quality that puts it in direct competition for the same professional creator workflows.
• Wan (Alibaba): Alibaba's Wan video model is a top-ranked direct competitor in generative video, sharing the Artificial Analysis leaderboard with BACH and targeting similar cinematic and advertising use cases with much larger distribution and compute resources.
• Stability AI: Stability AI is a direct peer in open and commercial generative media models, with Stable Video and related video diffusion models that compete with BACH in the same creator and studio segments.

Broad incumbents

• OpenAI Sora: OpenAI's Sora is a broad incumbent in AI video generation, offering a frontier text-to-video product as part of a much larger general-purpose AI portfolio. While not specialized in BACH's 'industrial-grade' positioning, Sora's distribution, brand, and capital set the competitive ceiling in this category.
• Google Veo: Google's Veo model is a broad-incumbent AI video generator bundled into Google Cloud and creative tools, competing with BACH for enterprise media and advertising workflows with the backing of Google's compute and distribution.

Emerging players

• Synthesia: Synthesia is an emerging player in AI-generated video focused on enterprise avatars and corporate communications — adjacent rather than directly overlapping with BACH, but competing for the same advertising and corporate content budgets.
• HeyGen: HeyGen is an emerging player in AI video generation for marketing and localization, sharing BACH's enterprise advertising and e-commerce customer segment while specializing in avatar-led video rather than cinematic generation.
