In the global generative AI wave, text-to-video has become one of the most fiercely competitive fields. In early 2024, OpenAI's Sora broke through limitations in video length and logical consistency, marking an inflection point in technology. Models based on the Diffusion Transformer (DiT) architecture can now generate up to 60-second HD videos with 89% temporal consistency—far exceeding the 3-second limit of earlier models. This technological breakthrough ignited the market, with o

verseas unicorns Runway and Luma AI racing for massive funding rounds: Runway sought $500 million at a $5 billion valuation, while Luma AI reached a $3.2 billion valuation targeting up to $1.1 billion in funding. Meanwhile, Chinese vendors like Kuaishou Kling and ByteDance dominate performance benchmarks and see explosive commercial growth, forming a "dual-polar structure" in the global video generation landscape.
I. Global Vendor Competition: Tech Race & Market Positioning
Overseas Camp: Dominated by Hollywood & Professional Creators
Runway: Valuation >$5B, deeply integrated with Hollywood film production. Provides AI video tools to Lionsgate and AMC Networks, used in multiple movie VFX. Despite a $155M net loss in 2024 ($44M revenue), investor confidence in its tech moat remains high.
Luma AI: $3.2B valuation, focused on creator ecosystems serving artists/ad agencies. Monetizes rapidly via Dream Machine model—valuation surged ~12x in one year.
Tech Giants: Google Veo3 supports 60s generation; OpenAI Sora gradually opens enterprise testing; Meta explores acquisitions.
Chinese Camp: Dual Strategy of Short-Video Ecosystem & Global Expansion
Kuaishou Kling: Top 5 globally on AGI-Eval benchmark. Q1 2025 revenue >¥150M, >60% from overseas. Tech highlight: Version 2.1 auto-matches sound effects, serving Japanese/Korean/European enterprises.
ByteDance: Seedance model ranks #1 globally for text-to-video; Conch model leads in image-to-video. Leverages Douyin ecosystem for "creation-distribution" closed loop.
Startups: MiniMax’s Conch and PixaVerse target global markets—the latter has >60M users; ShengShu Tech’s Vidu focuses on B2B, partnering with Feishu and Baidu Search.
*Table: Core Metrics of Leading Global Text-to-Video Vendors (2025)*
| Vendor | Flagship Model | Valuation | Core Technical Edge | Primary Market |
|---|
| Runway | Gen-3 | $5B | Cinematic lighting rendering | Hollywood film/TV |
| Luma AI | Dream Machine | $3.2B | Dynamic detail control | Creator platforms |
| Kuaishou Kling | Kling 2.1 | N/A | Audio-visual synchronization | East Asia/Europe |
| ByteDance | Seedance | N/A | Long-context storytelling | Douyin ecosystem/global |
| OpenAI | Sora | N/A | Physics simulation consistency | Enterprise clients |
II. Technology Evolution: From Architecture Innovation to Multimodal Fusion
DiT Architecture Becomes Industry Standard
OpenAI’s Sora validated Diffusion Transformers, with its spatiotemporal joint attention mechanism solving frame-skipping issues in traditional U-Net architectures. Major vendors quickly followed—Runway Gen-3 and Kling adopted DiT variants supporting 720p-1080p resolution and 5-10s generation.
Vertical Optimization Drives Differentiation
Film Industry: Runway developed frame-level precision tools for editing needs.
Short Video: ByteDance’s JiMeng boosted templated generation efficiency by 50% (<5s rendering), fitting Douyin’s fast-paced production.
Open Source: Alibaba’s Tongyi Wanxiang WAN 2.2 open-sourced MoE architecture—saving 50% compute costs—with fine controls for lighting/focus.
Multimodal Fusion: The Future Direction
Google Gemini and DeepSeek Janus-Pro pioneer unified text-image-video-audio architectures. Kling’s Orthus model enables cross-modal understanding, supporting video editing products. The goal: end-to-end generation (input script → finished video), slashing professional production barriers.
III. Business Model Diversification: Mass Subscription vs. High-Value Services
Subscription Dominates Consumer Market
Tiered Pricing: Kling offers $10/$37/$92 tiers; Conch uses "free credits + token packs" with >8% user pay rate.
Cost Optimization: Alibaba’s MoE and Kling’s inference-side breakeven push prices down to $0.011/sec (standard mode)—within creators’ price-insensitive range.
B2B Focuses on High-Value Scenarios
Runway’s custom VFX for AMC shows earns millions per project.
ShengShu Vidu integrates with Feishu meetings for auto-generated marketing videos (>70% renewal rate).
Cost Revolution: Disney’s animation costs dropped from $2M/min to $300/min with AI, driving massive adoption in film/advertising.
Global Expansion as Growth Engine
Chinese vendors capture global markets via cost efficiency and localization: Kling derives >60% revenue overseas; PixaVerse has 16M MAU (90% overseas). Targets expanded from SEA to Japan/Korea/Europe, avoiding domestic traffic saturation.
IV. Future Trends: Breakthroughs & Ecosystem Reshaping
Key 2025-2026 Breakthrough Areas
Extended Length: ByteDance’s CaptainCinema uses keyframe planning + dynamic filling to break 1-minute barrier, unlocking film-grade applications.
Physics Engine Integration: NVIDIA/OpenAI explore injecting fluid dynamics into models for realistic car crashes/water flow.
Real-Time Interactive Gen: Gaming trials for AI-rendered storylines where player choices alter videos—Tencent Hunyuan World is developing this.
Market Sizing & Positioning
Scale: Pro creator market ($3.2B) + Enterprise services ($9.4B) = >$10B. With mass consumer penetration, potential reaches $41.6B.
Ecosystem Strategy: Giants build "model-platform-developer" loops (e.g., Runway for Hollywood); startups specialize in vertical tools (e.g., 3DStyle for fashion AI).
Table: Core Challenges & Solutions in Text-to-Video Industry
| Challenge | Manifestation | Vendor Strategy | Tech Breakthrough Outlook |
|---|
| Compute Limits | Export controls raise training costs | Lightweight models (<10B params) | Quantum computing efficiency |
| Content Homogeneity | Template fatigue | Personalization + style fine-tuning | Brain-computer interface art |
| Copyright/Ethics | Actor protests, ownership ambiguity | Digital watermark + revenue share | Blockchain verification |
| Professional Depth | Falls short for film-grade precision | Integration with tools (e.g., Figma+AI) | Embodied intelligent systems |
V. Critical Challenges: Compute, Ethics & Content Value
Compute & Chip Constraints
U.S. export controls on advanced chips directly impact Chinese model training efficiency. Domestic vendors shift to lightweight models (<10B params) via knowledge distillation, but long-video capabilities still lag.
Ethical & Copyright Dilemmas
Hollywood unions protest AI replacing actors; Runway’s studio partners face backlash. Chinese vendors use digital watermarks for AI content, but training data copyrights remain unresolved. Future requires "revenue sharing" to protect human creators.
Content Value Trap
Templated generation boosts short-video output but causes platform homogenization. User fatigue with "anthropomorphic animal" videos exposes creativity deficits. Solutions must combine human direction—e.g., CaptainCinema lets AI handle keyframe filling while humans control scripts/storyboards.
Conclusion: Democratization & Ecosystem Competition
The text-to-video field will develop a three-tier structure:
Foundation: DiT + multimodal base models (OpenAI, Google)
Middleware: Vertical tools (Runway for film, Kling for short video)
Application: Scenario-specific products (gaming, e-commerce)
In 2 years, 1-minute HD generation and real-time interactive video will mature, expanding the market from billions to tens of billions. Chinese vendors could replicate TikTok’s globalization success via data resources (1.4B user video behaviors) and commercial agility (Kling’s overseas expansion). However, overcoming compute independence and copyright compliance remains essential to balancing "efficiency revolution" with "content value" in defining next-gen visual storytelling. Generative video isn’t just a tech race—it’s a redefinition of human creativity’s boundaries.
