A heartwarming one-and-a-half-minute animated short, featuring a lovable polar bear embarking on a journey across mountains and seas to meet penguins in Antarctica, was completed by AI in just one week—four times faster than traditional methods.

“I handle the imagination and experimentation; AI handles the adjustments and rendering.” This is how a former tech professional turned freelance AI director describes his new workflow. With the emergence of AI video generation models like Sora, Veo 3, and Kling, the once-complex process of video production is being dramatically simplified. From a simple text prompt to a dynamic video, the barriers to creation have never been lower.

01 Redefining Creative Boundaries

Imagine typing a sentence and watching AI generate a crisp, one-minute高清 video. This is no longer science fiction.

When OpenAI unveiled its text-to-video model Sora in early 2024, the industry gasped. Many declared that the “GPT moment” for AI video had arrived.

The journey here spanned nearly three years of iterative exploration. Early AI videos resembled silent films, requiring separate audio dubbing and specialized tools to lip-sync characters convincingly.

Sora marked a pivotal breakthrough in February 2024. Its core innovation lies in replacing the traditional convolutional U-Net in diffusion models with a Transformer-based neural network architecture, pioneering a new path known as Diffusion Transformers (DiT).

Sora can accurately follow text instructions to generate videos up to 60 seconds long, with impressive realism and coherence. The process mirrors how a sculptor reveals a statue from stone, as AI progressively removes “noise” from an initial random state to unveil a clear,连贯 narrative.

02 The Toolkit for a New Generation of Creators

Let’s explore the leading tools reshaping the creative landscape.

• OpenAI’s Sora: Remains an industry benchmark. This revolutionary model generates high-quality videos from text prompts, mastering complex scene还原, multi-angle shots, and plausible physics simulation. Experts note its DiT path effectively leverages “world knowledge” learned from large language models to aid visual world generation.
• Google’s Veo 3: Pushing boundaries further by integrating audio from the start. It generates talking subjects with fluent speech, natural lip-syncing, and fitting environmental sound effects—all同步 with the visual scene.
• Kling AI: Made waves by launching its Kling 2.0 model internationally in April 2025, followed by the enhanced 2.1 series in May. The 2.1 series offers standard (720p) and high-quality (1080p) modes, boasting leading efficiency—generating a 5-second HD video in under a minute.
• ByteDance’s Doubao Seedance: Topped international benchmarks for both text-to-video and image-to-video tasks. Its user-friendly interface lets creators upload an image or enter a text prompt to bring their ideas to life.

03 Current Challenges and Limitations

Despite rapid progress, the technology faces significant hurdles.

First, the computational cost is immense. Running models with tens of billions of parameters requires cutting-edge GPUs to process for dozens of seconds or minutes per minute of 1080p video.

Second, the problem of “AI hallucinations” persists. Models may generate physically implausible content. As Professor Hu Yong from Peking University notes, “Hallucinations may decrease with technological iteration but can never be完全 eliminated. The risk of failure always exists.”

The technical difficulty is staggering. As Associate Professor Shen Huaqing from Zhejiang University explains, “A mere 5-second video at 24 fps requires 120连贯 images. Ensuring consistency across all frames is like coordinating 120 painters on a single canvas—every stroke must align perfectly.”

04 Empowering Industries and Streamlining Production

AI video generation is transforming content creation across sectors.

Director Luo Chong shares his workflow: “Leveraging multiple tools is essential.” He combines models for their strengths. “I imagine and experiment; AI adjusts and renders. This massively boosts creativity while cutting costs.”

In professional filmmaking, the impact is profound. Zhejiang BOCAI Media’s approach, termed “virtual production,” blends AI with traditional techniques. They developed proprietary software to integrate various AI tools, tripling efficiency and slashing costs by at least one-third.

Niu Cong from BOCAI adds that in filmmaking, AI acts as a powerful assistant to directors and producers, enabling real-time pre-visualization so “the quality of an idea is immediately visible.”

Beyond entertainment, this technology enhances education through dynamic 3D simulations and revolutionizes advertising.

05 Towards a “World Simulator”

The ultimate vision, as framed by OpenAI, is to develop AI video as a “world simulator”— a form of artificial general intelligence that comprehends and interacts with reality.

Critics like Professor Zhu Songchun question whether sheer scale alone can achieve true intelligence. Yet, progress continues. Platforms like Alibaba’s “Zaodian” can now auto-generate coherent narratives with voice-overs, sound effects, and sophisticated cinematography in a single generation.

The technology is rapidly advancing toward longer durations, higher resolutions, and finer-grained control.

The award-winning AI-assisted animation All the Way South, featured at the Beijing International Film Festival, symbolizes this shift. Completing in one week what traditionally took a month, it showcases the tangible power of today’s AI tools.

As one industry insider predicts, “An era where everyone can be a designer and a director is coming,” much like when social media gave everyone a voice. The tools are here, turning imagination directly into screen reality.
