China’s Tech Giants Ramp Up Efforts in Video Generation: A Closer Look at Tencent’s DynamiCrafter
Tencent Releases New Version of Open Source Video on Monday, Showcasing its Dominance in the Chinese Internet with Gaming Empire and WeChat Chat App
China’s race to create generative videos is getting hotter with ENBLE.
On Monday, Tencent, the Chinese internet giant, made a splash in the tech world by unveiling the latest version of its open source video generation model, DynamiCrafter, on GitHub. This announcement serves as a reminder that some of China’s biggest tech firms are quietly making strides in the text- and image-to-video space. But what exactly is DynamiCrafter and what sets it apart from its competitors?
The Power of Diffusion: Turning Captions and Images into Lively Videos
DynamiCrafter, like other generative video tools on the market, utilizes the diffusion method to transform captions and still images into captivating videos. Inspired by the phenomenon of diffusion in physics, the diffusion technique in machine learning allows simple data to be converted into more complex and realistic data. It’s similar to how particles move from areas of high concentration to areas of low concentration.
In the case of DynamiCrafter, the second generation of this tool is capable of producing videos at a pixel resolution of 640×1024, a significant upgrade from its initial release in October, which only supported 320×512 videos. The team behind DynamiCrafter explains in an academic paper that their technology sets itself apart from competitors by broadening the applicability of image animation techniques to “more general visual content.” While traditional techniques focus on animating natural scenes or domain-specific motions, DynamiCrafter incorporates the image into the generative process, utilizing motion prior of text-to-video diffusion models.
DynamiCrafter in Action: A Glimpse into the Animated World
To get a sense of how DynamiCrafter compares to other video diffusion models, a demo was conducted, pitting DynamiCrafter against Stable Video Diffusion (launched in November) and the recently hyped-up Pika Labs. While it’s important to note that the chosen samples in the demo may favor DynamiCrafter, the Tencent model appears to produce slightly more animated results compared to its counterparts. However, even after a few tries, none of the models give the impression that AI will soon be able to produce full-fledged movies.
The Rise of Generative Videos in the AI Race
Generative videos have garnered significant attention as the next frontier in the AI race, following the success of generative text and images. Startups and tech giants alike are investing substantial resources in this field, and China is no exception. Alongside Tencent, other major players such as ByteDance (the parent company of TikTok), Baidu, and Alibaba have also released their own video diffusion models.

Both ByteDance’s MagicVideo and Baidu’s UniVG have posted demos on GitHub, though they are not yet available to the public. Like Tencent, Alibaba has taken the open source route by making its video generation model, VGen, accessible to the global developer community. It’s clear that these efforts reflect the growing interest and potential of generative videos.
Q&A: Addressing Further Questions and Concerns
Q: Can DynamiCrafter be used for professional video production?
A: While DynamiCrafter shows promise in creating animated videos from text and images, it currently falls short of producing content suitable for full-fledged professional video production. However, as AI technology continues to evolve, we can anticipate significant advancements in the field.
Q: Are there any ethical concerns surrounding generative video technology?
A: Generative video technology raises ethical questions regarding the potential misuse of AI-generated content. As these tools become more sophisticated, precautions must be taken to ensure authenticity and prevent the spread of misleading or fabricated information.
Q: How will generative videos impact the entertainment industry?
A: While generative videos have the potential to enhance creativity and streamline the video production process, they are unlikely to replace the need for human creativity and expertise in the entertainment industry. Rather, these tools can serve as powerful aids for content creators, enabling them to bring their ideas to life more efficiently.
The Future of Video Generation and AI
The release of DynamiCrafter and other video diffusion models by major Chinese tech firms highlights the growing significance of generative videos in the AI landscape. As research and development in this field continue, we can expect further advancements in the technology, pushing the boundaries of what AI can achieve in creative content generation.
