ByteDance's new model sparks stock rally as China's AI video battle escalates

From: SCMP

TikTok parent ByteDance's pre-release of its latest artificial intelligence video model, Seedance 2.0, over the weekend has sent ripples across the tech and video production sectors as competition among Chinese tech titans' AI apps intensifies.

The model – still in beta and available to select users of Jimeng AI, ByteDance's AI video platform – delivered enhanced lifelike video outputs that blurred the boundary between AI content and reality, offered smoother camera movement and improved visual consistency, according to early adopters.

The buzz has sent stock prices rallying across some Chinese media and AI app firms, with analysts hopeful that AI could be further harnessed to benefit traditional filmmaking and content creation. Shares in studio company Huace Media and game developer Perfect World rose around 7 per cent and 10 per cent on Monday, while publishing house COL Group hit its 20 per cent daily price ceiling.

Seedance 2.0 also featured multimodal input, supporting text, image, audio and video-based content generation, making it a handy yet powerful tool for creating video clips that would traditionally have required professional video production and editing skills.

It has drawn widespread attention and early praise, with testers saying they were amazed at its ability to generate lifelike characters as well as provide improved and precise control over editing parts of the video content.

“With its reality enhancements, I feel it's very hard to tell whether a video is generated by AI,” said Wang Lei, a programmer from China's southern Guangdong province.

Wang described using simple text prompts to produce a 10-second clip charting human history from prehistoric times to the modern era, praising the result as “smooth in storytelling with cinematic grandeur”. He credited the vast video data resources available through Douyin – China's largest short-video app and TikTok's Chinese counterpart – with helping ByteDance train the model.

ByteDance's new model sparks stock rally as China's AI video battle escalates

From: SCMP

TikTok parent ByteDance's pre-release of its latest artificial intelligence video model, Seedance 2.0, over the weekend has sent ripples across the tech and video production sectors as competition among Chinese tech titans' AI apps intensifies.

在中国科技巨头的AI应用竞争持续升温之际，TikTok母公司字节跳动于周末抢先发布其最新人工智能视频模型Seedance 2.0，此举迅速在科技界与视频制作行业引发连锁反应。

1）表示“涟漪；微波；细浪”，英文解释为“a small wave on the surface of water”举个🌰：The stone she threw caused ripples to spread across the lake. 她扔了一块石头，湖面泛起阵阵涟漪。

2）表示“（声音的）传播起伏；（感情的）逐渐扩散”，英文解释为“a sound or feeling that spreads through a person or group of people, gradually increasing and then becoming smaller”如：A ripple of laughter/applause 一阵阵笑声/掌声。

补充：

📍ripple effect表示“连锁反应”，英文解释为“a situation in which one event produces effects which spread and produce further effects”举个🌰：The bank crash has had a ripple effect on the whole community. 银行的破产在整个社区引起了连锁反应。

titan /ˈtaɪ.tən/表示“巨人；巨头；泰斗”，英文解释为“If you describe someone as a titan of a particular field, you mean that they are very important and powerful or successful in that field.”如：an intellectual titan 学界泰斗。

The model – still in beta and available to select users of Jimeng AI, ByteDance's AI video platform – delivered enhanced lifelike video outputs that blurred the boundary between AI content and reality, offered smoother camera movement and improved visual consistency, according to early adopters.

据首批体验者反馈，该模型目前仍处于测试阶段，仅向字节跳动旗下AI视频平台即梦AI的部分用户开放；其生成效果更加逼真，进一步模糊了AI内容与现实影像的界限，同时在镜头运动流畅度与画面一致性方面也有明显提升。

beta，希腊字母表的第2个字母β，表示“（软件程序）尚未投放市场，处于第二个开发阶段的”，英文解释为“Beta software is at the second stage of development.”

blur /blɜːr/ 作动词，表示“（使）变模糊”，英文解释为“to (make something or someone) become difficult to see clearly”或者表示“使…的区别不明显；使难以了解…的真相”，英文解释为“to make the difference between two things less clear, or to make it difficult to see the exact truth about something”举个🌰：This film blurs the line/distinction/boundary between reality and fantasy. 这部电影模糊了现实与幻想的界限。

作名词，表示“模糊形状；模糊的东西”，英文解释为“a shape that you cannot see clearly, often because it is moving too fast”举个🌰：If I don't wear my glasses, everything is just a blur. 如果不戴眼镜，我看任何东西都是模糊的。

The buzz has sent stock prices rallying across some Chinese media and AI app firms, with analysts hopeful that AI could be further harnessed to benefit traditional filmmaking and content creation. Shares in studio company Huace Media and game developer Perfect World rose around 7 per cent and 10 per cent on Monday, while publishing house COL Group hit its 20 per cent daily price ceiling.

这一热潮也迅速传导至资本市场，多家中国传媒及AI应用相关公司股价走高。分析人士普遍看好I技术进一步赋能传统影视制作与内容创作。周一，华策影视与完美世界股价分别上涨约7%和10%，出版公司中文在线则触及20%的日涨停板。

buzz /bʌz/ 的本义是指“嗡嗡声，蜂鸣声”（a continuous noise like the sound of a bee），还有“闹哄哄；喧闹”（a lot of activity, noise, and excitement）、“兴奋之感，喜悦心情”（a strong feeling of excitement, pleasure, or success, or a similar feeling from drinking alcohol or taking drugs）的含义。

此处buzz，韦氏词典（Merriam-Webster）给出的英文解释为：“speculative or excited talk or attention relating especially to a new or forthcoming product or event”或者是“an instance of such talk or attention”，（引起）关注/热议等，如：their first song created a huge buzz 他们的第一首引起热烈反响，create a buzz 制造话题，造势，炒作，制造噱头。

📍此外，比较常见的一个词buzzword，表示“流行语，热词，时髦用语，流行术语”（a word or phrase from one special area of knowledge that people suddenly think is very important）

harness /ˈhɑː.nəs/ 表示“挽具；系带”，英文解释为“a piece of equipment with straps and belts, used to control or hold in place a person, animal, or object”如：a safety harness 安全带。

🎬《复仇者联盟2：奥创纪元》（Avengers: Age of Ultron）中提到的：If we can harness this power, ...如果我们能够驾驭这种能量，

🎬《奇异博士》（Doctor Strange）中提到的：We harness energy...我们收集/汲取能量，

ceiling /ˈsiː.lɪŋ/ 表示“天花板，顶棚”，英文解释为“the inside surface of a room that you can see when you look above you”，也可以表示“（通常指钱款的）上限”，英文解释为“an upper limit, usually relating to money”举个🌰：They have imposed/set a ceiling on pay rises. 他们给工资的增加额度规定了上限。

Seedance 2.0 also featured multimodal input, supporting text, image, audio and video-based content generation, making it a handy yet powerful tool for creating video clips that would traditionally have required professional video production and editing skills.

Seedance 2.0同时具备多模态输入能力，支持基于文本、图像、音频及视频的内容生成，使其成为一款兼具便捷性与功能性的工具，可完成以往往往需要专业视频制作与剪辑技能的创作任务。

It has drawn widespread attention and early praise, with testers saying they were amazed at its ability to generate lifelike characters as well as provide improved and precise control over editing parts of the video content.

该模型已引发广泛关注并收获初步好评。测试者表示，其在生成高度拟真的人物形象方面表现出色，同时在视频局部编辑的精度与可控性上也展现出显著优势。

“With its reality enhancements, I feel it's very hard to tell whether a video is generated by AI,” said Wang Lei, a programmer from China's southern Guangdong province.

“在真实感增强方面，我觉得已经很难分辨一段视频是否由AI生成，”来自中国南方广东省的程序员王磊表示。

Wang described using simple text prompts to produce a 10-second clip charting human history from prehistoric times to the modern era, praising the result as “smooth in storytelling with cinematic grandeur”. He credited the vast video data resources available through Douyin – China's largest short-video app and TikTok's Chinese counterpart – with helping ByteDance train the model.

王磊介绍说，他仅通过简单的文本提示词便生成了一段10秒视频，展现从史前时代到现代社会的人类历史，并称赞成片“叙事流畅且富有电影般的宏大感”。他认为，字节跳动能够训练出这一模型，离不开抖音这一中国最大短视频平台所积累的海量视频数据资源。

prompt /prɒmpt/ 作名词，1）表示“（计算机屏幕上的）提示符（显示计算机已经准备好接受指令）”，英文解释为“a sign on a computer screen that shows that the computer is ready to receive your instructions”

📍在ChatGPT火热的今天，prompt通常指的是给模型的输入，用来激发或引导模型生成特定的输出或回答。简而言之，prompt是指用户提供给语言模型的一段文字或命令，以便模型据此理解用户的需求并给出相应的响应或信息。例如，在与像ChatGPT这样的大语言模型交互时，用户提出的问题或指令就是一个“prompt”。模型会根据这个prompt的内容分析、处理并生成回答或执行相关的任务。Prompt对于大语言模型来说是非常关键的，因为它直接决定了模型如何理解和回应用户的需求。

📍prompt中文里有译为“提示词”，prompt engineering 就是“提示工程/提示词工程”

2）表示“（给演员的）提词，提白”，英文解释为“words that are spoken to an actor who has forgotten what he or she is going to say during the performance of a play”

3）作动词，表示“促使；导致；激起”，英文解释为“to make sb decide to do sth; to cause sth to happen”举个🌰：His speech prompted an angry outburst from a man in the crowd. 他的讲话激起了人群中一男子的愤怒。

📺美剧《斯巴达克斯：血与沙》（Spartacus: Blood and Sand）中的台词提到：One cannot but wonder what would prompt such an act 不知他们为何遭此不幸。

4）作动词，表示“（尤指）给（演员）提词”，英文解释为“to help someone, especially an actor, to remember what they were going to say or do”举个🌰：I forgot my line and had to be prompted. 我忘词了，只好让人提词。

prehistoric /ˌpriː.hɪˈstɒr.ɪk/ 表示“史前的，有文字记载的历史以前的”，英文解释为“describing the period before there were written records”如：prehistoric man/humans/animals 史前人类/动物。

grandeur /ˈɡræn.dʒər/ 表示“宏伟，壮丽，堂皇”，英文解释为“the quality of being very large and special or beautiful”如：the silent grandeur of the desert 沉寂而壮丽的沙漠。
