在人工智能技术的推动下，AI视频生成领域正迎来一场前所未有的“权力的游戏”。在这场游戏中，各家AI视频生成神器如同电视剧《权力的游戏》中的各大家族，为了争夺“铁王座”的宝座而展开激烈的竞争。
近日，机器之心对七款被冠以“Sora级”的AI视频生成神器进行了实测，旨在找出能够登上AI视频圈“铁王座”的佼佼者。参与测试的AI视频生成神器包括大洋彼岸的Runway Gen-3、Luma，以及国内的快手可灵、字节即梦、智谱清影、Vidu、PixVerse V2等。
测试内容涵盖文生视频功能，即根据文本描述生成视频的能力。第一项测试要求AI生成意大利布拉诺的五颜六色建筑和一只斑点狗从窗户往外看的场景。结果显示，Runway Gen-3的表现最佳，可灵和即梦也相当出色，画面流畅且精美。
第二项测试则是要求AI生成寄居蟹用灯泡做壳的夜间镜头。在这项测试中，Vidu和Runway Gen-3的视频运动幅度最大，Vidu生成的视频中寄居蟹快速奔跑，而Runway Gen-3则展示了寄居蟹爬动的细节。
第三项测试则是要求AI生成一个机器人在赛博朋克背景下的生活故事。除了Luma未能展示出满意的机器人形象外，其他AI视频生成神器都展现了自己对于未来机器人的想象。
总体来看，Runway Gen-3在运动幅度和逼真程度方面表现优异，但也有小bug存在。各家AI视频生成神器各有千秋，但谁能最终登上“铁王座”，还需进一步观察和测试。这场“权力的游戏”还在继续，而AI视频圈的未来，也将在这些技术的竞争与创新中逐渐揭晓。

Title: “AI Video Generators Clash for the Throne: Who Will Rule the AI Video World?”
Keywords: AI Video, Competition, Effectiveness Evaluation
Content:
Under the impetus of artificial intelligence technology, the AI video generation sector is currently experiencing an unprecedented “Game of Thrones.” In this game, various AI video generators are like the noble families in the “Game of Thrones” series, vying for the throne of the “Iron Throne” in the AI video world.
Recently, Jiemian (Machine Heart) conducted a practical test on seven AI video generators, which were dubbed as “Sora-level,” aiming to find the outstanding winner that could sit on the “Iron Throne” of the AI video circle. The AI video generators tested included Runway Gen-3 and Luma from the other side of the ocean, as well as domestic brands like Kuaishou Ke Ling, Toutiao Jimei, Zhipu Qing Ying, Vidu, and PixVerse V2.
The testing content covered the text-to-video generation capability, meaning the ability to produce videos based on text descriptions. The first test required AI to generate a scene of the colorful buildings of the Burano island in Italy and a spotted dog looking out of a window. The results showed that Runway Gen-3 performed the best, with Ke Ling and Jimei also performing very well, with smooth and beautiful visuals.
The second test was to generate a scene of a hermit crab building a shell with a light bulb at night. In this test, Vidu and Runway Gen-3 exhibited the largest motion, with Vidu’s video showing the hermit crab running quickly, while Runway Gen-3 showcased the details of the hermit crab climbing.
The third test was to generate a story of a robot living in a cyberpunk background. Except for Luma failing to present a satisfactory robot image, other AI video generators showed their imagination of future robots.
Overall, Runway Gen-3 excelled in terms of motion amplitude and realism, but it also had some minor bugs. Each AI video generator has its strengths, but who will ultimately sit on the “Iron Throne” still needs further observation and testing. The “Game of Thrones” is still ongoing, and the future of the AI video world will gradually be revealed through the competition and innovation of these technologies.
