外媒实测 Sora 生成视频：仍存缺陷，颠覆影视业尚远
据外媒 Bloomberg 报道，近日其记者亲身体验了人工智能视频生成工具 Sora，发现其生成的视频存在翻车现象，并且生成速度极慢。
Sora 是由人工智能公司 RunwayML 开发的一款视频生成工具，号称可以根据文本描述生成逼真的视频。Bloomberg 记者测试发现，Sora 生成的视频在处理身体部位和物理学原理时存在缺陷。例如，它生成的动物变形视频中，动物的肢体扭曲变形，动作不自然；在速度测试中，Sora 生成的视频速度缓慢，与实际情况相差甚远。
此外，Sora 的生成速度也是一个大问题。Bloomberg 记者表示，Sora 处理一个简单的请求需要数小时，这使得它在实际应用中非常不切实际。
Bloomberg 认为，尽管 Sora 在生成视频方面令人印象深刻，但它尚未准备好颠覆影视业。原因就在于，Sora 对于身体部位的理解和物理学的复杂原理还无法完全掌握，并且，它处理请求的时间实在是太长了。
业内人士指出，Sora 目前的缺陷是人工智能视频生成技术普遍存在的问题。人工智能模型需要大量的训练数据和复杂的算法才能生成逼真的视频，而这需要大量的计算资源和时间。
因此，人工智能视频生成技术要想真正颠覆影视业，还需要进一步的发展和完善。

According to a hands-on test by Bloomberg, the AI video generationtool Sora still has flaws and is far from revolutionizing the film industry.
Sora, developed by AI company RunwayML, claims to generate realistic videos from text descriptions. However, Bloomberg’s test revealed that Sora’s videos suffer from imperfections in handling body parts and physics. For instance, in a video of ananimal morphing, the animal’s limbs twisted unnaturally, and in a speed test, Sora’s video was significantly slower than real-world footage.
Sora’s generation speed is also a major issue. Bloomberg’s tester reported that Sora took hours to process a simple request, making it impractical for real-world applications.
Bloomberg concluded that while Sora is impressive in its ability to generate videos, it is not yet ready to disrupt the film industry. This is because Sora’s understanding of body parts and complex physics is still lacking, and its processing times are simply too long.
Industry experts note that Sora’scurrent shortcomings are common to AI video generation technology. AI models require vast amounts of training data and sophisticated algorithms to generate realistic videos, which in turn require significant computational resources and time.
Therefore, AI video generation technology still needs further development and refinement before it can truly revolutionize the film industry.
