随着人工智能技术的飞速发展，2023年被誉为AI视频元年。在这一年中，AI视频领域取得了显著的进展，从年初的文本转视频模型的空白，到年末数十种视频生成产品的问世，这一转变不仅令人瞩目，也极大地推动了视频内容的创作与分享。
A16Z合伙人Justine Moore在2024年的AI视频展望中指出，尽管2023年对于AI视频领域来说是突破性的一年，但该领域仍面临着不少挑战。目前，大多数AI生成的视频时长在3～4秒之间，且视频质量参差不齐。此外，像角色一致性这样的问题还未得到有效解决，这意味着我们距离用单一文本提示（或甚至多个提示）创造出皮克斯级别的短片还有很长的路要走。
Justine Moore强调，尽管存在这些局限性，AI视频技术的发展仍然值得期待。随着技术的不断进步，未来我们有望看到更加流畅、高质量的视频内容，以及更加智能的视频生成工具。这些工具不仅能够帮助用户快速创建视频，还能够提供更加丰富的创作选项和个性化体验。
总的来说，2023年的AI视频技术已经取得了令人瞩目的成就，但仍需解决诸多技术难题。2024年，随着技术的进一步发展，我们有理由相信，AI视频领域将迎来更加广阔的发展空间，为用户带来更加丰富和优质的视频体验。

The year 2023 has been hailed as the AI Video Year, marking a significant leap in the field of artificial intelligence. From the beginning of the year, where there was a void in text-to-video models, to the end of the year, where dozens of video generation products have emerged, this transformation has not only been remarkable but has also greatly propelled the creation and sharing of video content.
Justine Moore, a partner at A16Z, highlighted in her 2024 AI Video Outlook that although 2023 was a breakthrough year for AI video, the field still faces numerous challenges. Most AI-generated videos are currently between 3 to 4 seconds long, and the quality varies greatly. Moreover, issues like character consistency have yet to be effectively addressed, indicating that we are still far from creating Pixar-level short films with a single text prompt (or even multiple prompts).
Justine Moore emphasized that despite these limitations, the development of AI video technology is still worth looking forward to. With the continuous progress of technology, we can expect to see more seamless and high-quality video content, as well as more intelligent video generation tools in the future. These tools will not only help users create videos quickly but also provide richer creative options and personalized experiences.
In summary, the AI video technology of 2023 has achieved remarkable achievements, but many technical problems still need to be solved. In 2024, with the further development of technology, we have reason to believe that the AI video field will embrace a broader development space, bringing users a richer and higher-quality video experience.
