YouTube在其Made on YouTube活动中宣布了一系列专为Shorts创作者设计的新型生成式AI工具。其中包括Google的文本到视频模型Veo 3的定制版本Veo 3 Fast,该版本能以较低延迟生成480p视频,并首次支持音频生成。此外,还引入了新的混音工具,允许创作者将现有视频的对话转化为Shorts的配乐,利用Google的Lyria 2音乐AI模型,并可自定义歌曲风格。一项名为“Edit with AI”的功能则能将原始素材自动剪辑成初稿,添加音乐、转场甚至画外音。这些新功能将逐步在美国及其他地区推出,旨在简化内容创作流程,激发创作者的灵感。

🎬 **AI驱动的视频生成与增强**:YouTube为Shorts引入了Veo 3 Fast,这是Google文本到视频生成式AI模型的定制版本,能以更快的速度生成480p的视频片段,并首次支持音频输出,极大地提升了视频创作的效率和表现力。

🎶 **创新的音频混音功能**:新的混音工具允许创作者将现有视频中的精彩对话转化为引人入胜的Shorts配乐。借助Google的Lyria 2 AI音乐模型,用户可以将这些提取的音频片段转化为歌曲,并能根据“Chill”、“Danceable”或“Fun”等风格进行个性化调整,为内容增添独特的声音魅力。

✍️ **“Edit with AI”简化创作流程**:这项名为“Edit with AI”的新功能旨在为创作者提供一个便捷的起点。它能够智能地分析原始拍摄的素材,自动筛选并排列出最佳的片段,同时添加合适的音乐和转场效果。该功能甚至支持生成画外音,能够根据视频内容做出反应,进一步简化了Shorts的后期制作过程。

🌍 **逐步推广与全球化**:这些新的人工智能工具的推出并非一蹴而就。Veo 3 Fast和一些核心的AI视频编辑功能已在美国、英国、加拿大、澳大利亚和新西兰等地区开始推送,而其他功能如“Speech to Song”混音工具的测试和推广也将逐步展开,预示着YouTube将持续在全球范围内扩展其AI创作能力。

At its Made on YouTube live event on Tuesday, the company unveiled new generative AI tools for Shorts creators. YouTube is bringing a custom version of Google’s text-to-video generative AI model, Veo 3, to Shorts, along with a new remixing tool, an “Edit with AI” feature, and more.

The custom version of Veo 3, called Veo 3 Fast, generates outputs with lower latency at 480p, making it easy to create video clips, YouTube says. And now, users can do so with sound for the first time.

This update is rolling out in the United States, the United Kingdom, Canada, Australia, and New Zealand. YouTube plans to expand its functionality to more regions in the future.

YouTube is also bringing new Veo capabilities to Shorts, including the ability to apply motion from a video to an image. For example, you could animate a still image by making the person in it do a dance from a video. The company says this is possible through technology that captures and transfers movement from one subject to another.

Creators can now also use Veo to apply different styles to their videos, such as pop art or origami. Plus, creators now have the ability to add objects like characters or props with text descriptions.

These new capabilities will roll out in the coming months.

As for the new remixing tool, creators can turn the dialogue from eligible videos into catchy soundtracks for other Shorts.

“As the world’s largest creative playground, YouTube is where trends are born and where you can draw inspiration from. Imagine hearing a line of dialogue that sparks an idea—a funny phrase, a memorable quote, or a one-of-a-kind sound—and you want to remix it into a new sound,” YouTube’s Director of Product, Shorts and Generative AI Creation, Dina Berrada wrote in a blog post. “With our new Speech to Song remixing tool, you’ll be able to do just that.”

YouTube notes that the feature uses Google’s AI music model Lyria 2 to create the soundtrack. Creators will be able to add their own vibe to the song, like “chill,” “danceable,” or “fun.”

The company plans to test this feature soon, it says, and will roll it out to more creators in the United States in the coming weeks.

With the new Edit with AI feature, creators can turn their raw footage into first drafts. It transforms raw camera roll footage into a first draft by finding and arranging the best moments, adding music, and transitions. It can even add a voiceover that can react to what’s happening in the video, in either English or Hindi. The idea behind the feature is to give creators a starting point for their Shorts, YouTube says.

YouTube is experimenting with Edit with AI on Shorts and in the YouTube Create app, and will expand the feature in the coming weeks in select markets.
