Adobe 展示即将推出的生成式 AI 视频工具,包括从图像生成视频片段等功能,其新视频模型将用于多种应用的 AI 视频和音频编辑,部分功能今年晚些时候以测试版推出。

🎬 Adobe 即将推出的生成式 AI 视频工具中,新功能可从静态图像制作视频片段,基于 Firefly 视频模型,用户可用文字描述生成视频并通过多种‘相机控制’调整结果。

🎥 Adobe 的新 AI 视频工具允许用户选择预设拍摄风格,其生成的视频质量与 OpenAI 的 Sora 模型相当,但视频时长有限,最长为 5 秒。

💪 Adobe 模型的优势之一是 Firefly 基于公开许可、公共领域和 Adobe Stock 内容训练,具有‘商业安全性’,可减少版权侵权担忧。

Adobe has teased some of its upcoming generative AI video tools, including a new feature that can produce video clips from still images. This latest preview builds on the in-development Firefly video model that the software giant demonstrated in April, which is set to power AI video and audio editing features across Adobe’s Creative Cloud applications.

The new promotional teaser shows footage produced by Firefly’s text-to-video capabilities that Adobe announced (but didn’t demonstrate) earlier this year. The tool allows users to generate video clips using text descriptions and adjust the results using a variety of “camera controls” that simulate camera angles, motion, and shooting distance. An image-to-video feature was also demonstrated for the Firefly video model that can generate clips using specific reference images. Adobe suggests this could be useful for making additional B-roll footage or to patch gaps in production timelines.

Adobe’s new AI video tool will allow users to choose preset filming styles to emulate, alongside describing their desired footage.

If the example footage is any indication of the final release, the generated video quality looks on par with what we’ve seen from OpenAI’s Sora model so far, which Adobe is also “exploring” as a third-party integration for its Premiere Pro video software. Duration is limited, though, with Adobe’s VP of generative AI, Alexandru Costin, telling The Verge that videos produced by the text-to-video and image-to-video features have a maximum length of five seconds.

One advantage Adobe’s own model may have against Sora is its promise that Firefly is “commercially safe” due to being trained on openly licensed, public domain, and Adobe Stock content, which could reduce some concerns about copyright infringement.

The text-to-video and image-to-video features will both initially be available in beta as a standalone Firefly application sometime later this year. Adobe says the new Firefly video model will eventually be integrated into its Creative Cloud, Experience Cloud, and Adobe Express applications.

The company also showed off some additional clips of the upcoming “Generative Extend” feature for Premiere Pro that can extend the length of existing video footage, similar to Photoshop’s Generative Expand tool for image backgrounds. Adobe says this will also be arriving on an unspecified date “later this year.”
