Adobe正式发布了其文本和图像转视频的AI生成器Generate Video的公开测试版。该工具基于Firefly视频模型,用户可以通过重新设计的Firefly网页应用程序访问,并集成了新的图像生成和翻译功能。Generate Video包含文本转视频和图像转视频两个功能,最高输出1080p分辨率的视频,但最长只有5秒。Adobe还更新了Firefly网页应用程序,与Creative Cloud应用程序集成,方便用户移动和编辑AI生成的资产。此外,Adobe还推出了新的Firefly订阅计划,提供用于使用Firefly模型的积分。

✨Adobe发布Generate Video公开测试版,该工具基于Firefly视频模型,包含文本转视频和图像转视频两个功能,允许用户通过文本描述或参考图像生成短视频片段。

📹Generate Video输出视频最高可达1080p分辨率,帧率为24fps,但目前生成的视频最长只有5秒,生成一个片段需要90秒甚至更长时间。Adobe正在开发速度更快、分辨率更低的“构思模型”以及4K模型。

🎨Firefly网页应用程序迎来更新,拥有全新的用户界面,并与Photoshop、Premiere Pro和Express等Creative Cloud应用程序集成,方便用户移动和编辑AI生成的素材。由于Firefly使用公共领域和授权内容进行训练,因此可以安全地用于商业用途。

💰Adobe推出两种新的Firefly订阅计划,分别是Firefly Standard和Firefly Pro,价格分别为每月9.99美元和29.99美元,分别提供2000和7000视频/音频积分,可用于生成5秒的1080p视频,并且都包含无限制访问Firefly图像和矢量功能。

Adobe’s text- and image-to-video AI generator has been released for anyone to try online. Generate Video is available starting today in public beta following a limited early access testing period last year. The beta tool can be accessed via the re-designed Firefly web app, alongside new image generation and translation capabilities, and AI credit subscription tiers for creators.

Adobe started launching tools powered by its generative AI Firefly Video Model in October, starting with the Generative Extend tool in beta for Premiere Pro that can be used to extend the end or beginning of footage. The Generate Video tool rolling out today — over two months after OpenAI launched its own text-to-video generator, Sora — adds some minor improvements since it was first teased in September.

Generate Video consists of two features: Text-to-Video and Image-to-Video. As those names imply, Text-to-Video allows users to generate footage using text description, while Image-to-Video lets you add a reference image alongside the prompt to provide a starting point for the video. Generate Video includes various options that refine or guide the results, such as simulating styles, camera angles, motion, and shooting distances.

Video is now output in 1080p at 24 frames per second, up from the original 720p quality. Both Text-to-Video and Image-to-Video take 90 seconds or longer to generate clips at a maximum length of five seconds — shorter than the 20-second duration available to Sora users. Adobe says it’s also working on both a faster, lower-resolution “ideation model” and a 4K model, which are “coming soon.”

Adobe has also updated the Firefly web app that hosts many of its generative AI tools. Alongside sporting a new UI, it now integrates with Creative Cloud apps including Photoshop, Premiere Pro, and  Express, making it easier to move and edit AI-generated assets. And because Firefly is trained on public domain and licensed content, it’s safe for commercial use. Adobe even describes its Generate Video tool as “production-ready” to entice users who want to use AI-generated videos in films without the risk of violating copyright protections.

Adobe faces growing competition in the AI video market. In addition to Sora, Google is testing the second generation of its Veo AI video model, which looks more impressive than OpenAI’s model judging by early demo examples. ByteDance and Pika Labs have also recently announced new video-focused generative AI tools. Adobe’s main advantage is Firefly’s commercial viability, but it will still need to keep up with the quality and features its competitors are offering.

Two additional tools will also be available in public beta on the Firefly web app starting today — but these aren’t free to use. Scene to Image lets users create their own references for AI-generated images using built-in 3D and sketching features — seemingly built on the “Project Scenic” experiment that Adobe announced in October. The Translate Audio and Video tool is pretty self-explanatory, allowing users to translate and dub audio into over 20 languages while preserving the original speaker’s voice.

Adobe is launching two new Firefly subscription plans which provide credits that can be spent to use Adobe’s Firefly models. Firefly Standard starts at $9.99 per month for 2,000 video/audio credits and provides up to 20 five-second 1080p video generations. The pricier Firefly Pro plan starts at $29.99 for 7,000 credits and up to 70 five-second 1080p video generations. A notable perk is that both plans include unlimited access to Firefly imaging and vector features.
