xAI 发布 Grok Imagine 1.5 预览版（图像转视频模型）
阅读原文· x.aixAI的新视频模型从单张图像生成电影级短片，支持自然语言控制运镜和氛围，对视频创作者和开发者是个值得一试的工具。
xAI 通过 API 发布了图像转视频模型 grok-imagine-video-1.5-preview（Grok Imagine 1.5 预览版）。该模型能将单张静态图片转为流畅的电影感视频，用户提供起始帧和描述运动的提示词后，模型可生成包含相机移动、氛围和物理效果的动画，并保持对源图像的忠实。支持生成 720p 片段，可使用自然语言指令控制镜头、节奏和音效，并支持逐帧拼接成长场景。模型目前通过 xAI API 提供预览使用。

Our latest image-to-video model, grok-imagine-video-1.5-preview, is now available via the xAI API in preview.
grok-imagine-video-1.5-preview turns a single still image into fluid, cinematic video. Give it a starting frame and a prompt describing the motion, and it animates the scene, including camera moves, atmosphere, and physics, while staying faithful to your source image. You can generate clips at up to 720p.
Direct the shot with natural-language prompts. Describe the camera move, the pacing, and the sound design, then set your resolution and clip length. The model holds detail and lighting from the input frame, so the result continues the original image rather than reinterpreting it.
The model also works well for sequences. Stage each frame, animate it, and chain the shots together into longer scenes that keep a consistent look across an entire project.
Animate an image in a few lines of code.
