How to Prompt Grok Imagine Video 1.5

xAI has newly released Grok Imagine Video 1.5. The core purpose of this model is to convert a single static image into a short video, and within the same generation flow to add audio that is synchronized with the visuals. In other words, after the user provides static material, the model completes both animation and sound generation in one pass, rather than requiring the user to first create the video and then separately find sound effects, background music, or perform post-production synchronization. This Replicate Blog article is positioned as a prompt tutorial, with the focus on explaining how to write prompts in order to more fully leverage the capabilities of Grok Imagine Video 1.5. The information that can be confirmed from the provided original summary includes: the model is released by xAI, the input is a static image, the output is a short video, and the generated result includes synchronized audio. This capability has direct reference value for creators and designers who need to quickly extend an image into audiovisual content, and it is also worth watching whether generative video tools are gradually integrating what were originally separate tasks—visual animation, sound production, and synchronization—into a single flow. However, the provided original excerpt does not explain the video length, resolution, controllable camera parameters, supported formats, pricing, or generation speed, nor does it list specific prompt examples or limitations. Therefore, this article can only be regarded as an introduction to a prompt usage guide for Grok Imagine Video 1.5, and cannot be used to infer the model's performance in terms of image quality, stability, or in comparison with other video models.
