[Strengths] It excels at restyling and modifying an existing video while keeping its original duration and aspect ratio. [Best For] Highly recommended for: restyling clips, applying visual effects, and prompt-driven video edits. [Limitations] Do NOT use this model to change the duration, aspect ratio, or resolution; the output preserves the input video's duration and aspect ratio, and those parameters are not configurable. Input video constraints (e.g. format/length) are enforced by the upstream provider. [Routing] Use this model when the user provides a video and wants it edited/restyled. To make a video longer, use Video Extend. ## OpenAPI ````yaml /model-api/xai/xai-v2v.json post /xai/grok-imagine-video-edit openapi: 3.1.0 info: description: >- The video-to-video models API from xAI Grok Imagine.
