## Overview Grok Imagine Video 1.5 by xAI animates a single still image into a short video clip. You provide a first frame and a text prompt that describes motion, camera moves, and mood. The model generates an MP4 video and may include a synchronized audio track, so you can share a complete clip without separate sound design. ## What you can build - Product spins and hero shots from a single product photo - Portrait animations with subtle head turns, hair movement, and camera push-ins - Concept art previews that add motion, atmosphere, and cinematic framing - Social ad variants in common aspect ratios (landscape, portrait, square) - Meme and poster animations for short-form platforms ## Inputs - One first-frame image file in JPG, JPEG, or PNG format. The file must be 20 MiB or smaller. Only 1 image is allowed. - A required text prompt that describes the motion you want to see. Focus on actions, camera movement, and timing. Keep the prompt under 4,096 characters. - A clip duration selection in seconds. Choose 5, 10, or 15 seconds. - An aspect ratio setting. Use Auto to match the source image, or override it with ratios like 16:9, 9:16, 1:1, 4:3, 3:4, 3:2, or 2:3. - An output resolution selection: 480p or 720p. ## Outputs - A generated MP4 video file. - A structured result that includes the downloadable video location plus useful metadata. Metadata typically includes the file type, file size, pixel width and height, frame rate, clip duration, and total frame count. ## Recommended settings - Start with 5 seconds for the most stable motion and fewer artifacts. - Use 720p when you need clearer faces and product details. - Use 480p for quick iterations and draft passes. - Write prompts like a shot list. Describe camera moves (pan, tilt, dolly, orbit) and the main action. ## Limitations - This listing is image-to-video. It needs a starting image and does not support text-only video generation. - Clips top out at 15 seconds per generation. - Output resolution is limited to 480p or 720p. - Negative prompts may be ignored. Say what you want to see instead. - Low-quality inputs can degrade results. Heavily compressed images, screenshots with artifacts, motion-blurred photos, or scanned images can cause flicker, warping, or texture crawl. - Download links for generated files can be temporary. Save the result if you need long-term access. ## Safety & compliance - Outputs may be filtered or blocked by content moderation. - Don’t use it to create sexual content involving minors, non-consensual intimate imagery, or realistic impersonation meant to deceive. - Get consent before generating videos of real people for sensitive or commercial use.
