The #1 Image-to-Video Model by xAI
Grok Imagine Video 1.5 is xAI's latest image-to-video generation model, officially released on May 31, 2026. It secures the #1 position on the Arena.ai Image-to-Video leaderboard with a massive +52 Elo point improvement over the previous version, outperforming Seedance 2.0, HappyHorse 1.0, and Google Veo. Built on the Aurora engine, it animates still images into short videos with synchronized audio — handling visual generation and audio synthesis in one seamless pass.
#1 on Image-to-Video Leaderboard
Grok Imagine Video 1.5 Preview (720p) officially ranks #1 on the Arena.ai Image-to-Video leaderboard, surpassing ByteDance's Seedance 2.0, Alibaba ATH's HappyHorse, and Google Veo with a decisive +52 Elo point improvement over the previous version.
Synchronized Audio Generation
Audio is generated simultaneously with video in a single pass. Background music, sound effects, ambient audio, and even short dialogue are created in perfect sync with on-screen action — no separate audio editing needed. Version 1.5 introduces major audio improvements for more natural and immersive sound.
Image-to-Video Only — Purpose-Built
Grok Imagine Video 1.5 is a dedicated image-to-video model, optimized specifically for animating still images. This focused design means every parameter and capability is tuned for the best possible image animation results, from preserving visual identity to generating contextually appropriate motion.
Advanced Face Accuracy & Character Consistency
Blind testing shows substantial gains in face accuracy over version 1.0. Grok Imagine Video 1.5 generates more realistic faces — including celebrity likenesses — while maintaining strong character consistency throughout video sequences, making it ideal for portrait animations and character-driven content.
Why Grok Imagine Video 1.5 Leads the Field
Grok Imagine Video 1.5 combines xAI's Aurora engine with major upgrades in audio quality, photorealism, temporal coherence, and prompt adherence — delivering the highest quality image-to-video generation available today.
Full Feature Set of Grok Imagine Video 1.5
xAI's most advanced image-to-video model — Aurora engine physics, native synchronized audio, and the #1 ranking on the Arena leaderboard.
Image-to-Video Animation
Upload any still image — portrait, product photo, illustration, or concept art — and Grok Imagine Video 1.5 animates it with realistic motion and contextually appropriate action. The output aspect ratio defaults to the input image's native aspect ratio when set to auto.
Native Synchronized Audio
Audio is co-generated with video in a single pass. Background music, ambient sounds, sound effects, and dialogue are all synchronized to on-screen action. Influence audio by mentioning sound in your prompt or using the AUDIO: section for explicit audio direction.
480p and 720p Resolution
Choose between 480p for faster generation and lower cost, or 720p for standard definition quality. The resolution parameter gives you control over output quality and generation speed to match your project requirements.
1–15 Second Duration
Generate videos from 1 to 15 seconds long. Shorter clips (5–8 seconds) are more stable and artifact-free, while longer clips up to 15 seconds work well for narrative sequences. Choose the duration that fits your platform and creative vision.
Flexible Aspect Ratios
Support for auto (matches input image), 16:9, 9:16, 1:1, 4:3, 3:4, 3:2, and 2:3 aspect ratios. Match your output to any platform — YouTube widescreen, TikTok portrait, Instagram square, or cinematic formats.
Aurora Physics Engine
Built on xAI's proprietary Aurora engine, Grok Imagine Video 1.5 models real-world physics — gravity, momentum, collisions, fluid dynamics, and cloth behavior — for visually convincing and physically grounded animation results.
Cinematic Camera Control
Specify camera movements directly in your prompt: pan, tilt, zoom, dolly, tracking, orbit, aerial, handheld, and slow push-in. The model understands standard cinematic camera language and interprets directorial instructions with precision.
Multi-Beat Action Sequences
Grok Imagine Video 1.5 handles multi-beat sequences well. List actions in order in your prompt — the athlete crouches, then explodes forward, then the crowd erupts — and the model generates coherent multi-action sequences with temporal consistency.
