Grok Imagine 1.5 Tips
- • Grok Imagine 1.5 generates 720p at 24fps with clips up to 15 seconds — keep action complexity proportional to duration
- • Audio is generated in the same pass — use an explicit "Sound:" section and put exact dialogue in quotes for lip-sync
- • For multi-shot sequences, use "cut to" or "camera switch" as transition cues between shots
- • Build longer narratives by chaining extensions — Grok continues from the final frame, preserving motion, lighting, and character position
- • Front-load key actions: the model renders actions described early in the prompt early in the clip
- • Compose scene descriptions appropriate to your aspect ratio (16:9 cinematic, 9:16 vertical)
Frequently Asked Questions
What is Grok Imagine 1.5?
Grok Imagine 1.5 is xAI's latest video generation model (released May 2026). It produces cinema-quality 720p clips at 24fps, up to 15 seconds long, with native synchronized audio — and debuted at #1 on the Image-to-Video Arena leaderboard, ahead of Seedance and Veo.
What's new in Grok Imagine 1.5 vs 1.0?
Version 1.5 extends maximum clip duration from 10 to 15 seconds, upgrades output to 720p, significantly improves lip-sync accuracy, and adds video extension — continuing a new clip from the final frame of the previous one so you can chain shots into longer sequences.
Can Grok Imagine 1.5 create multi-shot sequences?
Yes, two ways. Within a single prompt, use "cut to" or "camera switch" as transition cues to describe multiple shots. For longer narratives, use the extension feature: select the final frame of a generated clip and instruct the model to continue from that exact point, preserving motion continuity, character positioning, and lighting.
Does it generate audio and dialogue?
Yes! Grok Imagine 1.5 generates audio in the same pass as the video: lip-synced character dialogue, ambient environment sound, synchronized sound effects, and background music. Put exact dialogue lines in quotes and add an explicit "Sound:" section in your prompt for best results.
What aspect ratios are supported?
Grok Imagine 1.5 supports 7 aspect ratios including 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3. For image-to-video, the output defaults to the input image's aspect ratio.
