Grok Imagine 1.5 Tips
- • Grok Imagine 1.5 generates clips up to 15 seconds, now with native 1080p: keep action complexity proportional to duration
- • Text-to-video works without a starting image (since July 31, 2026): describe the subject and setting fully when you have no image
- • With image references (up to 14), say what each one locks, such as the face, the product or the location, and write only the motion and camera for the rest
- • 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
- • In the API, tag references as <IMAGE_0>, <IMAGE_1> and preset voices as <AUDIO_0>, in upload order
- • Grok Imagine 1.5 Lite ($0.02/s) handles simple text-to-video and image-to-video with lip-synced speech; use full 1.5 ($0.08/s) for references, voices, pinned frames or native 1080p
- • 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)

Atmospheric Mood Piece
CinematicSlow, light-led work with minimal action.
[SETTING] in [CONDITIONS]. The only motion is [WHAT MOVES — e.g. rain running down the window and the slow flicker of a neon sign outside].

Duration: [SECONDS] seconds.
Social Clip
SocialVertical, fast, built to hold attention in a feed.
A vertical [SECONDS]-second clip for [PLATFORM]. [SUBJECT] [ACTION] in [SETTING]. Opens on [STRONG FIRST FRAME] — no slow build. [WHAT KEEPS IT MOVING]. Camera: [DYNAMIC FRAMING]. Lighting: [BRIGHT/HIGH-CONTRAST]. Audio: [SOUND OR MUSIC]. Keep the subject centred and clear of the bottom third.
Reference Cast with Preset Voice

Popular Grok Imagine 1.5 Use Cases
Where 1.5's longer clips, lip-sync, native audio, and references make the biggest difference.
Talking-head & dialogue scenes
Improved lip-sync makes 1.5 strong for character monologues, two-person conversations, and narration. Put exact lines in quotes for clean mouth movement.
Social video (Reels, Shorts, TikTok)
9:16 vertical clips up to 15s with native audio — ready-to-post UGC, hooks, and creator content without a separate sound pass.
Multi-shot story sequences
Chain extensions from the final frame to build longer narratives, or use "cut to" cues inside a single prompt for multiple shots.
Product & ad spots
Cinematic 1080p product showcases and short ad teasers with camera moves, lighting direction, and synchronized music or SFX.
Image-to-video animation
Animate a still into motion — the output defaults to the input image's aspect ratio, preserving your framing and composition.
ASMR & sound-design clips
Native audio generated alongside the video makes 1.5 a fit for ambient, ASMR, and diegetic-sound pieces — describe the soundscape explicitly.
Frequently Asked Questions
What is Grok Imagine 1.5?
Grok Imagine 1.5 is xAI's latest video generation model. It was announced as a preview on May 31, 2026 and became generally available on June 16, 2026. It makes clips up to 15 seconds long with native synchronized audio, and since July 31, 2026 supports text-to-video and native 1080p. It debuted at #1 on the Image-to-Video Arena leaderboard, ahead of Seedance and Veo.
What's new in the July 31, 2026 Grok Imagine 1.5 update?
xAI added text-to-video (no starting image needed), native 1080p for text-to-video and image-to-video, image references (up to seven per generation to lock faces, products or locations) and voice references that keep the same voice across scenes. Text-to-video and 1080p are generally available on grok.com/imagine, iOS and Android. Image and voice references started with US SuperGrok Heavy and SuperGrok Plus users and rolled out to other tiers; in the API, image references are live and voice references are available on request.
What's new in Grok Imagine 1.5 vs 1.0?
Version 1.5 extends maximum clip duration from 10 to 15 seconds, outputs 720p at 24fps at launch (native 1080p followed on July 31, 2026), 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?
xAI's API lists 9 aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9 and 5:2. For image-to-video, the output always matches the input image's aspect ratio.
