Grok Imagine Video 1.5 overview

A source-image-first video model where sound can be part of the prompt

Grok Imagine Video 1.5 starts from a still image and extends its visual logic through time. The prompt should explain what moves, how the camera behaves, what the subject says or hears, and which details from the starting frame must remain recognizable.

01

Motion that respects the frame

Animate a face, product, vehicle, environment, or stylized character while carrying forward the original composition and lighting.

02

Audio tied to the action

Describe footsteps, rain, room tone, mechanical impacts, crowd ambience, dialogue, or a small vocal reaction in the same video brief.

03

Fast creative iteration

Use the Fast variant for testing several motion directions, hooks, camera moves, and social formats before refining the strongest idea.

Official Grok Imagine Video 1.5 output

Watch motion and sound as one result

These clips are served from the official xAI release page. They demonstrate the model's synchronized audio and motion rather than unrelated footage from an earlier Grok Imagine version.

Official xAI example

Cinematic movement with scene ambience

Evaluate whether character movement, fabric, camera timing, environmental sound, and the physical space feel like parts of the same shot.

Official xAI example

Human performance, speech, and room tone

Look beyond lip movement: useful output also needs stable facial identity, natural micro-motion, consistent lighting, and audio that lands at the right moment.

Creative and marketing video cases

Six Grok Imagine Video 1.5 demos worth producing

Each case begins with a deliberately designed source frame. The motion prompt then adds action, camera direction, timing, sound, and speech without asking the model to redesign the entire visual.

Vertical social video

A natural spoken hook with the product in frame

Test facial stability, hand movement, readable packaging, conversational delivery, and bathroom ambience in one short creator-style ad.

View source-image and video prompts

Source image: Vertical candid smartphone frame of a fictional skincare creator in a warm modern bathroom, holding a clearly visible fictional serum bottle beside her face, natural skin texture, uncluttered background, package label facing camera, no real brand.

Video: Natural handheld selfie movement. She raises the serum slightly, smiles, and says: “This is the one step I stopped skipping.” Keep her face and the bottle label stable and sharp. Add quiet bathroom room tone, a soft bottle-cap click, and restrained conversational delivery. No music, no cuts.

Character storytelling

A two-line scene where atmosphere carries the emotion

Use a controlled performance, moving reflections, carriage vibration, and synchronized dialogue instead of exaggerated action.

View source-image and video prompts

Source image: Cinematic two-shot inside a nearly empty night train, fictional woman by the window and fictional man across the aisle, rain reflections, deep blue and amber practical light, realistic film still, no text.

Video: The train sways gently as rain and city reflections move across the window. The man asks quietly, “Are you getting off at the last stop?” She waits one beat, looks outside, and answers, “Not tonight.” Preserve both faces and wardrobe. Add subtle rail rhythm, carriage hum, rain, and restrained natural voices.

Physics and sound design

A product shot built around condensation, ice, and impact

Let the packaging remain fixed while motion and native sound create the tactile payoff.

View source-image and video prompts

Source image: Premium fictional citrus drink can standing on wet black stone, exact invented label facing forward, cut citrus, clear ice cubes, dark studio with cyan and warm coral rim light, no real logos.

Video: The camera pushes in slowly. An ice cube drops beside the can, splashing water toward camera; condensation beads merge and slide down the aluminum. The can does not move and the label remains readable. Add a sharp ice impact, crisp splash, light carbonation hiss, and clean studio room tone. End on the unchanged hero composition.

Animation and ambience

A handcrafted loop that feels alive at thumbnail size

Test stylized motion, layered environmental sound, and a clean repeatable action for social content.

View source-image and video prompts

Source image: Whimsical handcrafted miniature city at dawn made from painted wood, paper, and warm practical lights, tiny bakery, tram, trees, and rooftops, tactile stop-motion style, no text.

Video: A tiny tram enters from the left as shop lights turn on one by one. A baker opens the window, steam rises, paper birds lift from a roof, and the camera makes a slow diagonal push. Add miniature wheel clicks, a small bell, distant birds, and gentle morning city ambience. Preserve the handmade materials and scale.

Bold and shareable

A fast visual twist designed for the first three seconds

Use Grok's playful visual character for a surprising but controlled transformation rather than generic cinematic footage.

View source-image and video prompts

Source image: Symmetrical wide office meeting room with six fictional coworkers frozen around a table, ordinary corporate lighting, realistic photography, one small red emergency button at the center, no brands.

Video: A hand presses the red button. On the click, the fluorescent lights snap off and the room transforms into a zero-gravity disco: papers and coffee droplets float upward while everyone remains recognizable and reacts naturally. Camera stays locked. Add button click, electrical power-down, rising synth sting, surprised gasps, and floating-object sounds. End before any reset.

Emotion and creature audio

A non-human character that communicates without speech

Combine subtle eye movement, breath, environmental response, and a distinctive sound identity before continuing into a longer story.

View source-image and video prompts

Source image: Cinematic close-up of an original small moss-covered forest guardian with luminous amber eyes, sitting beneath giant wet leaves after rain, highly detailed practical-creature aesthetic, no familiar franchise design.

Video: The creature hears something off-screen, lifts its head, blinks slowly, and takes one cautious step toward camera. Tiny droplets fall from its moss as nearby leaves move. It makes a soft questioning chirp, followed by a distant answering call from the forest. Slow push-in, shallow depth of field, preserve anatomy and facial design.

How to prompt Grok Imagine Video 1.5

Separate what the image defines from what the video must do

The still image should already contain the approved identity, product, environment, composition, and lighting. The video prompt should direct temporal behavior: action, camera, pacing, dialogue, ambience, effects, and the details that must not drift.

01

Lock the visual anchors

Name the face, product, label, wardrobe, room geometry, or character design that must remain unchanged.

02

Write the timeline

Describe the opening state, action, reaction, camera move, and final composition in chronological order.

03

Direct the soundtrack

Specify exact dialogue, vocal tone, ambience, Foley, impact sounds, music, and moments that should remain quiet.

Do not overload a short clip

One controlled action with one clear audio idea is usually more reusable than several cuts, speakers, transformations, and camera moves competing inside the same generation.

Practical model selection

When Grok Imagine Video 1.5 is a strong fit

Use it for

  • animating approved product and character keyframes;
  • short clips that need native ambience or Foley;
  • spoken social hooks and compact dialogue scenes;
  • fast iterations on movement and camera direction;
  • bold, playful, stylized, or meme-ready concepts;
  • creative shots that continue into a larger edit.

Review carefully when

  • packaging text must remain perfectly readable;
  • several people speak in rapid succession;
  • the scene contains complex hand-object interaction;
  • long causal sequences depend on exact timing;
  • the final audio needs detailed manual mixing;
  • many shots must preserve strict continuity.
