Grok Imagine Video 1.5, Standard against Lite
Grok Imagine Video 1.5 is xAI's video model with sound in every render, in two tiers with the same controls. Both clips came from one fox prompt at 720p for six seconds. Play them together and switch which tier you hear.
Closer framing, denser fur and snow. The fox turned to the lens; footsteps are quiet.
Wider and flatter, but it follows the beat: trot, pause, head lift. Near-silent audio.

Reference to video
Tag references inside the Grok Imagine Video 1.5 prompt
Upload one to seven images, name them <IMAGE_0>, <IMAGE_1> in upload order, then tap a tag.
<IMAGE_0>Brass wind-up robotCarried into the clipBrass body, chest key, round eyes
<IMAGE_1>Library reading tableCarried into the clipGreen lamp, open book, shelves
walks with stiff clockwork steps across the oak table in , stops beside the open book, turns its head toward the lamp, then lifts one arm and pushes a page so it turns over. Warm lamplight, slow push-in camera. Ticking clockwork, soft metallic footsteps, the papery flip of the page. No text.
The page turns only in the final second and the head came back smaller: references carry identity, not exact proportions.
Image to video
What Grok Imagine Video 1.5 moved, and what it held
Your upload opens the shot and sets the frame. Tick off each line of the brief.
Read the motion prompt
The breeze from the open window grows: the sheer curtains billow inward, the sails of the model boat swell and its rigging trembles, and the loose sheets of paper on the desk lift and slide toward the edge. The camera stays fixed. Sound of wind gusts, rustling paper and distant waves. Keep the boat, desk and window exactly as in the image.
Seven frames
Grok Imagine Video 1.5 in vertical, square or widescreen
Text and reference modes take seven aspect ratios at the same price. Pick a frame to see where it fits.
9:16 Reels, Shorts, TikTok and Stories, as in the balloon clip. Same price as the other ratios.
Standard, 480p, six seconds (168 credits): clear burner roar, soft detail.
Read the vertical prompt
Vertical shot at sunrise: a striped red and yellow hot air balloon rises slowly out of a misty river valley. The burner flame flares twice and lights the inside of the envelope as the basket climbs past the camera. The roar of the burner, then calm morning birdsong. Gentle upward camera tilt following the balloon, no text.

The brief we used
Four clauses in a Grok Imagine Video 1.5 prompt
- 01
Subject and place
A red fox trots through fresh powder snow in a quiet birch forest at golden hour.
One subject, one place, one light.
- 02
Camera
The camera tracks alongside at the fox's eye level…
One move. Standard still drifted from it.
- 03
Beat
the fox pauses, lifts its head toward a sound off-screen, then keeps moving.
A pause gives six seconds a shape.
- 04
Sound
Soft crunch of footsteps in snow, a light breeze, one distant crow call. No music.
Every clip has audio, so name what you want to hear.
