Lean Production with Grok Imagine Video 1.5 Lite

Grok Imagine Video 1.5 Lite turns prompts or starting images into 1 to 15 second clips with native audio, lip synced speech, seven text to video aspect ratios, three resolution tiers up to upscaled 1080p, and transparent Atlas Cloud access at $0.02 per generated second through one API.

Two Creation Paths in Grok Imagine Video 1.5 Lite

Grok Imagine Video 1.5 Lite supports both text to video and image to video generation. Start from a written scene or provide one image as the opening frame, then direct the action with a prompt. Both routes produce clips within the same model family. This flexibility suits teams moving from rapid concepts to animated product stills without switching video providers.

One to Fifteen Seconds of Story

Choose any clip length from 1 to 15 seconds rather than working around a single fixed duration. Short runs can test an idea economically, while longer generations give an action or spoken beat more room to develop. The adjustable window helps developers match output length more precisely to social posts, product moments, and compact narrative scenes.

Three Resolution Tiers

Select 480p, 720p, or 1080p output for each generation, with 1080p delivered by upscaling from 720p. Use lower tiers for fast iteration and reserve the largest frame size for polished previews or final delivery. Clear resolution choices let a production balance visual detail, downstream bandwidth, and cost according to where each clip will appear in practice.

Native Audio with Lip Synced Speech

Native audio arrives with every generated clip, and spoken lines can be synchronized to visible lip movement. Describe dialogue, ambient sound, music, or effects alongside the scene so picture and sound are created together. For character exchanges, music driven edits, and atmosphere rich storytelling, this combined output reduces the need to assemble a separate audio pass.

Seven Formats from One Prompt

Text to video requests can render in seven aspect ratios: 16:9, 4:3, 3:2, 1:1, 2:3, 3:4, and 9:16. Set the format before generation to match landscape, square, or vertical delivery. Image to video follows the supplied starting frame instead, helping the motion preserve the composition already chosen for that source across common digital publishing workflows.

Grok Imagine Video 1.5 Lite at $0.02 per Second

At a standard price of $0.02 per generated second, Grok Imagine Video 1.5 Lite is built for cost conscious video workflows. Usage follows transparent per second billing, so short tests and longer renders remain easy to forecast. Atlas Cloud places text and image generation behind one API, simplifying integration for products that need repeated clip production.

One Prompt, Three Visions: Grok Imagine Video 1.5 Lite

See how Grok Imagine Video 1.5 Lite and two Atlas Cloud alternatives interpret identical cinematic prompts across realistic action and stylized fantasy.

Prompt

An 8–10 second miniature action narrative set backstage at a ballet premiere: a ballerina bends to tie her pointe shoe when a scarlet satin ribbon suddenly springs to life and darts away. Begin with an extreme macro close-up of the shoe tip, taut laces, and shimmering silk fibers; push rapidly forward as the ribbon slips free, then drop into a floor-level tracking shot racing beside it as it coils around costume racks, threads through rotating scenery wheels, snaps beneath curtains, and whips loose feathers into swirling vortices. The dancer pursues without breaking ballet form—rapid chaîné turns, long crossing steps, a precise leap over a rolling prop, then a seamless knee-low glide beneath hanging costumes—while the camera maintains convincing occlusion tracking through racks and stage machinery. Whip-pan into a cold blue-gray side corridor for a lateral wide shot of her final accelerating sequence; one second before the curtain rises, she leaps and pins the ribbon beneath her pointe shoe. Twist: the ribbon instantly spirals up her arm like a living partner. Follow closely from behind as she surges through the opening curtain onto an amber-gold stage, where the ribbon unfurls into an elegant translucent virtual dance partner and joins her first turn. Dramatic lighting transition from cool cyan-gray backstage shadows to radiant amber-gold footlights, with scarlet red continuously guiding the composition. Hand-painted gouache animation blended with photorealistic silk texture, expressive brushwork, fluid flexible-body physics, continuous graceful motion, stable character design, intricate cloth collisions, no slow motion, no static filler. Audio: urgent pointe-shoe taps, rustling satin, rattling scenery wheels, feathers fluttering, rising orchestral strings, then a bright musical удар as the curtain opens; no dialogue, no captions, no text, no interface elements. 16:9 aspect ratio.

Prompt

An 8–10 second hyper-realistic cinematic macro sequence inside a traditional Venetian glassblowing workshop at dawn: a sweat-sheened female glassblower continuously rotates a long blowpipe beside a roaring furnace, inflating a molten orange-red glass gather into a transparent firebird with delicate amber wings and cobalt-blue accents. Begin with an extreme macro close-up of the viscous glass breathing, stretching, and refracting the flames; rapidly dolly out into an over-the-shoulder tracking shot as the living glass bird suddenly breaks free, flaps through shimmering heat haze, skims past hanging goblets, and knocks down a strand of tiny glass beads that scatter, bounce, spin, and chime with physically accurate collisions. She reacts instantly, raising long steel tongs and chasing its path; whip-pan into a fast, seamless orbit around the furnace as the firebird completes one fluid circuit, its transparent body bending reflections and warm light without changing design. Finish from a dramatic low angle as the bird voluntarily lands on the tong tips, folds its wings, and crystallizes into an exquisite miniature ornament while she steadies it, breathless and smiling. Warm furnace fire as the key light, indigo dawn rim light through the window, controlled amber, cobalt-blue, and crystal-clear highlights, realistic heat distortion, molten-glass deformation, reflections, refractions, sparks, sweat, and continuous subject identity. Crisp high-speed motion with natural motion blur, no slow motion, no static filler, no cuts that break continuity. Immersive synchronized audio: furnace roar, rhythmic glassblower breaths, wing-like crystalline ringing, swinging goblets, cascading bead chimes, metal-tong click, and a brief musical shimmer at the final transformation. No screens, software interfaces, dashboards, progress bars, charts, captions, subtitles, logos, watermarks, extra limbs, warped hands, duplicated tools, inconsistent bird anatomy, opaque glass, plastic-looking surfaces, floating objects without physical interaction, or flickering identities. 16:9 aspect ratio.

Grok Imagine Video 1.5 Lite FAQ

Grok Imagine Video 1.5 Lite is xAI's lowest-cost model in the Video 1.5 family for generating short clips from text or a starting image. It produces videos lasting 1 to 15 seconds with native audio and lip-synced speech.

Turn a written prompt into a complete video, or animate an existing image as the opening frame of a new scene. Both generation modes can produce synchronized dialogue, ambient sound, and effects in the same pass.

Choose the text-to-video endpoint for prompt-only generation or the image-to-video endpoint when you have a starting frame. Enter a prompt, select the duration and resolution, then submit the request. For image animation, also provide the required source image.

Yes, the model generates audio natively alongside the visuals and supports lip-synced speech. Describe the intended dialogue, ambience, and sound effects in your prompt so they can be incorporated into the scene.

Clips can run from 1 to 15 seconds and use 480p, 720p, or 1080p output. The 1080p option is upscaled from 720p rather than rendered at native 1080p.

Your supplied image becomes the first frame, while the prompt directs subsequent motion, camera behavior, and audio. The generated clip follows the aspect ratio of that source image.

Atlas Cloud lists a standard price of $0.02 per generated second for both the text-to-video and image-to-video endpoints. Billing scales with the requested output duration under pay-as-you-go pricing.

Lite prioritizes lower-cost text-to-video and image-to-video generation for simpler production needs. The full Video 1.5 model is intended for workflows requiring reference images, voice references, pinned frames, or native 1080p output. Choose Lite when cost-efficient iteration matters more than those advanced controls.
