Some typical clips: - 5 s text to video at 480p — 120 credits. The cheapest way to test a prompt. - 5 s image to video at 720p — 213 credits (210 + 3 for the start image). - 10 s text to video at 720p — 420 credits. - 5 s reference to video at 720p with 7 images — 231 credits. - 15 s text to video at 1080p — 1,125 credits. ### Prompting Grok Imagine 1.5 for motion and sound xAI describes 1.5 as an image-to-video model first: give it a start frame, describe the motion, and choose resolution and duration [1]. Keep one clear action per clip, name the camera move (push-in, pan, handheld), and describe the sounds you want — rain, engine roar, a crowd — because the audio is generated with the video. Put spoken lines in quotes and say who speaks. ### Grok Imagine 1.5 on Kenerate vs xAI's apps Kenerate runs the API model, grok-imagine-video-1.5, for text, image and reference to video [2]. xAI's Grok apps also offer Video 1.5 Fast, which xAI says makes a 6-second 720p clip in about 25 seconds instead of 40-plus [1][3], along with projects and library search. If you want Grok Imagine next to Seedance, Kling and Wan on one credit balance with no subscription, use Kenerate; if you live in the Grok app, that's where the Fast build is.

A: Grok Imagine Video 1.5 is xAI's AI video model and the successor to Grok Imagine 1.0. It turns a text prompt, a start image or reference images into clips of up to 15 seconds, with sound effects, ambience and dialogue generated in the same pass. Its API name is grok-imagine-video-1.5. Q: When was Grok Imagine 1.5 released? A: A preview appeared at the end of May 2026, and xAI made Grok Imagine Video 1.5 generally available on its Imagine API on 16 June 2026, retiring the preview. At the same time xAI rolled out a faster Video 1.5 Fast build in the Grok web, iOS and Android apps. Q: Is Grok Imagine 1.5 free? A: Not on Kenerate's free plan — video needs a paid plan, which means any one-time credit pack (from $15 for 1,300 credits, no subscription). New accounts get 25 credits for images. In xAI's own Grok apps, free and paid limits are set by xAI; check grok.com for its current terms. Q: How do I use Grok Imagine 1.5 without SuperGrok? A: Open Kenerate's video studio at /app/video, pick Grok Imagine 1.5, add a prompt (and a start image or references if you want), choose length and resolution, and generate. You pay per clip in credits — no Grok subscription and no xAI API key. Q: How much does Grok Imagine 1.5 cost per second? A: On Kenerate it's 24 credits a second at 480p, 42 at 720p and 75 at 1080p, plus 3 credits for each input image. A 5-second 480p text-to-video clip costs 120 credits, a 5-second 720p image-to-video clip 213, and a full 15-second 1080p clip 1,125. Q: Grok Imagine vs Grok Imagine 1.5 — what's the difference? A: 1.5 makes any length from 1 to 15 seconds and goes up to 1080p; 1.0 offers 6 or 10 seconds at 480p or 720p. xAI says 1.5 has steadier motion and physics and clearer, better-synced sound. 1.0 is cheaper (15 credits a second on Kenerate) and is the one that can edit and extend an existing clip. Q: How long can Grok Imagine 1.5 videos be? A: 1 to 15 seconds per clip, in whole seconds. For longer pieces, generate several clips — using a frame from the end of one as the start image of the next keeps the look consistent — and join them in an editor. Q: Does Grok Imagine 1.5 make sound? A: Yes. xAI generates sound effects, ambience and dialogue in the same pass as the video, so the audio follows the action. Describe the sounds in your prompt and put any spoken line in quotes. Q: Can Grok Imagine 1.5 do 1080p? A: Yes, for text to video and image to video. Reference to video, where you give it up to 7 images, is limited to 480p or 720p. 1080p costs 75 credits a second on Kenerate, so draft at 480p first. Q: What is the Grok Imagine 1.5 API pricing? A: Kenerate prices Grok Imagine 1.5 from the provider's per-second rate of $0.08 at 480p, $0.14 at 720p and $0.25 at 1080p, plus $0.01 per input image, at 300 credits per dollar. xAI's own API console shows its current list price; you don't need an API key to use it on Kenerate. ## Related pages - Grok video generator: https://kenerateai.com/grok-imagine-video-generator - Grok Imagine image models: https://kenerateai.com/model/grok-imagine - Seedance 2.0: https://kenerateai.com/models/bytedance/seedance-2-0 - Kling 3.0: https://kenerateai.com/models/kwaivgi/kling-v3-0 - Reference to video AI: https://kenerateai.com/reference-to-video-ai - All AI video models: https://kenerateai.com/ai-video-models ## Sources - Grok Imagine Video 1.5 — xAI news (16 June 2026): https://x.ai/news/grok-imagine-video-1-5 - xAI Imagine API: https://x.ai/api/imagine - Grok Imagine Video 1.5 general availability — GIGAZINE (18 June 2026): https://gigazine.net/news/20260618-grok-imagine-video-1-5/ - Creating with Grok Imagine 1.5 — Runway Help Center: https://help.runwayml.com/hc/en-us/articles/53995376768147-Creating-with-Grok-Imagine-1-5
