Grok Imagine Video 1.5 Preview: Image to Video Online
Bottom line
xAI's image animator with per-second duration control from 1 to 15 seconds — VdoBloom's top-rated at 5.0. Upload a starting frame, choose Grok Imagine Video 1.5 Preview in the Image to Video tool, and animate it on VdoBloom — the credit price appears before every generation.
Grok Imagine Video 1.5 Preview, from xAI, animates a single uploaded image, and its standout spec is duration granularity: any whole second from 1 to 15, rather than the two or three fixed lengths most image-to-video models offer. That precision matters for cutting to a beat or fitting an exact slot in an edit without trimming or padding. On VdoBloom it's an image-to-video model only — there's no text-to-video mode here, you need a starting image.
Framing covers seven aspect ratios (1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3), including both camera-native photo orientations most models skip, rendered at 480p, 720p, or 1080p. It's VdoBloom's highest-rated model at 5.0, and carries a HOT content label — xAI's generally permissive filtering approach, more flexible than the strictly moderated Gemini Omni models, though platform rules on illegal or explicit content still apply.
Pricing scales with both duration and quality, so a short 480p test and a longer 1080p delivery are priced very differently — VdoBloom shows the exact credit cost for your settings before you generate, and refunds automatically if a render fails.
What it costs on VdoBloom
Price scales with both duration and quality tier. At 480p, cost runs from 2 credits at 1 second up to 23 credits at 15 seconds. At 720p, the same range is 3 to 45 credits. At 1080p, it's 5 to 75 credits. A practical worked example: a 5-second 720p clip costs 15 credits, while a 10-second 1080p clip costs 50 credits — resolution has a much bigger effect on price than on most other video models, since 1080p costs roughly 5x the 480p rate at the same duration, not a flat premium.
Common problems and how to avoid them
Online discussions about this model report inconsistency between runs and moderation that feels stricter than expected for prompts that seem tame. Neither is something VdoBloom can override — the underlying xAI model's behavior and filtering are provider-side. What VdoBloom controls is the economics of testing: since cost is shown before you generate and scales down sharply at lower duration and resolution, the practical way to deal with inconsistency is to iterate cheaply (1-2 seconds at 480p costs only a few credits) before spending on a longer, higher-resolution final render, and a failed generation is refunded automatically rather than silently charged.
What creators use Grok Imagine Video 1.5 Preview for
- Cutting a clip to an exact beat count for a music-synced edit, since duration is selectable to the second.
- Animating photography in its native 3:2 or 2:3 orientation instead of forcing a crop to 16:9.
- Drafting motion concepts cheaply at 480p, then rerunning only the keepers at 1080p.
- Producing short 1-3 second loop segments for a multi-clip sequence.

Frequently asked questions
What does Grok Imagine Video 1.5 Preview cost?
It scales with both duration and quality. At 480p: 1s = 2 credits, 5s = 8, 10s = 15, 15s = 23. At 720p: 1s = 3, 5s = 15, 10s = 30, 15s = 45. At 1080p: 1s = 5, 5s = 25, 10s = 50, 15s = 75. The exact price for your settings is shown before you generate.
Is Grok Imagine Video free on VdoBloom?
New accounts start with 10 free credits, which covers a short clip outright — a 1-second 480p render is 2 credits, so you can test the model multiple times before buying a pack. Longer, higher-resolution renders cost proportionally more.
Can I make a video longer than a few seconds?
Yes — on VdoBloom, duration is selectable to the exact second anywhere from 1 to 15 seconds. If you've seen shorter limits elsewhere, that's a constraint of a different product, not this model as offered here.
Why do people say Grok Imagine's video generation has gotten more moderated?
This model carries a HOT content label on VdoBloom — the platform's more permissive filtering tier, in line with xAI's generally flexible approach — but that doesn't mean unrestricted. Explicit and clearly prohibited content is still blocked, and provider-side moderation on any model can tighten over time without VdoBloom controlling that.
Does Grok Imagine Video support video-to-video?
No, not this model. It's image-to-video only — you upload a single starting image and a prompt describing the motion; it doesn't accept an existing video clip as input.
What resolutions and aspect ratios are available?
Three quality tiers — 480p, 720p, 1080p — and seven aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3. The 3:2 and 2:3 ratios match common camera orientations that many video models don't offer natively.
What is the "Preview" in the name?
It marks this as the early-access build of xAI's Grok Imagine Video 1.5 generation as offered on VdoBloom. It already holds VdoBloom's top 5.0 community rating, but behavior may continue to be refined by xAI over time.
My animation changes unexpectedly when I regenerate — why?
Image-to-video models can interpret the same prompt differently between runs, especially for motion that isn't explicitly described. Being specific about what should move versus stay still helps consistency. Since VdoBloom shows the credit cost upfront and refunds outright failures, testing a cheap 480p/1-2 second version before committing to a longer, pricier render is the low-cost way to lock in a direction.
How do I use Grok Imagine Video on VdoBloom?
Open the Image to Video tab, select Grok Imagine Video 1.5 Preview, upload your starting image, write a prompt describing the motion, choose duration (1-15s) and quality (480p/720p/1080p), review the credit cost, and generate.
