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 and seven aspect ratios. 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.
Most image-to-video models lock you into two or three preset lengths. Grok Imagine Video 1.5 Preview, from xAI, lets you pick any whole-second duration from 1 to 15 — which sounds like a small thing until you're cutting to music and need a clip that is exactly 7 seconds, not 5 padded or 10 trimmed.
That precision extends to framing. Seven aspect ratios (1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3) cover square feeds, widescreen, vertical shorts, and both photo orientations, so your source image dictates the crop rather than the other way around. Output comes in 480p or 720p; the lower tier is genuinely useful as a fast draft pass before rerunning keepers at 720p.
This is a preview build of the 1.5 generation, and it currently holds a 5.0 rating on VdoBloom — the top mark in the directory. Generation is billed in VdoBloom credits, with the cost shown upfront before each run.
What creators use Grok Imagine Video 1.5 Preview for

- Animating photography in its native orientation using the 3:2 and 2:3 ratios most cameras actually shoot in.

Frequently asked questions
Can I set an exact clip length in Grok Imagine Video 1.5 Preview?
Yes — any whole-second duration from 1 to 15 seconds. That per-second control is unusual among image-to-video models and makes it practical to generate clips that drop straight into an edit without trimming.
Which aspect ratios and resolutions are available?
Seven ratios — 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3 — rendered at 480p or 720p. The 480p tier works well for rapid drafting, while 720p is the delivery setting.
What does the "Preview" in the name mean?
It's the early-access build of xAI's Grok Imagine Video 1.5 generation as offered on VdoBloom, so behavior may continue to be refined. It already holds a 5.0 community rating on the platform.
Will Grok Imagine Video 1.5 reject edgy prompts?
It's labeled HOT on VdoBloom, the more flexible filtering tier, consistent with xAI's generally permissive approach. Content that violates platform terms or law is still blocked, but it tolerates a wider creative range than CENSORED-tier models.
