About Grok Video on Vivideo
Grok Video, from xAI's Grok Imagine, is a video generation model with native audio and support for short, expressive clips. As an AI video generator, Grok is known for lively output and fast turnarounds straight from a prompt.
Natively, Grok Imagine is gated behind X Premium and the Grok app. On Vivideo you can use Grok video online without an X subscription — Grok is one of 30+ AI video models on a single plan. Run Grok text-to-video from a prompt or Grok image-to-video from a still, and switch models per shot.
People search "Grok Imagine API" and how much a Grok video costs in credits. On Vivideo, Grok is included in one subscription rather than metered per clip, so you can generate Grok videos without tracking credits.
Grok is quick to prompt. A short, punchy Grok video prompt returns expressive, audio-synced motion — handy for reactions, social clips and fast creative ideas.
Grok has limits: native clips are short (about 6–15 seconds) and top out at 720p. For longer or higher-res pieces, Vivideo chains Grok shots — or switches to Sora 2, Veo 3.1 and others — into finished videos up to 10 minutes.
Is Grok video free? You can try the Grok video generator free on Vivideo with daily generations, no X Premium and no xAI account. A small upgrade unlocks watermark-free exports.
