Why reAPI
Image-to-video that holds identity
Grok Imagine Video 1.5 animates from one reference image while keeping face, body, and silhouette consistent across the clip. Real skin texture and natural motion, no morphing or clones — built for believable live-action results.
Native synchronized audio
Grok Imagine Video 1.5 generates video and audio together in a single workflow — dialogue, sound effects, ambient room tone, and music — so you skip the separate audio-generation and post-production steps entirely.
Simple per-second pricing
Grok Imagine Video 1.5 bills per second by resolution, with no subscription. The cost scales linearly with the duration parameter, and failed jobs refund automatically — you only pay for clips that succeed.
