xAI gives video generation seven references

xAI’s Imagine Video 1.5 now accepts up to seven reference images per generation, giving creators more anchors for characters, products, and locations. The official API documentation caps reference-led clips at 15 seconds and 720p, while text- and image-to-video generation now reaches native 1080p. For creative teams comparing the release with FLUX 3’s gated 20-second video system, the file-away detail is that controllability is becoming an explicit input budget—but consistency still needs testing on each production workflow.
