Words are the whole brief
Grok Imagine Video is xAI's text-to-video line. Nothing has to exist first. You write the shot and it renders, one to fifteen seconds, up to 720p. Attach up to eight reference images when something has to stay exact.
The cheaper door into the family
Every length and size on this line costs less than the same cell on 1.5. It stops at 720p, and that is the trade. Draft the idea here. Move it up when a take earns the higher tier.
When the frame already exists
Grok Imagine 1.5 animates a still you attach, and it requires one. Grok Imagine image renders that still up to 2K. Three doors, one wallet, one models roster.
What it will not do
Grok Imagine Video gives you no audio control. The composer shows no sound switch for this model, so there is nothing to steer. There is no 1080p rung either. Plan the audio in your editor, or take the shot to Veo 3.1 when it needs sound written with the picture.
