So a fun 'cheat' I've found with Grok Imagine is that if you create an image first, then hit the little 'play' button in the lower right hand corner of it to try to convert it into a video, actually has a pretty good chance of working the first time. IF you do it a few more times though I find the moderator catches on and stops all consecutive requests. But rendering a new picture and doing it again throws the moderator for a loop all over again. So you MIGHT get one or two great ones. Like this!
