>does grok even let you specify the target image?
You can upload your own image and do image to video. Or you can ask Grok to gen an image first and then turn it into video. But from what I've tested grok only knows Reimu and Mokou. Every 2hu girl tries to turn into Mokou for some reason.

>can you grok the youmu turning her head above
you mean this? >>50276073
Yeah you probably can but Grok doesn't know what Youmu really looks like so it'll be some random anime girl. And everyone can do it, you can use it for free until you hit the hourly limit.
