Im having a similar issue with a picture of my baby sitting outside on grass. I copied a prompt from their "How to" article "Cinematic closeup. The lighting is cinematic, gorgeous, and soft, with beautiful, strong backlight and lens flare. The color grade is warm, sun-drenched, and sunlit morning." modified it just a bit and is telling me that it doesn't meet their guidelines. I just wanted to test this. 😞
Thanks for reaching out. Here's the prompt: "The Chef is dancing with the skillet. He is having a lot of fun." And I included the chef image with the prompt.
Were you using that image in text to image as a composition reference or a keyframe in image to video? I was able to use that image as a composition reference and a keyframe so there might be some other problem.
What prompt were you using? Can you please include a screenshot of the full browser window with the error showing?
