Best instruction for keeping all Adobe Firefly video content within the frame?

I've got a still image of a character on a pure white background. I was hoping to animate the character in such a way that all of the content remains within frame, and that the background remains white - for compositing purposes in After Effects. Any prompt suggestions to achieve both of those requirements?

Thanks for sharing the images. I tried using these images as keyframes and changed the background to white of the last keyframe. 

 

Let us know if this helps.

Hi 304angstroms!

Thanks for writing in. You can try prompt: Animate a still character on a pure white background. Ensure the character remains fully within frame throughout the animation. Keep the background completely white.

Use the word “Stay in Frame.” Please note that Firefly doesn't do negative prompting by the word in front of it. So, using "not [X]", "no [X]", and "without [X]" does not work.  It ignores the negation word and adds to the image the thing you are trying to avoid.

 

Let us know if you have any questions.

Hi Kartika! Thanks for the reply. I did not know that about negative prompting. Good to know.

 

So this half-worked. The character did remain in frame, but the background keeps inverting to black midway through. This has happened a number of times. Claude had suggested the following:

“clean white background for compositing"

“pure white background for video compositing”

but neither of those worked either.

 

I've attached the first frame (white bg) and the last frame (black bg) just as an example. The animation is very cool, but I'm shooting for those specifics.
