I tried the video generation model in firefly

Hey @ParzivalOG 

Welcome to the community.

Your prompt includes the word 'boy".
Firefly and many of the other models will not generate anything that relates to children.

Other Common problems

• Trademarked / Copyright
• Political figures / Celebrities 
• Children (Adobe will not prompt anything with  regards to children)
• Nudity

Cheers

Nate
