I imagine the goal isn't to produce 5 second videos. If the goal is to use firefly video to create shorts, commercials, educational videos, or full-length videos, we need a storyboard function. Currently I am not sure what the "seed" does as it doesn't provide and generation consistency.
I divided the complete story into 5 second prompts buAnd taking a screenshot of the character generated in the first video and an image upload to control the output generates an error. I would love to create a complete scene and a storyboard that locks in the main character/s output would be amazing. For now I am doing it old school.
