After seeing this joke over in the jokes thread,
I had to give that idea to Grok and Sora2.
The first attempt in grok didn’t work well, it assumed I was talking about submachine guns.
Grok prompt
Make a video based on this idea and music: “It was an itsy bitsy teeny weeny light grey anti-sub machiney”
(that’s as in anti-submarine warfare)
Then tried that same prompt in Sora2 but the having the lyrics in quotes was rejected as being 3rd party content.
Prompt
First attempt:
Make a video based on this idea and music: “It was an itsy bitsy teeny weeny light grey anti-sub machiney”
(that’s as in anti-submarine warfare)
That one got moderated early in the generation process as a 3rd party content violation.
This fixed prompt worked, and it still got the right idea that it should sing that, woot.
