I am pretty sure that you can ask to the free Gemini online to give you the text of a description video!
https://gemini.google.com/app

Then input the result in any convert Text to voice... or maybe Gemini it self who knows ?

I have yet made this (nothing to do with voice...
Ask Gemini to give me a 5 prompts about any subject wanted (very few word from me) that you want but with technical term of Midjourney

and then you put the result inside Bing ...or Wizcom! ;)

the Ai for text to voice! ;)
https://www.naturalreaders.com/online/ very good but not free for more 20 items!

A free one https://ttsmaker.com

The Vizcom result is more poetic! :)


The Bing Result! More near the Gemini description!
