I saw an item for sale on Ali Express's video and I thought "Wow, they hired some really attractive actors to pitch their little gadget." 30 seconds in, I realized they used GenAI. Not because it looked AI, but because the production values looked too high and professional for the item. I would get in on this if you sell anything online.
They can even combine the models, create the presenters with nano banana and then use that as the reference for a video model and paste in your product
One thing I notice is that the voices in video AI are absolute hogwash. Voice AI is great, video AI is great, but AI videos where humans speak give me the feel of really poorly dubbed foreign TV - the timing is not quite right and the facial expressions don’t always match up with the words being spoken.
