>where is your proof that it can't do more than 2 minutes for make a video

....I read the actual research paper...that's how I know. Only one of them can do minutes. The other two can only do seconds at the moment.

For Imagen Video:

video at 24 frames per second.

128 frames/24 frames per second is a 5 second video.

For Meta

16 frames which they interpolate between to create a few second video.

And then Phenaki, which can generate the longest at a few minutes.

...You clearly have no clue what you are talking about. I would suggesting doing some reading on the current state of the tech and also read the actual research papers.
