Utilise the technology of generative fill to power a tool that allows you to create frames between two images.
For example: if I have an image of someone looking left and the same person looking forward, you could create 'frames' to transition between these two images (perhaps specifying the number of frames between). Imagine the blend tool in Illustrator, but for photos + using AI.
These frames could then be brought into Premiere Pro or After Effects to create lifelike transitions.
For my own purposes, I would use such a tool in this context: I have two videos of the same person but in different settings. The person is looking in different directions. I would cut the person out and create frames between them to transition them. When brought back into the full video, it would appear as though footage of the person has remained consistent, while completely changing their activity/location.
