Definately noticing more movement if it's in the prompt with the newer lightx2v i2v I mean, movement direction is more accurately expressed in the gen according to specifics.
In this gen it previously would hold the book close to the chest, with the new lightx2v it consistently holds the book out towards the camera.
A ran it a few times with the newer version and got the same, better, positioning of the book.
The prompt was different by one or two words on this gen, but none of the movement direction was changed.
