Movie covers on 4kuhd, Blu-rays uses a 1.2655 ratio between length/width.
Movie posters use a 1.4725 ratio between length/width.
Make it possible to switch to accepting movie covers. This means that the grid must be able to adapt to 1.2655 ratios and the spacings must change accordingly between items.
This can be an advanced feature for users that want to customize and use covers they themselves have picked out.
This option will give the user the movie library feel (they can display the movies with their covers just like the ones they actually own) and will be a nice feature that requires very little programming on your end.
A box that you can tick that makes the change.
What happens is that thearound the movie poster changes to 1.2655 with spacings also accounting for this. The regular posters will center themselves within this box so there will be grey to the sides by default when you tick the box. You go in and change posters like you normally would but this time if you select a movie cover it will display fully and not cropped out like before. If you tick the box back from movie posters to movie covers then spacings anddimensions return to normal again.
A popup information note with “do you want to change poster dimensions to movie cover.” or something could be added for clarity
