When going into a folder in Folder view, and there are videos within a folder, they’re all put next to each other, making a video a different height than the folder. How about separating the two into sections. If there are folders in a folder of videos, put all the videos together first, and if there’s less than what fits in a row, leave a space where other folders for the last row would be, and move to the next line with the first row of videos so it doesn’t look like this.
… or make the two item thumbs the same height/widrh?
There’s not a reason to make the folders the aspect ratio of a poster, and making a video in Folder video poster size also doesn’t make sense. The folder can really be 1:1.
