how to add movie artwork to iTunes 12.1.0.50

same results (or lack therein) were the norm after updating to iTunes 12, but this solution works for me.

-- select the movie/tv show

-- Get Info

-- select the Artwork tab

-- Paste the artwork from the clipboard (you DID copy an image into the clipboard, right? lol) ...

-- the artwork then appears. done.

Note: NO border or box appears when you first open the Artwork tab, but the Edit menu has the Paste feature active.

Hit Control + Click on greyed out movie

Select “Delete”

Select “Hide Movie”

Do this for each greyed out movie

THEN

On top right of iTunes, click on your account name drop down menu

Select “Account Info”

Enter your iTunes password

Select “View Account”

Scroll down to “Hidden Purchases”

Select “Manage”

Ensure you are on “Movies” page in Hidden Purchases (on top right of Hidden Purchases)

Select “Unhide” for each movie that you have hidden

Return to “My Movies” page in iTunes and verify that each (formerly) greyed out movie artwork has been restored

iTunes 12.4.6.1 Missing Movie Artwork.

Had a similar problem with movie posters that dropped off of the Info area or would not allow me to add the posters when the file was hosted on a NAS.

I just moved all my movies to a NAS from a local connected USB drive. Any new movie that I loaded to the NAS would not allow me to add Movie Posters to the Artwork of the iTunes Info. But, if you move the movie to your desktop then Drag movie into iTunes and add artwork and all the other info it will stick. Then delete out of iTunes and put into your NAS or remote storage and point to new movie file location. Sort of a pain but it works like a champ.
