"A Christmas Fantasy" is a very short film which is part of a collection currently on Freevee. It's entitled "Vintage Christmas Classics", though they sure use the word 'classics' very broadly! Mostly, they are terrible shorts which probably are best forgotten.
As for this film, IMDB says it consists of still photos, but in addition to the stills, you have a lot of cheap film clips as well. It also features a Santa more hellish and scary than anything you'd ever see in a horror movie!
The film has little in the way of plot. A couple unattractive kids fall asleep on a chair next to a Christmas tree and 'Santa' arrives. And then it ends!
The overall film is terrible and rather pointless...even compared to the other terrible and pointless shorts in this collection.
