Apple interpolates video clips from 320 × 240 to 640 × 480
Apple is accused of interpolating some video clips, increasing their resolution from 320 × 240 to 640 × 480 pixels using software methods.
A careful analysis of the screenshots makes it possible to accurately determine that a video of an enlarged size is nothing more than interpolation. The quality is exactly the same, only the size of the video files is different (about three times).
The use of these dishonest methods is associated with the opening of the updated iTunes Store video store , at the same time with which the company announced that all the films in the store will have a resolution of 640 × 480.

Apple's interpolation quality is pretty bad. You would get better results on your computer. Let Apple have allowed to download videos of small size 320 × 240, but no. Instead, they, hostages of their own marketing, increase the size of files by about three times and sell, in fact, the same material as “high-resolution video”.
