How to download from a URL in JSON? Or others? (Help)

[cesario678]

I created a function with an API where it fetches multiple image URLs and stores them in JSON. Now I have doubts about how to download these URLs. Could someone help me?
Remember that these image files are actually MP4 videos, and even when downloading them with the .mp4 extension, the file becomes corrupted. Is there any way to fix this as well?

These links do not lead directly to video files to download.
There should be more accurate links to files, like http://site.com/video/title.mp4
