@Javi3rV :

I also thought about using multithreading and download all of them like there is no tomorrow but vimeo would take a look at net traffic and would suspect something

if so, you can tweak number of workers in line

with ThreadPoolExecutor(max_workers=15) as executor:

and, if wanted, set it to 1 for disable multithreading at all
I also thought about ability to download multiple urls and may be i came with solution a bit later

I find it useful to have a way to avoid asking for user input, so that the whole thing can be easily scripted.
It's often just a matter of supporting env vars such as

url = url = os.getenv("SRC_URL") or input('enter [master|playlist].json url: ')
name = os.getenv("OUT_FILE") or input('enter output name: ')
max_workers = min(int(os.getenv("MAX_WORKERS", 5)), 15)

or/and if you prefer the launch args could be parsed.

Anyway IMHO multithreading is a different matter: as too many simultaneous requests from the same IP are a PITA, I consider a simple loop safer.

I'll check for using json contents for tests.
