best way to record samples/clips?

so i have never really used recorded samples from movies, tv, etc. and when i have i always used clips that were already
recorded and in a .wav format. what is the best/easiest way to use my computer to record clips from a source like youtube
or netflix? i’d like to use some clips from a few youtube clips of old tv shows.

For youtube, there’s a renoise tool that lets you put in a url and download a wav straight to renoise.

do you know the name of the tool?

Here it is:

thank you so much!
